Diastolic intraventricular gradient in hypertrophic cardiomyopathy with apical hypertrophy.

Patients with hypertrophic cardiomyopathy and additional diastolic flow abnormalities are relatively rare. This report describes a case of apical ventricular hypertrophy with complete systolic obstruction and holodiastolic intraventricular pressure gradient.

Morphological quantification and differentiation of left ventricular hypertrophy in hypertrophic cardiomyopathy and hypertensive heart disease. A two dimensional echocardiographic study.

Differentiation between hypertrophic cardiomyopathy and hypertensive heart disease is a diagnostic challenge. M-mode echocardiography only permits assessment of hypertrophy in limited areas of the left ventricular wall. 2-D echocardiography allows visualization of most of the myocardium.

Impaired fibrinolytic capacity and tissue plasminogen activator release in patients with restenosis after percutaneous transluminal coronary angioplasty (PTCA).

To assess the role of the fibrinolytic system in the pathogenesis of restenosis after percutaneous transluminal coronary angioplasty (PTCA), we determined the components of this system in a retrospective study, including 16 patients with restenosis (gr. A) and 19 patients with long-term success (gr. B).

Ventricular function in cirrhosis and portasystemic shunt: a two-dimensional echocardiographic study.

Cardiovascular alterations such as increased heart rate, high cardiac output, reduced systemic vascular resistance, and in most of the cases, increased contractility parameters have been recognized in patients with advanced liver disease. Some investigators define a cirrhotic cardiomyopathy as a hyperdynamic failure of the heart. Consequently, in patients with cirrhosis, the risk of developing further circulatory deterioration may be increased in situations which stress the cardiovascular system.

Effects of long-term treatment with 120 mg of sustained-release isosorbide dinitrate and 60 mg of sustained-release nifedipine on myocardial perfusion.

Forty patients with coronary artery disease and scintigraphically proven myocardial ischemia were randomized into 2 groups receiving 4 weeks of treatment with either 120 mg of isosorbide dinitrate (ISDN) release or 60 mg of nifedipine release. Control exercise testing and myocardial scintigraphy were continued until anginal pains occurred, and repeated at identical individual workloads at the end of the 4 weeks of drug therapy. Myocardial scintigrams were evaluated by quantitative recording of counts in 60 segments/frame.
