Coronary Artery Bypass Grafting Versus Percutaneous Coronary Intervention in Patients With Non-ST-Elevation Myocardial Infarction and Left Main or Multivessel Coronary Disease.

Current recommendations on the optimal revascularization strategy in Non-ST-elevation myocardial infarction (NSTEMI) with left main (LM) or multivessel coronary disease (MVD) are based upon randomized clinical trials conducted in stable coronary artery disease. In a real-world contemporary observational registry, we compared the long-term outcome of NSTEMI patients with LM/MVD (n = 1,104) submitted to coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), or optimized medical therapy (OMT). The primary end point was 5-year all-cause mortality. Results were assessed in the entire population (CABG 289, PCI 399, and OMT 416) and in a propensity score-matched cohort of CABG (n = 159) and PCI (n = 159). Crude 5-year mortality rates in CABG and PCI were 25.3% versus 29.6%, respectively (unadjusted hazard ratio [HR] 1.2; 95% confidence intervals [CI] 0.9 to 1.6; p = 0.212); OMT, however, was associated with a twofold higher risk of mortality when compared with any revascularization strategy (unadjusted HR 2.0; 95% CI 1.7 to 2.5; p < 0.001). After propensity score-matching and multivariate analysis, there was a trend toward a higher incidence of the primary end point in patients who underwent PCI versus CABG (31% vs 21%; adjusted HR 1.52; 95% CI 0.93 to 2.50; p = 0.094). This was a consistent finding over subgroups deemed clinically relevant, such as in patients with LM or proximal left anterior descending disease, SYNergy between percutaneous coronary intervention with TAXus ≥23 and left ventricle ejection fraction <40%. In conclusion, in a real-world cohort of NSTEMI patients with LM/MVD, those selected for OMT had a dire outcome. Although adjusted 5-year mortality was statistically similar between revascularization strategies, there was a trend favoring CABG, which might be the preferred option in LM, proximal LAD, SYNergy between percutaneous coronary intervention with TAXus ≥23, and left ventricle ejection fraction <40% subgroups.

Acute coronary syndrome in the oncology patient: An avoidable event? / Síndrome coronária aguda em doente oncológico: um problema evitável?

5-Fluorouracil is a first-line agent in several cancer-therapy regimens. Cardiotoxicity is common, with coronary artery disease being an important risk factor. We report the case of an acute coronary syndrome presumably induced by 5-FU, in a patient with previously unknown and asymptomatic coronary artery disease, with an estimated intermediate risk for cardiovascular events. Pre-chemotherapy risk evaluation and optimal patient care are still not standardized in this clinical scenario.
