Clinical outcome in patients with intermediate stenosis of left anterior descending coronary artery after deferral of revascularization on the basis of noninvasive coronary flow reserve measurement.

Background: Several reports suggest that noninvasive measurements of coronary flow reserve (CFR) by use of echocardiography may support decision making in intermediate stenosis of the left anterior descending coronary artery (LAD). The aim of the present study was therefore to analyze the clinical outcome in patients with intermediate stenosis of LAD after deferral of coronary revascularization on the basis of noninvasive CFR measurement.

Methods: the study population included 280 patients with intermediate LAD stenosis (50-70% by angiography) (62.

[Early detection of heart involvement using serial cardiologic controls in the follow-up of patients with AIDS].

New effective therapies have been producing longer survival times for HIV-patients. Thus non-infectious complications of late stage of HIV infection (such as the development of left ventricular dysfunction) have emerged; in fact cardiac involvement has been identified frequently at autopsy and is described in 80% of patients with acquired immunodeficiency syndrome (AIDS) as an evidence of the virus cardiotrophism, while clinical findings of left ventricular dysfunction were only detected in about 15% of the patients. It is possible that the development of heart failure had been underestimated in those years; in fact signs and symptoms of cardiac involvement had been often misinterpreted as the results of non cardiac causes (pulmonary failure or infections) also determining a delay in the beginning of cardiac therapy.

[The efficacy of creatine phosphate in the treatment of patients with heart failure. Its echographic evaluation after acute and protracted treatment].

The hemodynamic effects of acute and long-term administration of creatine phosphate were studied in 23 patients with heart failure (NYHA classes II and III) under stabilized treatment. Acute creatine phosphate (5 g i.v.

[Clinical-echocardiography of 210 HIV-Ab positive patients: retrospective study].

Through the retrospective study of 210 HIV Ab+ patients in different disease's stages, recovered in the "D. Cotugno-Naples" hospital during the period February 1989-February 1991, the authors have valued the prevalence of cardiological alterations underlined by ecocardiograph. Pericardial pouring has been observed in four patients out of thirty, belonged to stages II, III and ARC.
