Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.

Controlled physical activity which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used.

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)

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)
Given the potential overlap of insulin and IGF-1 signaling we sought to determine if both signaling pathways could contribute to exercise-induced cardiac hypertrophy following shorter-term exercise training. (elsevier.com)
The extent of cardiac hypertrophy following exercise training in CIGFRKO and CIRKO mice was comparable to that in control mice. (elsevier.com)
In contrast, exercise-induced cardiac hypertrophy was significantly attenuated in IGFR-/-IR+/- and IGFR+/-IR-/- mice. (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)
Swimming exercise, which is not accompanied by Gq activation, induced a normal cardiac response, while Rgs2 deletion in Galphaq-overexpressing hearts exacerbated hypertrophy and dilation. (tamu.edu)
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)

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)

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)
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)
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)

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)

In the cyclin D2 null mice, cardiac function was not impacted even though the hypertrophic response was blunted and a number of signaling pathways are differentially regulated by exercise. (elsevier.com)
Thus, IGF-1 and exercise activates both IGF1R and IR in the heart, and IGF1R- and IR-mediated signals may serve redundant roles in the hypertrophic responses of the heart to exercise training. (elsevier.com)
Objective: Assess hypertrophic response of the association of thyroid hormone and exercise in the rat heart. (bvsalud.org)
