Abstract

A study is conducted to assess trends in early revascularization and mortality for patients with cardiogenic shock complicating acute myocardial infarction (AMI) and to determine whether the national guidelines affect revascularization rates. It is concluded that the use of percutaneous coronary intervention (PCI) for patients with cardiogenic shock was associated with improved survival in a large group of hospitals with revascularization capability.

19. The volume of primary angioplasty procedures and survival after acute myocardial infarction

Abstract

Heart attack patients who are treated at hospitals that do many angioplasty procedures have lower mortality rates while they are in the hospital. This was the conclusion of researchers who analyzed mortality rates among heart attack patients treated at 450 hospitals that perform angioplasty and 516 hospitals that use thrombolytic drugs. Both of these treatments are used to open up blocked arteries. The in-hospital mortality rate was 28% lower in hospitals that did the most angioplasties compared to those that did the fewest. This reduction in mortality was not seen in the hospitals that only used thrombolytic drugs.

23. Sex-based differences in early mortality after myocardial infarction

Abstract

Young women who have a heart attack have a higher mortality rate than men their age. This was the conclusion of a study of 384,878 heart attack patients between 30 and 89 years old, 155,565 of whom were women. During their hospital stay, the mortality rate in the women less than 50 years old was more than twice the rate in men the same age. Mortality rates in young women were still higher after adjusting for the serious of the heart attack and the care the patients received.

27. Absence of association between insurance copayments and delays in seeking emergency care among patients with myocardial infarction

Abstract

Having to make a copayment may not necessarily reduce the use of emergency medical services. Researchers analyzed the hospital records of 1,331 people in an HMO who came to the emergency room with the signs and symptoms of a heart attack. Of these, 602 were required to make a copayment and 729 were not. A copayment requirement did not cause any significant delays in seeking medical care even after adjusting for other factors that might influence emergency room visits. Some studies have shown that copayment requirements lead to reduced use of emergency medical services.

30. A comparison of thrombolytic therapy with primary coronary angioplasty for acute myocardial infarction

Subjects

Abstract

Treatment of acute heart attack with clot-dissolving drugs or angioplasty appears to be equally effective. Angioplasty and drugs called thrombolytics are both used to open blocked arteries. Researchers studied short-term and long-term mortality in 1,050 heart attack patients treated with angioplasty and 2,095 heart attack patients treated with thrombolytics. There was no difference in mortality between the groups in the short- or long-term. Those who received angioplasty used more resources and incurred higher costs. Thrombolytics are easy to administer and do not require technical skill.

38. The association between on-site cardiac catheterization facilities and the use of coronary angiography after acute myocardial infarction

Abstract

Patients treated in hospitals with cardiac catheterization facilities were three times more likely to have coronary angiography performed after a heart attack than patients admitted to a hospital without those facilities. Coronary angiography is a diagnostic technique that uses X-rays to visualize the heart and blood vessels after the injection of a contrast medium into the veins. A review of the records of 5,867 patients admitted to 19 Seattle, WA, hospitals for treatment of heart attacks evaluated the likelihood that patients would have angiography performed. A further analysis of 614 patients treated by doctors who worked at both hospitals with the catheterization facilities and those without indicated that the doctors performed the procedure on 73% of their patients at hospitals with on-site facilities. The procedure was only performed on 47% of those admitted to hospitals without cardiac catheterization facilities. There was no association between on-site facilities and in-hospital mortality rates.
