A double aorto-coronary bypass procedure performed in 2 cases, one with a Prinzmetal`s variant angina and the other with an unstable angina, is presented. The patient with a Prinzmetal`s angina who had a high-grade obstruction of the left anterior descending and the right coronary system showed a marked postoperative improvement with complete disappearance of anginal pain. The other patient with unstable angina had obstruction of the left anterior descending as well as a marginal branch of the left circumflex artery. Following bypass of these vessels, the patient did well during the immediate postoperative period. However, he developed hypotension in the recovery room and died 6 hours postoperatively, in spite of an intensive effort at resuscitation. The most likely cause of death in this patient is a myocardial infarction.

In selected patients with occlusive lesions of coronary arteries, aortocoronary bypass grafting has been effective in reducing anginal symptoms and in increasing the patients` longevity. Between May, 1977, and December, 1983, 41 patients with coronary occlusive disease received aortocoronary bypass surgery at Yonsei University Medical Center in Seoul. Thirty-three were male and 8 were female. Their ages ranged from 33 to 70 years [average 531.6 years]. Of the 41 patients, 11 suffered from stable angina, 30 suffered from unstable angina and 4 suffered from a variant type of angina. Eleven patients had 1 diseased vessel, 11 patients had 2 diseased vessels, 19 patients had 3 diseased vessels, and 5 patients had a diseased left main coronary artery. A single graft was placed in 5 patients, a double graft was placed in 17 patients, a triple graft was placed in 11 patients and a quadruple graft was placed in 8 patients. Nineteen patients received a sequential graft [40 sites of 20 vessels]. The average internal diameter of the grafted distal coronary artery was 2.380.15, 1.630.13 mm on the left side and 3.200.20, 1.830.21 mm on the right side. Two operative deaths occurred in the early years of our experience. The mortality rate was 4.87% and there were no late deaths. Of the 39 survivors, 30 [76.9%] were Functional Class I [free of symptoms without medication], 7 [17.9%] were Functional Class II and only 2[5.2%] were Functional Class III during the follow up period [653.75 patient-months]. On the basis of this experience, we conclude that coronary artery occlusive disease is occurring in increasing numbers in Korea. Therefore, a concerted effort is needed to detect this disease and to manage the increasing number of patients suffering from it.

Background: Health care services effort to provide alternative cardiac rehabilitation (CR) models to serve patients according to their preferences and needs. So, the present study aimed to assess and compare the effects of hospital-based and hybrid CR programs on chest pain intensity and discomfort in cardiac surgery patients. Methods: In this prospective study, 110 cardiac surgery patients were invited to the CR department of a hospital in the western part of Iran between March and July 2016. Patients were divided into two groups: hospital-based and hybrid CR. The hospital-based program included 26 sessions, and the hybrid program included 10 training sessions and exercise. The Brief Pain Inventory and Pain Discomfort Scale were used as research instrument, and data were analyzed using the paired t-test and ANCOVA. Results: The results indicated that both hospital-based and hybrid CR are effective in reducing the chest pain intensity and discomfort of cardiac surgery patients (P < 0.05). In addition, the comparison of scores before and after treatment using ANCOVA shows that no significant differences were observed between the two programs (P > 0.05). Conclusions: Traditional hospital-based CR delivery is still the first choice for treatment in developing countries. However, hybrid CR is as effective as a hospital-based program in reducing pain components and it includes only 38% of the total cost in comparison to hospital-based delivery. So, we recommend using hybrid CR according with the recommendations of American Heart Association about using CR for the management of angina symptoms.
