View larger version (29K): [in a new window]   Figure 1 Multivariate risk ratios for each of the four risk factors and age. The bars represent the upper and lower 95% confidence intervals. Ratios >1 indicate a positive association with SD. Abnormal exercise blood pressure pertains only to patients <40 years old. MLVWT = maximal left ventricular wall thickness; FH = family history of SD; Abn BP = abnormal exercise blood pressure response in patients <40 years old; RF = risk factors.

The majority of deaths were sudden, and the greatest proportion occurred in patients with multiple risk factors. CCF = congestive cardiac failure; Tx = cardiac transplant.
