Clinical characteristics and survival experience of out-of-hospital cardiac arrest victims without coronary heart disease.
Of 270 patients successfully resuscitated from out-of-hospital cardiac arrest, 16% had no evidence of coronary heart disease. In these 43 patients, other forms of heart disease were found in 81% (35/43): cardiomyopathy in 18 patients, valvular disease in six, congenital heart disease in two, and primary arrhythmia in nine. Seven patients had evidence of only pulmonary disease and one had pancreatitis as his precipitating event. Nineteen of the 43 patients (44%) had serum potassium less than 3.6 mEq l-1 in the initial blood sample after cardiac arrest. One- and two-year mortalities were 30% and 43%, respectively, for the group, which is similar to one-year (20%) and two-year (35%) mortalities of the 227 resuscitated patients with coronary heart disease. Patients who survive a sudden death experience and who have no evidence of coronary artery disease are a unique but heterogeneous group who usually have identifiable cardiac or pulmonary disease.
