A patient with hypertrophic cardiomyopathy accompanied by right ventricular dilation of unknown cause. (1/927)

Hypertrophic cardiomyopathy (HCM) is a disease characterized by an unknown cause of hypertrophy in the left or right ventricle. The dilated phase of HCM shows disease conditions resembling dilated cardiomyopathy, such as ventricular dilation, thin ventricular wall, and reduction of the ejection fraction. A patient presented with left ventricular concentric hypertrophy accompanied by right ventricular dilatation of unknown cause. Right ventricular endomyocardial biopsy specimens showed characteristic myocardial disarray. Therefore, there is the possibility that the patient had right and left ventricular HCM in the process toward the dilated phase, in which dilatation first occurred in the right ventricle.  (+info)

Prognostic value of nocturnal Cheyne-Stokes respiration in chronic heart failure. (2/927)

BACKGROUND: Nocturnal Cheyne-Stokes respiration (CSR) occurs frequently in patients with chronic heart failure (CHF), and it may be associated with sympathetic activation. The aim of the present study was to evaluate whether CSR could affect prognosis in patients with CHF. METHODS AND RESULTS: Sixty-two CHF patients with left ventricular ejection fraction /=30/h and left atria >/=25 cm2. CONCLUSIONS: The AHI is a powerful independent predictor of poor prognosis in clinically stable patients with CHF. The presence of an AHI >/=30/h adds prognostic information compared with other clinical, echocardiographic, and autonomic data and identifies patients at very high risk for subsequent cardiac death.  (+info)

Influence of increased abdominal pressure on steady-state cardiac performance. (3/927)

The effect of steady-state increases in abdominal pressure (Pab) on cardiac performance was studied in seven acutely instrumented swine with pneumoperitoneum (PP). The animal was placed on volume-preset ventilation, and PP was created by air insufflation. Cardiac output (CO), right atrial (Pra), left atrial (Pla), pericardial (Ppe), and abdominal inferior vena cava pressures (Pivc) were measured while Pab was increased from baseline to 7.5, 15, and 30 mmHg (PP7.5, PP15, and PP30, respectively). Cardiac function curves of the right and left ventricle (RV and LV, respectively) were compared between baseline and PP30. CO presented biphasic changes, with an inital slight increase at PP7.5 followed by a fall at PP30. A significant discrepancy was observed between Pra and Pivc at PP15 and PP30, consistent with development of a "vascular waterfall." Transmural Pla (Pla - Ppe) showed parallel changes with CO, whereas transmural Pra (Pra - Ppe) exhibited a sustained increase. The RV cardiac-function curve was more depressed than was that of the LV at PP30; this suggests an increased RV afterload produced by the elevated airway pressure. These results support the hypothesis that our previously proposed concept of abdominal vascular zone conditions (M. Takata, R. A. Wise, and J. L. Robotham. J. Appl. Physiol. 69: 1961-1972, 1990) is also applicable to steady-state hemodynamic analyses. The abdominal zones appear to play an important role in determining CO, with increases in Pab, by modulating systemic venous return and the LV preload. Simultaneous measurements of Pra and Pivc may provide useful information in the hemodynamic care of patients with elevated Pab.  (+info)

Effects of 1-(2,6-dimethylphenoxy)-2-(3,4-dimethoxyphenylethylamino) propane hydrochloride on heart function, lactate dehydrogenase and its isoenzymes in rats with cardiac hypertrophy. (4/927)

AIM: To investigate the effects of 1-(2,6-dimethylphenoxy)-2-(3,4-dimethoxyphenylethylamino) propane hydrochloride (DDPH) on cardiac systolic and diastolic function, lactate dehydrogenase (LDH) activity, and LDH isoenzymes in rats with cardiac hypertrophy. METHODS: The cardiac hypertrophy of rats was induced by partly occluding abdominal aorta. The rats were given i.g. DDPH for 8 wk 4 wk after operation, and isolated working heart was made. RESULTS: Eight wk later, in model group, left ventricle systolic pressure (LVSP), LV + dp/dtmax, -dp/dtmax and aorta pressure (AP) decreased by 20.2%, 20.0%, 41.4%, and 13.6%, respectively. Left ventricle ending diastolic pressure (LVEDP) increased by 173.9%. The hemodynamic study showed that flowing liquid of aorta (AF) and coronary (CF) and cardiac output (CO) decreased by 49.4%, 41.2%, and 48.9%, respectively. After the rats were given i.g. DDPH, the all above-mentioned parameters recovered to different degrees. Under condition of cardiac hypertrophy, LDH isoenzymes and subunits changed significantly. Isoenzymes LDH3, LDH4, and LDH5, especially LDH5 increased, LDH1 decreased, subunit M in hypertrophied heart increased 1.69 times than that in normal heart. DDPH could decrease subunit M and increase subunit H. CONCLUSION: DDPH can increase cardiac function, coronary flow and reverse changes of LDH isoenzymes in rats with cardiac hypertrophy.  (+info)

Cardiac-directed adenylyl cyclase expression improves heart function in murine cardiomyopathy. (5/927)

BACKGROUND: We tested the hypothesis that increased cardiac myocyte adenylyl cyclase (AC) content increases cardiac function and response to catecholamines in cardiomyopathy. METHODS AND RESULTS: Transgenic mice with cardiac-directed expression of AC type VI (ACVI) were crossbred with mice with cardiomyopathy induced by cardiac-directed Gq expression. Gq mice had dilated left ventricles, reduced heart function, decreased cardiac responsiveness to catecholamine stimulation, and impaired beta-adrenergic receptor (betaAR)-dependent and AC-dependent cAMP production. Gq/AC mice showed improved basal cardiac function in vivo (P=0.01) and ex vivo (P<0.0005). When stimulated through the betaAR, cardiac responsiveness was increased (P=0.02), and cardiac myocytes showed increased cAMP production in response to isoproterenol (P=0.03) and forskolin (P<0.0001). CONCLUSIONS: Increasing myocardial ACVI content in cardiomyopathy restores cAMP-generating capacity and improves cardiac function and responsiveness to betaAR stimulation.  (+info)

Ten year survival after heart transplantation: palliative procedure or successful long term treatment? (6/927)

OBJECTIVE: To investigate the long term outcome and prognostic factors after heart transplantation. SETTING: University hospital. SUBJECTS: 120 heart transplant patients (98 male, 22 female; underlying disease: dilated cardiomyopathy in 69, coronary artery disease in 42, miscellaneous in nine) who had undergone heart transplantation between October 1984 and October 1987. Immunosuppressive treatment was comparable in all patients and rejection episodes were treated in a uniform manner. METHODS: Functional status, quality of life, and potential predictors for long term survival were investigated. RESULTS: Actuarial survival rates were 65% at five years and 48% at 10 years; 58 patients survived > 10 years. The major causes of death were cardiac allograft vasculopathy (39%), acute rejection (18%), infection (11%), and malignancy (11%). Long term survivors had good exercise tolerance assessed by the New York Heart Association classification: 47 (81%) in grade I/II; 11 (19%) in grade III/IV. Echocardiography showed good left ventricular function in 48 patients. On angiography, severe allograft vasculopathy was present in only 16 patients (28%). Renal function was only slightly impaired, with mean (SD) serum creatinine of 148.5 (84.9) micromol/l. Multiple potential predictors of long term survival were analysed but none was found useful. CONCLUSIONS: Heart transplantation represents a valuable form of treatment. Survival for more than 10 years with a good exercise tolerance and acceptable side effects from immunosuppression can be achieved in about 50% of patients.  (+info)

Enhancement of cardiac function after adenoviral-mediated in vivo intracoronary beta2-adrenergic receptor gene delivery. (7/927)

Exogenous gene delivery to alter the function of the heart is a potential novel therapeutic strategy for treatment of cardiovascular diseases such as heart failure (HF). Before gene therapy approaches to alter cardiac function can be realized, efficient and reproducible in vivo gene techniques must be established to efficiently transfer transgenes globally to the myocardium. We have been testing the hypothesis that genetic manipulation of the myocardial beta-adrenergic receptor (beta-AR) system, which is impaired in HF, can enhance cardiac function. We have delivered adenoviral transgenes, including the human beta2-AR (Adeno-beta2AR), to the myocardium of rabbits using an intracoronary approach. Catheter-mediated Adeno-beta2AR delivery produced diffuse multichamber myocardial expression, peaking 1 week after gene transfer. A total of 5 x 10(11) viral particles of Adeno-beta2AR reproducibly produced 5- to 10-fold beta-AR overexpression in the heart, which, at 7 and 21 days after delivery, resulted in increased in vivo hemodynamic function compared with control rabbits that received an empty adenovirus. Several physiological parameters, including dP/dtmax as a measure of contractility, were significantly enhanced basally and showed increased responsiveness to the beta-agonist isoproterenol. Our results demonstrate that global myocardial in vivo gene delivery is possible and that genetic manipulation of beta-AR density can result in enhanced cardiac performance. Thus, replacement of lost receptors seen in HF may represent novel inotropic therapy.  (+info)

Noninvasive assessment of the cardiac baroreflex: response to downward tilting and comparison with the phenylephrine method. (8/927)

OBJECTIVES: We studied the relation between changes in systolic blood pressure and RR interval during downward tilting in comparison with assessment of baroreflex sensitivity (BRS) measured by the phenylephrine method (Phe-BRS) and with measures of heart rate variability (HRV). BACKGROUND: The method most extensively used for assessing BRS involves bolus injections of phenylephrine. Several noninvasive methods proposed to assess BRS have not been widely applied in the clinical setting. METHODS: Sixteen healthy male volunteers were studied (mean age +/- SD 27.5+/-4.6 years). Arterial blood pressure using tonometry and electrocardiogram was simultaneously recorded. After 20 min of 70 degrees upright tilting, the table was returned to supine position at a speed of 3.2 degrees/s. Subsequently, BRS was assessed using an intravenous bolus injection of phenylephrine (2 to 3 microg/kg). Heart rate variability under resting conditions also was analyzed. RESULTS: In all subjects, a beat to beat systolic blood pressure increase associated with corresponding RR interval lengthening was observed during downward tilting as well as during phenylephrine administration. During both testing procedures, these two variables showed linear correlation, and the slope of regression line during downward tilting (DT-BRS) correlated significantly with Phe-BRS (r = 0.79, p = 0.0003). The DT- and Phe-BRS also correlated significantly with the high frequency component of resting HRV (r = 0.70, p = 0.0023 for DT-BRS; r = 0.58, p = 0.0185 for Phe-BRS). CONCLUSIONS: We conclude that in a small homogeneous group DT-BRS provided an assessment of reflex cardiac vagal function comparable to that obtained by the phenylephrine method.  (+info)

The complexities of catecholamine physiology have intrigued physicians and the public alike for centuries. Epinephrine was isolated in 1897 by John Jacob Abel (1), and in parallel in 1901 by the Japanese scientist Jokichi Takamine (2), who called it adrenaline. Quickly the positive inotropic and chronotropic effects of catecholamines were appreciated and exploited, but by the second half of the 20th century the adverse effects of chronic exposure were increasingly recognized, including their roles in hypertension and heart failure (HF), eventually yielding β-adrenoceptor blockers as HF therapy.. More recently the notion that short-term effects of catecholamines are temporary and reversible has been challenged. Acute HF in the context of adrenergic storms has highlighted that high circulating catecholamine levels can either be toxic or cause acute negative inotropic effects. However, the long-term effects of these acute surges in endogenous or exogenous catecholamines and associated acute ...

ANSWER: In the most severe cases, some dogs may survive only weeks to a few months. Occasionally, dogs may do well clinically for 1-2 years. Treatment of DCM is aimed at both improving the hearts function and controlling the signs of congestive heart failure.
Three indexes developed originally to assess left ventricular contractile performance were applied instead to the right ventricle (RV) in 11 conscious dogs: the relation between stroke work and end-diastolic volume (EDV), termed the preload recruitable stroke work (PRSW) relation; the end-systolic pressure-volume (ESPV) relation; and the maximum dP/dt (dP/dtmax)-EDV relation. The reproducibility, inotropic sensitivity, chronotropic sensitivity, and afterload sensitivity of these RV relations were compared. RV volume was determined with an ellipsoidal shell subtraction model from orthogonal dimensions measured by sonomicrometry. RV transmural pressure was measured with micromanometers. After autonomic blockade, preload was varied by repeated, transient vena caval occlusions before and during partial occlusion of the main pulmonary artery, after release of the pulmonary arterial occlusion, after calcium infusion, and over a range of heart rates induced by atrial pacing. The slope and volume-axis ...

Intramyocardial injections of cultured fetal cardiomyocytes after infarction in female rats in an ischaemia-reperfusion model increased ejection fraction at one month; male cells transplanted into the female hosts were identified at necropsy by detection of the Y chromosome using an in situ hybridisation technique.7 In a mouse model of doxorubicin induced global cardiomyopathy,8 local transplantation of fetal cardiomyocytes can also improve global function, suggesting the intervention of paracrine factors. Comparing intramyocardial injections of cultured fetal cardiomyocytes and allogenic fetal skeletal myoblasts after infarction in rats,9 the functional equivalence of these two types of cells was demonstrated with decreased cavity dilatation and increased ejection fraction of similar magnitude; this anti-remodelling effect was more pronounced for the lowest ejection fractions (, 40%) with an approximately 30% relative increase in ejection fraction without cavity dilatation. Similar results ...
In most cases, edema is caused by pregnancy, menopause, burns, contraceptive pills and any other pill containing estrogen, medications like vasodilators and NSAIDs, physical inactivity, and poor diet. The symptoms of edema depend on the root cause and they typically develop slowly over time. The underlying cause can be determined by urine tests, liver function tests, blood tests, heart function tests, or X-ray.. While most causes are not serious, sometimes edema can result from an underlying condition like heart failure, kidney disease, liver disease or diabetes, meaning that it shouldnt be taken for granted. After all, edema itself is quite common, currently affecting approximately 4.4 million Americans.. Read on to learn more about the most common causes of the edema and the tips on how to prevent it, of course as long as a serious underlying disease is not to blame.. ...
