Significance of Left Ventricular Function for Perioperative Mortality in Surgical Treatment of Coronary Heart Disease
Aortocoronary bypass procedures have become a routine method in the treatment of coronary heart disease. Overall mortality in different centers is about 5%, but a marked increase of risk up to more than 50% is...

Disorders of Left Ventricular Performance in Congestive and Hypertrophic Obstructive Cardiomyopathy
While the histologic features of COCM and HOCM are well defined, the effects of the morphologic disorders on cardiac dynamics are not yet clear [3, 8–10, 13]. Whether ventricular function in HOCM is disturbed ...

Influence of Nitroglycerin on Aortic Compliance, Capacity of the Windkessel, and Peripheral Resistance
In recent years it has been established that the effect of nitroglycerin (NTG) is mainly related to its extracardial factors. Most of the investigators found a reduction only in preload [2, 9, 12], while other...

Effects of Nitroglycerin on Left Ventricular and Myocardial Function in Aortic Stenosis
The beneficial effects of nitroglycerin (NTG) in ischemic heart disease are due mainly to a reduction in preload [1, 2] and, consequently, in myocardial oxygen demands [5, 8]. However, both a secondary effect ...

Videodensitometric Measurement of Coronary Flow
The first attempts to measure coronary artery flow velocities using densitometry were done nearly 15 years ago (Rutishauser et al. 1967, 1970a, 1970b; Smith et al. 1971). Methodological improvements have been ...

Recombinant Tissue-Type Plasminogen Activator in the Treatment of Myocardial Infarction
Recent studies have reported recombinant tissue-type plasminogen activator (rt-PA) to be more effective in early recanalization of infarct-related coronary artery occlusion than the conventional non-fibrin-spe...

Plasma concentrations of atrial natriuretic peptide (α- h-ANP 1–28) during exercise and relationship to hemodynamic parameters in man
To elucidate the diagnostic value of Atrial Natriuretic Peptide (ANP), ANP plasma concentrations were determined by radioimmunoassay in 15 patients with coronary or valvular heart diseases who were to undergo ...
