ESH: Factors influencing prognosis Risk factors for cardiovascular disease used for stratification Levels of systolic & diastolic BP Men > 55 years Women > 65 years Smoking Dyslipidaemia (total cholesterol >6.5 mmol/l, >250 mg/dl *, or LDL-cholesterol > 4.0 mmol/l, >155 mg/dl*, or HDLcholesterol M < 1.0, W< 1.2 mmol/l, M<40,W <48 mg/dl) Family history of premature cardiovascular disease (at age < 55 years M, < 65 years W) Abdominal obesity (abdominal circumference M 102 cm, W 88 cm) C-reactive protein 1 mg/dl Target organ damage (TOD) Left ventricular hypertrophy (electrocardiogram: Sokolow– Lyons > 38 mm; Cornell > 2440 mm* ms; echocardiogram:LVMI M 125, W 110 g/m2) Ultrasound evidence of arterial wall thickening (carotid IMT 0.9 mm) or atherosclerotic plaque Slight increase in serum creatinine (M 115–133, W 107– 124 μmol/l; M 1.3–1.5, W 1.2–1.4 mg/dl) Microalbuminuria (30–300 mg/24 h; albumin– creatinine ratio M 22, W 31 mg/g;M 2.5, W 3.5 mg/mmol) Diabetes mellitus Associated clinical conditions (ACC) Fasting plasma glucose 7.0 mmol/l Cerebrovascular disease: ischaemic stroke; cerebral haemorrhage; transient ischaemic attack Heart disease: myocardial infarction; angina; coronary revascularization; congestive heart failure Renal disease: diabetic nephropathy; renal impairment (126 mg/dl) Postprandial plasma glucose > 11.0 mmol/l (198 mg/dl) (serum creatinine M >133, W >124 μmol/l; M >1.5, W > 1.4 mg/dl) proteinuria (>300 mg/24 h) Peripheral vascular disease Advanced retinopathy: haemorrhages or exudates, papilloedema M, men; W, women; LDL, low-density lipoprotein; HDL, high-density lipoprotein; LVMI, left ventricular mass index; IMT, intima-media thickness. Lower levels of total and LDL-cholesterol are known to delineate increased risk, but they were not used in the stratification • Vascular disease—and CAD in particular— is the leading cause of death in the US and other Western nations • By 2020, cardiovascular disease will become the most common cause of death worldwide • Due to the high initial mortality of vascular disease, the target of clinical practice must be aggressive risk factor management Coronary Artery Disease (CAD): The Diagnosis Often Comes Too Late Atherosclerosis Begins in Childhood (Adapted from Berenson et al.) Berenson GS et al, N Engl J Med, 1998. Most Myocardial Infarctions Are Caused by Low-Grade Stenoses Pooled data from 4 studies: Ambrose et al, 1988; Little et al, 1988; Nobuyoshi et al, 1991; and Giroud et al, 1992. (Adapted from Falk et al.) Falk E et al, Circulation, 1995. CAD: Not Just a Lipid Disease • Half of all MIs occur in normolipidemic patients • Smoking Accounts for 200,000 cardiovascular deaths annually • Diabetes Affects 16 million Americans—and is growing • Hypertension Confers as much risk for MI as smoking or dyslipidemia – Systolic hypertension is an even greater indicator of CAD risk than diastolic hypertension Braunwald E, N Engl J Med, 1997; Grundy SM et al, Circulation, 1998; The Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure and the National High Blood Pressure Education Program Coordinating Committee, Arch Intern Med, 1997.
