Effects of intravenous verapamil on left ventricular systolic function and diastolic filling dynamics in patients with coronary artery disease: Analysis of intramyocardial markers
Left ventricular (LV) intramyocardial markers (MM) were used to study the effects of intravenous verapamil on LV pump function and diastolic filling dynamics. Verapamil (0.1 mg/kg bolus followed by 0.005 mg/kg...

Effect of Nisoldipine and Nitroglycerin on Myocardial Ischemia and Dysfunction During Coronary Angioplasty
The degree to which anti-ischemic agents influence myocardial ischemia and ventricular dysfunction during coronary angioplasty (PTCA) is unclear. Therefore, the effects of 0.05 mg intracoronary (i.c.) nisoldip...

Effect of prolonged balloon inflations on hemodynamics and coronary flow with respect to balloon position in patients undergoing coronary angioplasty
It is well-known from numerous animal studies that the abrupt closure of a major coronary artery can cause a rapid drop in regional blood flow to near O-values and a subsequent marked deterioration of myocardi...

The influence of Ca2+-entry blockers on hemodynamics and coronary blood flow, and its importance for the treatment of angina pectoris
The way calcium-entry blocking agents, especially nifedipine, act in angina pectoris, is a complex one and is still not completely understood. Nifedipine, through its profound relaxing effect on vascular smoot...
