Clinical course of isolated stable angina due to coronary heart disease
European Heart Journal , Volume 28 - Issue 16 p. 1928- 1935
Aims: To describe the clinical course of patients with stable angina due to coronary heart disease without a history of cardiovascular (CV) events or revascularization (isolated angina). Methods and results: Of 7665 patients in a trial comparing long-acting nifedipine with placebo, 2170 (28%) had isolated angina. During a mean follow-up of 4.9 years, 147 of these died (1.4/100 patient-years), while 761 (8.7/100 patient-years) either died, or had a cardiac event or procedure. The first event was death in 82, myocardial infarction or heart failure in 112, coronary revascularization in 171, and chest pain requiring hospitalization in 396. Six hundred and twelve patients (6.8/100 patient-years) underwent coronary angiography (CAG), followed by revascularization in 371. Sixty-eight of 262 deaths or major cardiac events were preceded by chest pain requiring hospitalization or revascularization. Event-rates after CAG were higher than before. The stroke rate was 0.7/100 patient-years (75 patients). Conclusion: Patients with stable isolated angina have low rates of death and major cardiac events, but relatively high rates of chest pain requiring hospitalization despite contemporary management. Since the majority of deaths and major CV clinical events are not preceded by clear warning symptoms, the main clinical implication is that measures to prevent such events must target all patients.
