The linearity and sensitivity of the end-systolic pressure-volume (P-Ves) relation to the inotropic state of the left ventricle were investigated in 11 patients with coronary heart disease and one patient with congestive cardiomyopathy. To minimize autonomic reflex responses, propranolol, 0.15 mg/kg, and atropine, 1 mg, were administered i.v. at the(More)
The clinical outcome of 52 consecutive patients with hypertrophic cardiomyopathy who developed paroxysmal (less than 1 week) or established (greater than or equal to 1 week) atrial fibrillation between 1960 and 1985 was examined retrospectively and compared with that of a matched group of patients with hypertrophic cardiomyopathy and sinus rhythm. Follow-up(More)
AIMS This report describes the baseline characteristics of patients in the Reduction of Events with Darbepoetin alfa in Heart Failure trial (RED-HF) which is testing the hypothesis that anaemia correction with darbepoetin alfa will reduce the composite endpoint of death from any cause or hospital admission for worsening heart failure, and improve other(More)
OBJECTIVE To determine the prognosis in patients with diphtherial myocarditis and bradyarrhythmias and to assess the results of ventricular pacing in those with third degree atrioventricular block. DESIGN Case series. SETTING Referral department of cardiology in a teaching hospital. PATIENTS Twenty four out of 46 patients admitted with diphtherial(More)
The benefits of digoxin in patients with atrial fibrillation may be reduced due to its limited effect on atrioventricular conduction. The aim of this work was to compare digoxin and atenolol on functional class, resting and exercise heart rate and exercise capacity in patients with atrial fibrillation. Thirteen subjects with this condition, normal(More)
The analysis of the post-extrasystolic (PES) beat, which follows an at random elicited extrasystole, has been used frequently in clinical studies for the evaluation of the functional reserve of the left ventricle. Therefore, the relation between the PES potentiation and the normalized coupling interval (RR'/RR) and the normalized length of the PES pause(More)
BACKGROUND From January 2000 to June 2002, the first Chilean registry of unstable angina was carried out, with the participation of 15 hospitals. AIM To report the clinical and demographic features of 600 patients with unstable angina, their risk profile and prognosis. MATERIAL AND METHODS The inclusion criteria for this prospective registry were a(More)
BACKGROUND Mortality due to infective endocarditis (IE) in Chile is close to 30%. AIM To report the experience with patients admitted with the diagnosis of IE in a regional tertiary hospital. MATERIAL AND METHODS Retrospective study of 107 patients aged 50 ± 16 years (75% males) discharged with a definitive diagnosis of IE according to modified DUKE(More)
