BACKGROUND Ischemic heart disease is the leading cause of death in the world and angina is its cardinal manifestation. OBJECTIVE To determine the prevalence of angina and possible angina and its distribution by main demographic and socioeconomic characteristics among adults 40 years of age or older. METHODS This is a population-based, cross-sectional study featuring residents of the urban a...

Atrial pacing to the point of angina or up to a maximum rate of 166/min was carried out in 37 patients during coronary angiography. In 9 patients with normal coronary arteries both the right and left ventricular end-diastolic pressures fell remained steady with increasing heart rate. The same response was observed in 14 patients with angiographically proven coronary artery disease. In the rema...

Background and aim: New modalities in the treatment of end-stage renal disease (ESRD) patients have increased their life expectancy and quality of life. A wide range of cutaneous manifestations are seen in ESRD patients. This study was conducted to determine the prevalence of cutaneous manifestations in ESRD patients on maintenance hemodialysis in the dialysis department of Imam Khomeini ...

Myocardial substrate extraction, coronary sinus flow, left ventricular pressure, and cardiac output were measured in 11 patients with angina pectoris at three pacing rates before and after atenolol (0.2 mg/kg). Left ventricular pressures, and the product of systolic pressure time index and heart rate did not change, but max dP/dt and KV max fell after atenolol. Only at the lowest pacing rate di...

The increased left ventricular end-diastolic pressure associated with myocardial ischemia was studied in 19 patients at cardiac catheterization. Single plane left ventriculograms were performed using high fedelity micromanometer tipped catheters before and immediately following rapid atrial pacing. Left ventricular diastolic properties were evaluated by constructing diastolic pressure-volume cu...

We assessed the long-term outcomes of enhanced external counterpulsation in relieving angina and improving the quality of life in a large cohort of patients with chronic angina pectoris. Seventy-three percent had a reduction by > or =1 angina class at the end of treatment, and 50% reported an improvement in the quality-of-life assessment after enhanced external counterpulsation; these results w...
