-
NS, not significant (significance is when p < 0.05); *Number of epicardial coronary arteries with stenosis > 70%; †LV score, the sum of scores given for wall motion to the five segments of the left ventricle on the RAO projection of the LV angiogram; ‡LVEDP, left ventricular end diastolic pressure, measured through an intraventricular pigtail catheter at the time of the cardiac catheterisation; §Smoking, patients who are current smokers or exsmokers; ¶Hypercholesterolaemia, defined as total serum cholesterol > 5.2 mmol/l; **Diabetes, both insulin dependent and non-insulin dependent diabetes mellitus according to World Health Organization criteria irrespective of the treatment modality; ††Hypertension, either blood pressure > 140/90 mm Hg at the time of catheterisation or in the past, whether on treatment.
