Figure 1 Adjusted Hazard Ratios (95% Confidence Intervals) for Adverse Outcomes
Multivariable Cox proportional hazards models were used to determine the independent prognostic value of left ventricular mass index (LVMi), LV mass/end-diastolic volume (EDV), and relative wall thickness (RWT). The models were adjusted for age (years), primary percutaneous transluminal coronary angioplasty, atrial fibrillation complicating myocardial infarction (MI), history of diabetes, history of hypertension, prior MI, Killip class, history of congestive heart failure (HF), new left bundle branch block, history of angina, LV ejection fraction, estimated glomerular filtration rate, and a history of chronic obstructive pulmonary disease. Each 10 g/m2 increase in LVMi (A), 0.1-U (10%) increase in LV mass to end-diastolic volume ratio (B), and 0.1-U (10%) increase in RWT (C) were independently associated with increased risk for death, cardiovascular (CV) death, and death or heart failure hospitalization (each p < 0.001). Echocardiographically determined LV mass and RWT are significant independent predictors of increased cardiovascular morbidity and mortality in high-risk post-MI patients warranting their routine assessment.
