Furthermore, the following baseline data were registered: age, gender, hypertension (defined as being treated with blood pressure lowering medication, or being diagnosed as having hypertension during hospital stay, i.e. systolic blood pressure > 140 mmHg, or diastolic blood pressure > 90 mmHg), hypercholesterolemia (defined as being treated with lipid lowering medication, or having an in-hospital fasting total cholesterol of ≥ 5 mmol/L (192 mg/dL), or LDL ≥ 3 mmol/L (116 mg/dL)), smoking status, family history of coronary heart disease, diabetes (defined as being treated with an anti-diabetic agent, or having an in-hospital fasting plasma glucose ≥ 6.1 mmol/L, or a non-fasting plasma glucose ≥ 11.1 mmol/L), prior coronary vessel disease, and height and weight. Medication status was recorded at admission, at discharge, and at the 30-day follow up. Left ventricular ejection fraction (LVEF) was assessed during hospital stay by echocardiography using the 16 standard segments model (28).
