The risk of sudden death is higher in younger patients with severe hypertrophy (wall thickness 20-30mm), LVOT gradient higher than 50 mmHg, LA dilatation (greater than 45 mm), reduction in blood pressure with exercise, personal history and family history of syncope.
In the pressure-volume loop below, cardiac work is best represented by: the area of the curve the slope of the line from points C to D the distance of the line from points C to D the slope of a line from points A to D .. .. ... .... ... .... .... .... In the pressure-volume loop below, cardiac work is best represented by: the area of the curve Cardiac work is the product of pressure and volume and is linearly related to myocardial oxygen consumption. Cardiac work is best represented by the area of the curve of a pressure-volume loop.
