A Case of Dilated Cardiomyopathy Associated with Pheochromocytoma

The diagnosis of dilated cardiomyopathy associated with pheochromocytoma was made in a 24 year old male on the basis of symptoms and signs, measurements of metabolites of catecholamine,echocardiography and radionuclide ventriculography were preformed and demonstrated. The presence of a tumor on both adrenal glands without definite distant metastasis was demonstrated by abdominal ultrasonography, CT scanning and 131I-MIBC scintigraphy. Surgical removal was performed after proper preoperative preparation with a-adrenergic blocker. During the surgery, neither significant arrhythmia nor severe change of blood pressure was observed. After surgery, cardiac function of the patient improved slowly and progressively.

The Effects of Handgrip and Cold Pressor Test on Mitral Flow in Patients with Left Ventricular Hypertrophy

BACKGROUND: Handgrip and cold pressor test may increase the afterload of the heart. And in left ventricular hypertrophy, it is known that mitral flow pattern is affected by decreased left ventricular compliance. We investigated the effects of handgrip and cold pressor test on mitral flow pattern in patients with left ventricular hypertrophy. METHODS: Handgrip and cold pressor test were performed in 12 subjects with left ventricular hypertrophy and in 14 healthy normal subjects. In supine position, blood pressure, heart rate and Doppler echocardiographic parameters(early peak flow velocity : E, atrial peak flow velocity : A) were obtained at rest, 1 and 3 minutes after the onset of tests respectively. RESULTS: In both groups, handgrip and cold pressor test increased blood pressure slightly without a statistical significance. In left ventricular hypertrophy group, there were significant increments in heart rates at 1 minute of handgrip (78+/-12min-1, p<0.001) and cold pressor test(77+/-7min-1, p<0.05) as compared to that at rest (73+/-12min-1). Mitral flow velocities did not show significant change after the tests in control group. A waves after 1 minute of handgrip(85.2+/-18.4cm/sec, p<0.05) and cold pressor test (87.3+/-17.8cm/sec, p<0.001) showed significant increases as compared to that at rest (79.1+/-14.9cm/sec) in left ventricular hypertrophy group whereas E waves did not. CONCLUSION: Although handgrip and cold pressor tests did not affect the mitral flow significantly in control group, each test raised A waves in left ventricular hypertrophy group. These results suggest that increased A waves may be due to a rise in afterload and decreased left ventricular compliance caused by handgrip and cold pressor test in left ventricular hypertrophy group.
