Functional benefits following coronary artery bypass graft surgery

While some studies of patients who undergo cardiac surgery have included such outcome measures as amounts of symptom reduction and rates of resumption of employment, little attention has been focused on the extent to which these patients have experienced the simple, yet very important, broad range of functional benefits that might be anticipated by clinicians to result from operation. The present report seeks to document the extent of improvement that does exist in terms of physical, sexual, and social-role functioning. In a cohort of 340 patients (age, 32 to 69 years) studied before and six months after coronary artery bypass operation, improvements were noted in each of three dimensions of functional benefit: physical functioning (fewer total activity restrictions or incapacitated days per month), sexual functioning (through increased energy and desire and decreased pain and worry), and role functions (ability to work, social participation, and pursuit of hobbies). Further improvements might be anticipated with additional months of recovery

The Implantable Cardioverter‐Defibrillator: Clinical Results

To evaluate the effectiveness of the automatic implantable cardioverter‐defibrillator (AICD), a 7‐year experience, from 1983–1990, was reviewed. A total of 111 patients received an AICD device. Their ages ranged between 8 and 83 years. Mean age was 63.9 years. There were 91 men and 20 women. Eighty of the patients received the AICD following an out‐of‐hospital cardiac arrest, white 32 were suffering from intermittent symptomatic ventricular tachycardia. The underlying etiology in 97 patients (87%) was ischemic coronary artery disease, in 11 patients (10%) dilated cardiomyopathy, and in 3 patients (3%) idiopathic ventricular fibrillation. Mean ejection fraction was 33.2%. Implantation of the AICD was performed via a left thoracotomy in 39 patients, median sternotomy in 49 patients and subxiphoidsubcostal approach in 23 patients. In‐hospital mortality occurred in one patient who suffered an acute myocardial infarction 4 hours postoperatively. Out‐of‐hospital mortality was observed in 19 patients. There were two arrhythmic deaths. Follow‐up was available for 107 patients. Mean follow‐up was 33.1 months. Sixty‐six patients (62%) had AICD shocks. The initial appropriate shocks occurred during the first postimplantation year in 91% of the patients. In 53 of the survivors, initial AICD shocks took place within 4.4 ± 4.7 months from implantation. Thirteen of the 20 patients who died had received appropriate AICD shocks. In these patients, the time between implantation and first shock was 2.7 ± 3.6 months whereas the time between implantation and death was 11.3 ± 10.3 months (NS). We conclude that the AICD is effective in converting ventricular tachyarrhythmias and prolongs survival
