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

Article 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.

Prevalence, Clinical Characteristics, and Mortality Among Patients With Myocardial Infarction Presenting Without Chest Pain

Article Abstract:

Many people who have a heart attack do not have chest pain and this can cause delays in their treatment. In a study of 434,877 patients treated for a heart attack at 1,674 US hospitals over a four-year period, one-third did not have chest pain. Patients without chest pain were more likely to be women, diabetics, or older than those with chest pain. They also waited longer to get to the hospital, were less likely to receive effective treatments, and more likely to die than patients with chest pain.

Relation Between Hospital Primary Angioplasty Volume and Mortality for Patients With Acute MI Treated With Primary Angioplasty vs Thrombolytic Therapy

Article Abstract:

Heart attack patients treated with angioplasty are more likely to survive than those treated with thrombolytic drugs, but only if they are treated at hospitals with doctors who are experienced in angioplasty. This was the conclusion of a study of 62,299 patients who received either one of the treatments, both of which are used to open blocked coronary arteries.
