This study assesses the relation between quantitative morphologic findings and left ventricular contractile function in patients with idiopathic dilated cardiomyopathy. Left ventricular endomyocardial catheter biopsy specimens were obtained from 73 patients during diagnostic heart catheterization. All patients had normal coronary arteriograms but abnormal(More)
We retrospectively studied 252 operated and 47 unoperated patients with isolated aortic valve disease. Aortic valve replacement (AVR) was recommended to all patients based on clinical and hemodynamic data. Preoperative hemodynamic and angiographic data were similar in operated and unoperated cohorts. Seventy-one percent of patients received a Björk-Shiley(More)
In 16 male patients with heart failure (NYHA II-III), the influence of a single dose of 25 mg captopril on the carotid sinus baroreceptor reflex was examined. Blood pressure fell significantly by 11 +/- 1.7 mm Hg (P less than 0.001), whereas heart rate remained unchanged (85 +/- 3 vs. 83 +/- 3 beats min-1). Carotid sinus baroreceptors were stimulated by(More)
In the isolated canine semitendinosus muscle supplied by two separate arteries and veins entering and leaving the muscle at a distance of about 12 cm from each other blood flow, O2-content, andpO2 in all four vessels were measured. Using the dye dilution technique the distribution of arterial inflow on both veins was determined. It was found that the muscle(More)
Hemodynamic function and overall coronary blood flow (argon technique) were measured in 16 patients with idiopathic dilated cardiomyopathy (IDC) and in 12 patients without detectable heart disease (control subjects) referred for precordial pain. In patients with IDC, coronary blood flow was normal at rest (78 +/- 17 ml/100 g-min versus 78 +/- 9 in control(More)
In patients with typical stress-induced anginal pain, normal coronary arteries, and unimpaired left ventricular performance at rest ("syndrome X"), a reduced coronary dilatory capacity, abnormal lactate metabolism during stress, and reduction of left ventricular functional reserve have been described. A group of 40 patients with syndrome X was followed for(More)
We analyzed data from 68 consecutive patients with congestive cardiomyopathy to evaluate the prognostic significance of quantitative morphologic findings in left ventricular myocardium as compared with the prognostic significance of left ventricular hemodynamics. Left ventricular endomyocardial biopsy specimens were obtained from all patients during(More)
Flavonoids are a ubiquitous family of phytochemicals that display a variety of biological effects, both beneficial and adverse depending on the individual compound. Certain flavonoids are genotoxic while others inhibit the genotoxicity of other mutagens. In the present studies, the mutagenicity of a mixture of polymethoxylated flavones (PMFs) purified from(More)
