Abstract
BACKGROUND: Elevated heart rate (HR) is associated with mortality in a number of heart diseases. We examined the long-term prognostic significance of HR at discharge in a contemporary population of patients with stable angina (SAP), non-ST-segment elevation acute coronary syndromes (NSTE-ACS), and ST-segment elevation myocardial infarction (STEMI) revascularized with percutaneous coronary intervention (PCI).
METHODS: Patients from the BASKET-PROVE trial, an 11-center randomized all-comers trial comparing bare-metal and drug-eluting stenting in large coronary vessels, were included. Discharge HR was determined from a resting ECG. Long-term outcomes (7days to 2years) were evaluated for all-cause mortality and cardiovascular death and non-fatal myocardial infarction.
RESULTS: A total of 2029 patients with sinus rhythm were included, 722 (35.6%) SAP, 647 (31.9%) NSTE-ACS, and 660 (32.5%) STEMI. Elevated discharge HR was associated significantly with all-cause mortality: when compared to a reference of <60beats per minute (bpm), the adjusted hazard ratios were (95% CI) 4.5 (1.5-13.5, p=0.006) for 60-69bpm, 3.8 (1.2-11.9, p=0.022) for 70-79bpm, 4.3 (1.2-15.6, p=0.025) for 80-89bpm, and 16.9 (5.2-55.0, p<0.001) for >90bpm. For cardiovascular death/myocardial infarction, a discharge HR >90bpm was associated with a hazard ratio of 6.2 (2.5-15.5, p<0.001) compared to a HR <60bpm. No interaction was found for disease presentation, diabetes or betablocker use.
CONCLUSION: In patients revascularized with PCI for stable angina or acute coronary syndromes an elevated discharge HR was independently associated with poor prognosis. Conversely, a HR <60bpm at discharge was associated with a good long-term prognosis irrespective of indication for PCI.
