Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.
An island in the Greater Antilles in the West Indies. Its capital is Kingston. It was discovered in 1494 by Columbus and was a Spanish colony 1509-1655 until captured by the English. Its flourishing slave trade was abolished in the 19th century. It was a British colony 1655-1958 and a territory of the West Indies Federation 1958-62. It achieved full independence in 1962. The name is from the Arawak Xaymaca, rich in springs or land of springs. (From Webster's New Geographical Dictionary, 1988, p564 & Room, Brewer's Dictionary of Names, 1992, p267)
A group of diseases in which the dominant feature is the involvement of the CARDIAC MUSCLE itself. Cardiomyopathies are classified according to their predominant pathophysiological features (DILATED CARDIOMYOPATHY; HYPERTROPHIC CARDIOMYOPATHY; RESTRICTIVE CARDIOMYOPATHY) or their etiological/pathological factors (CARDIOMYOPATHY, ALCOHOLIC; ENDOCARDIAL FIBROELASTOSIS).
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
A disease of the CARDIAC MUSCLE developed subsequent to the initial protozoan infection by TRYPANOSOMA CRUZI. After infection, less than 10% develop acute illness such as MYOCARDITIS (mostly in children). The disease then enters a latent phase without clinical symptoms until about 20 years later. Myocardial symptoms of advanced CHAGAS DISEASE include conduction defects (HEART BLOCK) and CARDIOMEGALY.
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.
Heart Defects, Congenital
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
A type of strength-building exercise program that requires the body muscle to exert a force against some form of resistance, such as weight, stretch bands, water, or immovable objects. Resistance exercise is a combination of static and dynamic contractions involving shortening and lengthening of skeletal muscles.
The oxygen consumption level above which aerobic energy production is supplemented by anaerobic mechanisms during exercise, resulting in a sustained increase in lactate concentration and metabolic acidosis. The anaerobic threshold is affected by factors that modify oxygen delivery to the tissues; it is low in patients with heart disease. Methods of measurement include direct measure of lactate concentration, direct measurement of bicarbonate concentration, and gas exchange measurements.
Muscle Stretching Exercises
Exercises that stretch the muscle fibers with the aim to increase muscle-tendon FLEXIBILITY, improve RANGE OF MOTION or musculoskeletal function, and prevent injuries. There are various types of stretching techniques including active, passive (relaxed), static, dynamic (gentle), ballistic (forced), isometric, and others.
Pulmonary Gas Exchange
Physical Education and Training
Asthma attacks following a period of exercise. Usually the induced attack is short-lived and regresses spontaneously. The magnitude of postexertional airway obstruction is strongly influenced by the environment in which exercise is performed (i.e. inhalation of cold air during physical exertion markedly augments the severity of the airway obstruction; conversely, warm humid air blunts or abolishes it).
Exercise Movement Techniques
A state arrived at through prolonged and strong contraction of a muscle. Studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion. Muscle fatigue in short-term maximal exercise is associated with oxygen lack and an increased level of blood and muscle lactic acid, and an accompanying increase in hydrogen-ion concentration in the exercised muscle.
The act of breathing with the LUNGS, consisting of INHALATION, or the taking into the lungs of the ambient air, and of EXHALATION, or the expelling of the modified air which contains more CARBON DIOXIDE than the air taken in (Blakiston's Gould Medical Dictionary, 4th ed.). This does not include tissue respiration (= OXYGEN CONSUMPTION) or cell respiration (= CELL RESPIRATION).
Cardiovascular Physiological Phenomena
Analysis of Variance
Respiratory Function Tests
Studies comparing two or more treatments or interventions in which the subjects or patients, upon completion of the course of one treatment, are switched to another. In the case of two treatments, A and B, half the subjects are randomly allocated to receive these in the order A, B and half to receive them in the order B, A. A criticism of this design is that effects of the first treatment may carry over into the period when the second is given. (Last, A Dictionary of Epidemiology, 2d ed)
A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

Carbohydrates present in food comprising digestible sugars and starches and indigestible cellulose and other dietary fibers. The former are the major source of energy. The sugars are in beet and cane sugar, fruits, honey, sweet corn, corn syrup, milk and milk products, etc.; the starches are in cereal grains, legumes (FABACEAE), tubers, etc. (From Claudio & Lagua, Nutrition and Diet Therapy Dictionary, 3d ed, p32, p277)
The active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.
A status with BODY WEIGHT that is grossly above the acceptable or desirable weight, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care. (Dictionary of Health Services Management, 2d ed)
Body Temperature Regulation
Forced Expiratory Volume
Measure of the maximum amount of air that can be expelled in a given number of seconds during a FORCED VITAL CAPACITY determination . It is usually given as FEV followed by a subscript indicating the number of seconds over which the measurement is made, although it is sometimes given as a percentage of forced vital capacity.

Sympathetic Nervous System
The thoracolumbar division of the autonomic nervous system. Sympathetic preganglionic fibers originate in neurons of the intermediolateral column of the spinal cord and project to the paravertebral and prevertebral ganglia, which in turn project to target organs. The sympathetic nervous system mediates the body's response to stressful situations, i.e., the fight or flight reactions. It often acts reciprocally to the parasympathetic system.

miR-17-3p contributes to exercise-induced cardiac growth and protects against myocardial ischemia-reperfusion injury
Limited microRNAs (miRNAs, miRs) have been reported to be necessary for exercise-induced cardiac growth and essential for protection against pathological cardiac remodeling. Here we determined members of the miR-17-92 cluster and their passenger miRNAs expressions in two distinct murine exercise models and found that miR-17-3p was increased in both. miR-17-3p ... read more promoted cardiomyocyte hypertrophy, proliferation, and survival. TIMP-3 was identified as a direct target gene of miR-17-3p whereas PTEN was indirectly inhibited by miR-17-3p. Inhibition of miR-17-3p in vivo attenuated exercise-induced cardiac growth including cardiomyocyte hypertrophy and expression of markers of myocyte proliferation. Importantly, mice injected with miR-17-3p agomir were protected from adverse remodeling after cardiac ischemia/reperfusion injury. Collectively, these data suggest that miR-17-3p contributes to exercise-induced cardiac growth and protects against adverse ventricular remodeling. miR-17-3p may ...

Exercise Intolerance in Renal Failure - Full Text View - ClinicalTrials.gov
Patients with chronic kidney disease have profound exercise intolerance which contributes to an increased risk of cardiovascular disease. The investigators have found that chronic kidney disease patients have an exaggerated increase in blood pressure during certain forms of exercise that could certainly contribute to exercise dysfunction as well as cardiovascular risk. The investigators will test the mechanisms underlying this exaggerated blood pressure response, as well as the potential benefits of short-term tetrahydrobiopterin (BH4) with folic acid on both exercise dysfunction and cardiovascular risk factors in chronic kidney disease. The investigators will test whether short-term treatment with tetrahydrobiopterin (BH4), a cofactor for nitric oxide, together with folic acid improves inflammation, vascular health, and adrenaline levels, both at rest and during exercise in chronic kidney disease ...

Treadmill BP in Simulated Peripheral Artery Disease
What is driving the exaggerated blood pressure response to exercise in patients with peripheral arterial disease (PAD)? In this podcast, Editor in Chief Irving H. Zucker (University of Nebraska Medical Center) interviews senior author Gail Thomas (Penn State College of Medicine) and content expert Hanjun Wang (University of Nebraska Medical Center) about the unique study by Kuczmarski et al. Thomas and co-authors used telemetry to record blood pressure during exercise in conscious animals, both before and after bi-lateral femoral artery ligation. The studied was conducted over a period of two months, a technical success given that the authors used chronically-instrumented conscious animals. Thomas and collaborators found that the blood pressure response was exaggerated as early as 3 days after femoral artery ligation and lasted for the duration of the experiment in both female and male mice. Are the mechanisms that play a role in blood pressure response to short-term ligation, such as cytokines ...

Pertussis in Soldiers, Israel - Volume 11, Number 3-March 2005 - Emerging Infectious Disease journal - CDC
To the Editor: The role of adults as reservoirs of pertussis was previously well established (1-7). Young army recruits undergoing basic training in the Israeli Defense Force constitute a unique adult population because of their special living and service conditions. This and the fact that they are not vaccinated with the diphtheria, tetanus, and pertussis (DTP) vaccine after the age of 1 year (unlike children in most of the Western countries) led us to hypothesize that this semiclosed population may have an exceptionally high risk for pertussis. These young soldiers are on leave on weekends, during which time they come in close contact with susceptible family members, including young infants, and may thus facilitate the import and export of pertussis between the military setting and the general population. An outbreak of pertussis that recently occurred among infantry soldiers (8) indicated the need to conduct the present study, in which we sought to evaluate the prevalence and incidence of ...
marathon runner height
writes: Who knows for sure - it seems most elite marathon runners tend to be on the short side. Luke Puskedra is the newest member of a select group. However, this is inevitable since it appears the suggested values were based on real-life heights and weights of professional runners. After delivering PPE at the height of the pandemic, the pre-med student is running the virtual New York City Marathon to raise funds for health care workers in need. The theory is that, because foot size doesnt necessarily increase in proportion to height, taller runners are subject to greater biomechanical forces, and could have an increased susceptibility to injury.

Fatal fall of Wright airship - Wikisource, the free online library
WASHINGTON, Sept. 17.―Falling from a height of 75 feet, Orville Wright and Lieut. Thomas E. Selfridge of the Signal Corps were buried in the wreckage of Wrights aeroplane shortly after 5 oclock this afternoon. The young army officer died at 8:10 oclock to-night. Wright is badly hurt, although he probably will recover. The flying machine is a mass of tangled wires, torn and twisted planes, and tattered canvas. The accident was due to the breaking of one of the blades of the propeller on the left side.. Although there had been but a handful of people at the aeronautical testing grounds at Fort Myer during the last few days, fully 2,000 had gathered by 4:30 this afternoon. The aeroplane was still in its shed, but Mr. Wright arrived a few minutes later and ordered it taken to the northern end of the field, to be placed on the starting track in readiness for a flight.. Selfridge In First.. Everybody was ordered back from the machine, and Mr. Wright turned to Lieut. Selfridge and said: You might ...

Abstract 783: Exaggerated Blood Pressure Variability Aggravates Hypertensive Cardiac Remodeling through the Angiotensin II...
Background: Hypertensive patients with large blood pressure (BP) variability have greater risks of cardiovascular events and exaggerated end-organ damages. Recently, we have shown that acute pressure overload triggers transient perivascular inflammation.. Hypothesis: We assessed the hypothesis that large BP variability exaggerates hypertensive cardiac remodeling through the activation of myocardial inflammation.. Methods and Results: A new rat model of chronic hypertension with exaggerated BP variability was created by performing bilateral sino-aortic denervation (SAD) in spontaneous hypertensive rats (SHRs). Seven weeks after SAD (n=10) or sham (n=7) operation (week 7), 24-hour BP was monitored telemetrically in SAD+SHRs and sham+SHRs. Although mean BP was similar in the two groups, SAD+SHRs had greater BP variability (larger standard deviation and covariance of mean BP), compared with sham+SHRs. Both the two groups showed concentric left ventricular (LV) hypertrophy, and SAD aggravated LV ...
No effect of partial-body cryotherapy on restoration of countermovement-jump or well-being performance in elite rugby union...
Purpose:Partial body cryotherapy (PBC) has been shown to be beneficial for post-exercise recovery, however, no study has demonstrated the effectiveness of PBC as a recovery modality following elite rugby union (RU) training. RU is a unique sport that involves high velocity collisions with minimal protective wear and may represent a situation that could induce greater performance decrements than other sports, thus PBC could be beneficial. The application of PBC in real-world, as opposed to the laboratory setting, has rarely been investigated during the competitive phase of a playing season and warranted investigation.Methods:In a counterbalanced sequential research design, professional rugby athletes (n = 18, age, 25.4 ± 4.0 years; training age, 7.2 ± 4.0 years; mass, 99.8 ± 10.6 kg and height 188.3 ± 6.0 cm) were assigned to a 12-week PBC intervention, washout period (4 weeks) and reassessed as their own controls. Total self-reported well-being, muscle soreness, sleep quality and ...
Magiran | The Journal of Tehran University Heart Center، Volume:14 Issue:4, 2019
Totally, 142 HF patients with midrange ejection fraction (HFmrEF) and reduced ejection fraction (HFrEF) were enrolled in the study. There was a significantly correlation both between the EF and the EPSS and between the EF and the LVIDd/EPSS (P,0.001). In both HFmrEF and HFrEF groups, the correlation between the LVIDd/EPSS and the EF was more significant than was the correlation between the EPSS and the EF (P,0.001). The results of the linear regression analysis indicated that the LVIDd/EPSS was an independent predictor of the HFmrEF and the HFrEF (P,0.001). In the patients with EPSS≤12, there was a significant association between the EF and the LVIDd/EPSS (P,0.001) but not between the EF and the EPSS(P,0.05).

Foolishness led to death of the marathon runner from Hamburg :: News ::: SCC | EVENTS
2002-10-07. The runner who collapsed last Sunday during the real,- BERLIN-MARATHON could not have been saved by the rescue workers, who were there immediately. This is the conclusion made by the doctor in charge during the race, Dr. Willi Heepe, after having received background medical information about the deceased man. The 50-year-old man from Hamburg was a top manager who despite his stress at work put himself under pressure in his free time, as well. The runner, who was not married and did not have any children, also suffered high blood pressure. The race on Sunday was the mans 4th marathon this year. Just three weeks earlier, he had pushed himself to the limit in a marathon in Münster. He had announced to his doctor before the real,- BERLIN-MARATHON that he definitely wanted to make it under three hours. As he reached the last few kilometres on the Kurfürstendamm and he was getting close to his time limit, he tried to extract the last power out of his body and then collapsed. Since he ...
Diary of a Rubbish Marathon Runner: June 2008
Two miles earlier I would have scoffed at the preposterous thought of running 2 miles at that pace. Things had changed, however, and all of a sudden I felt really calm and relaxed, and I just knew I would do it. I knew it would hurt, I knew it would be by far the best finish I had ever produced in a marathon, but I was in The Zone, and I wasnt going to snap out of it. I still kept passing runner after runner, and I knew that I would be able to push on until the end. The last mile finally spots a decent number of spectators, and they finally made some noise, which was good. It was just after the 25 mile marker, with a mile to go, that I got hit by the first cramp. In my last marathon, in Loch Ness, a similar thing had happened over the last two miles, and I had slowed down a lot. This time it was different, however; the cramps were not caused by mere fatigue but by the fact that I was basically running faster than my body was able to do for a sustained period of time. However, the cramps never ...

Performance of the 2010 European Society of Cardiology criteria for ECG interpretation in athletes | Heart
Results Application of the 2010 ESC criteria, compared with the 2005 criteria, reduced the number of participants with abnormal ECG findings from 83/508 (16.3%) to 49/508 (9.6%). The reduction in the number of abnormal ECGs was driven by the reclassification of participants with isolated QRS voltage criteria for left ventricular hypertrophy from abnormal to normal. Of the 49 participants with abnormal ECGs, 14/49 (29%) had a single ECG abnormality and 35/49 (71%) had two or more abnormalities. The use of the 2010 criteria was associated with improved specificity (reduction in the false positive rate) and preserved sensitivity when compared with the 2005 criteria. ...

The Cushie Files: Do the Things You Did at First
Recalling my most fit season of life, I realized I had been neglecting fitness care. As a pedestrian, I havent necessarily needed to do much intentional cardio to stay shapely, but I remembered how much I loved running before I had Aviel. As I researched adrenal fatigue, which is how I have been self-treating prior to discovery that my Cushings is adenoma related, I learned that running actually puts stress on the body and causes a release of cortisol. Its not necessarily recommended for those struggling with adrenal problems, but I departed from the suggestion and went for it. My logic is that the good endorphins are worth the small amount of stress. Im not a marathon runner... just 20 minutes at a time. And I think this was a good choice. I feel so much better when Im running regularly. It builds my confidence to meet my goals, and it increases my energy through out the day. I really do have this sense that I am more than a conqueror. For that, it is totally worth it ...

- Exercise studies were performed on females from six different genetic mouse models that have been shown to exhibit alterations in pathological cardiac adaptation and hypertrophy. (elsevier.com)
- Impact statement: This research is relevant as the hypertrophic signaling pathways tested here have only been characterized for their role in pathological hypertrophy, and not in the context of exercise or physiological hypertrophy. (elsevier.com)
- Conclusion: The association of thyroid hormone with high-intensity exercise produced cardiac hypertrophy, and generated a standard hypertrophy not directly correlated to the degree of fibrosis. (bvsalud.org)
- Among the molecular, biochemical and cellular processes that orchestrate the development of the different phenotypes of cardiac hypertrophy in response to physiological stimuli or pathological insults, the specific contribution of exercise training has recently become appreciated. (bvsalud.org)
- Physiological cardiac hypertrophy involves complex cardiac remodeling that occurs as an adaptive response to static or dynamic chronic exercise, but the stimuli and molecular mechanisms underlying transduction of the hemodynamic overload into myocardial growth are poorly understood. (bvsalud.org)
- This review summarizes the physiological stimuli that induce concentric and eccentric physiological hypertrophy, and discusses the molecular mechanisms, sarcomeric organization, and signaling pathway involved, also showing that the cardiac markers of pathological hypertrophy (atrial natriuretic factor, β-myosin heavy chain and α-skeletal actin) are not increased. (bvsalud.org)
- There is no fibrosis and no cardiac dysfunction in eccentric or concentric hypertrophy induced by exercise training. (bvsalud.org)
- Here, we show that the angiotensin II type 1 (AT1) receptor is locally activated in pathological and physiological cardiac hypertrophy, although with exercise training it can be stimulated independently of the involvement of angiotensin II. (bvsalud.org)
- These findings show that glucocorticoids, rather than androgens, undergo adaptive changes in the circulation and in muscle during the development of exercise-induced cardiac hypertrophy. (unboundmedicine.com)
- When stressors that encourage this concentric hypertrophy are reduced or eliminated (either surgically corrected in the case of cardiac defects, or hypertension is reduced from diet and exercise) it is possible for the heart to undergo 'reverse remodeling', returning to a somewhat more 'normal' state instead of progressing to a dilated, pathologic phenotype. (wikipedia.org)
- This resulted in extreme cardiomyocyte proliferation and hypertrophy - excessive growth of the individual cardiomyocytes - leading to a giant heart (cardiomegaly) that left little room for blood to enter. (labroots.com)
- We propose that growth-factor-induced skeletal-muscle hypertrophy and changes in myofibre phenotype are mediated by calcium mobilization and are critically regulated by the calcineurin/NF-ATc1 signalling pathway. (nih.gov)
- Various aetiologies, in reaction to this, may induce compensatory mechanisms consisting of excentric (dilatation) and concentric hypertrophy. (ox.ac.uk)
- Design and patients Transmitral flow velocity profiles and standard non-invasive haemodynamic indices were obtained serially over seven days after symptom limited bicycle exercise tests in 18 patients with dilated cardiomyopathy and eight normal subjects. (bmj.com)
- Results The intensity of exercise, as assessed by respiratory gas analysis, was lower in patients with dilated cardiomyopathy than in normal subjects. (bmj.com)
- In contrast, patients with dilated cardiomyopathy showed a sustained decrease in the peak early diastolic filling velocity and a sustained increase in the deceleration time of early filling for 24 hours or more after exercise. (bmj.com)
- Because other haemodynamic variables recovered within one hour after exercise even in patients with dilated cardiomyopathy, the postexercise changes in ventricular filling were not explained by changes in loading conditions. (bmj.com)
- The efficacy of exercise training on a daily basis in dilated cardiomyopathy requires further evaluation. (bmj.com)
- In this study, we investigated the recovery process of the exercise induced diastolic left ventricular dysfunction in patients with dilated cardiomyopathy, using reproducible Doppler echocardiographic techniques. (bmj.com)

- Objective To investigate the recovery process of exercise induced diastolic dysfunction in heart failure, using Doppler echocardiographic techniques. (bmj.com)
- Conclusions Exercise induced diastolic left ventricular dysfunction of the failing heart persists for 24 hours or more after exercise. (bmj.com)
- Diastolic ventricular function of the failing heart is reported to be impaired during exercise. (bmj.com)
- 13 We further showed that the exercise induced diastolic dysfunction is attenuated by β adrenoceptor blockade. (bmj.com)
- 14 Because diastolic ventricular function is sensitive to transient myocardial metabolic insults, these findings suggest that exercise exerts a harmful metabolic effect on the failing myocardium through sympathetic stimulation. (bmj.com)
- Moreover, the exercise induced diastolic dysfunction may persist despite cessation of exercise. (bmj.com)
- 15 Thus even a physiological sympathetic activation during exercise may cause a sustained diastolic dysfunction in the failing heart because of its susceptibility to sympathetic stimulation. (bmj.com)
- Thus to determine a safe and logical exercise programme for patients with chronic heart failure it is important to clarify how long exercise induced diastolic dysfunction persists. (bmj.com)
- Determine whether resting and exercise-induced increases in LV diastolic pressures are related to exaggerated right-left heart coupling and to increased afterload. (strokecenter.org)
- The patient had a history of cardiomegaly with diastolic dysfunction and a bipolar disorder treated with lithium, lamotrigine, gabapentin. (swjpcc.com)
- 4-6 Moreover, exercise training may in itself have deleterious effects on the failing myocardium, because of the presence of several intrinsic abnormalities susceptible to exercise induced sympathetic stimulation and consequent tachycardia. (bmj.com)
- Myocardial tolerance to ischaemia/reperfusion (I/R) injury is improved by exercise training, but this cardioprotection is impaired by the chronic use of anabolic androgenic steroids (AAS). (nih.gov)
- If this is the case, the harmful metabolic effects may accumulate during exercise training or even during daily physical activities, promoting progression of myocardial failure. (bmj.com)
- and (3) while the training induction of myocardial hexokinase is inhibited by both beta 1- and beta 1 + beta 2-antagonists, myocardium may increase its ability to utilize lactate during exercise with training despite beta 1-blockade. (curehunter.com)
- Since mitochondria are responsible for the production of ATP, agents that interfere with the physiological myocardial mitochondrial function are expected to induce depletion of ATP pool. (southlaketimes.com)
