Key result
In male patients awaiting PTCA, unstable angina increased adverse events vs stable angina (57% vs 17%, P=0.0001), with a relative risk of 6.9 (P<0.02) when combined with increased triglycerides.
Population
219 consecutive male patients on a waiting list for routine percutaneous transluminal coronary angioplasty.
Design
Cohort
Follow-up
median 8 months (range 3-25 months)

Unstable angina with elevated triglycerides signals higher pre-PTCA risk in men; leaves open whether targeted strategies improve outcomes.
Cohort (n=219)
Absolute Event Rate: 57% vs 17%
p-value: p=0.0001
Patients awaiting routine PTCA face a 23% risk of adverse coronary events, which is significantly higher in younger patients and those presenting with unstable angina and elevated plasma triglycerides.
Chester et al. (1995) conducted a cohort in Awaiting routine percutaneous transluminal coronary angioplasty (PTCA) (n=219). Unstable angina vs. Stable angina was evaluated on Development of myocardial infarction, unstable angina, or angiographic total coronary occlusion (p=0.0001). In male patients awaiting PTCA, unstable angina increased adverse events vs stable angina (57% vs 17%, P=0.0001), with a relative risk of 6.9 (P<0.02) when combined with increased triglycerides.
