Association of coronary angiographic lesions and mortality in patients over 80 years with NSTEMI

OBJECTIVE: Coronary angiography (CA) and percutaneous coronary intervention (PCI) is of great importance during non-ST-segment elevation myocardial infarction (NSTEMI) management. Coronary artery lesions and their association to mortality in elderly patients with NSTEMI was investigated. METHODS: Pa...

Sumario:OBJECTIVE: Coronary angiography (CA) and percutaneous coronary intervention (PCI) is of great importance during non-ST-segment elevation myocardial infarction (NSTEMI) management. Coronary artery lesions and their association to mortality in elderly patients with NSTEMI was investigated. METHODS: Patients >80 years of age who underwent CA at index NSTEMI during 2011–2014 were included. Data were collected from the Swedish Coronary Angiography and Angioplasty Registry and Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies registries. Coronary lesions were categorised into; one vessel disease (1VD), multi-vessel disease (MVD) and left main disease (LMD) and 0%–49% stenosis grade were considered as controls. Cox regression was used to estimate HRs for all-cause mortality associated with coronary lesions. Survival benefit was determined after PCI and in relation to if revascularisation was complete or incomplete and any complications in the Cath lab was assessed. RESULTS: Five thousand seven hundred and seventy patients with history of CA and PCI were included, 10% had normal coronary arteries, 26% had 1VD, 50% MVD and 14% LMD. Mortality was higher in patients with 1VD, MVD and LMD: HR 1.8 (1.3–2.5), HR 2.2 (1.6–3.0) and HR 2.8 (2.1–3.9), respectively. PCI were treated in 84% of 1VD, 73% MVD, and 54% in LMD. Survival was higher with PCI HR 0.85 (0.73–0.99). MVD had lower adjusted mortality HR 0.71 (0.58–0.87) compared with patients with MVD who did not undergo PCI. Complications and mortality were higher in patients with LMD both during CA and PCI, HR 2.9 (1.1–7.6) and HR 4.5 (1.6–12.5). CONCLUSION: Coronary lesions (>50% stenosis) are strong predictors of mortality in elderly patients with NSTEMI. MVD is common and PCI treatment is associated with increased survival.
