Key result
Older age (>60 years, P<0.05), cardiomegaly (P<0.01), and pulmonary venous congestion (P<0.05) were associated with significantly increased long-term mortality in patients with unstable angina.
Cohort (n=158)
No
Unstable angina carries a significant acute and long-term mortality risk, with worse prognosis observed in older patients and those with signs of heart failure.
No takes yet. Share an insight, caveat, or question.
Supports risk stratification by age and heart failure signs in unstable angina; extends prior cohorts but leaves open therapeutic implications.
Heng et al. (1976) conducted a cohort in unstable angina (n=158). Older age (>60 years, P<0.05), cardiomegaly (P<0.01), and pulmonary venous congestion (P<0.05) were associated with significantly increased long-term mortality in patients with unstable angina.
