Scientists decided to investigate if procedures like angioplasty and stent placement following heart attack would help in preventing another one. Although their hopes were high up, the statistics showed no benefits from these procedures.

This study is beneficial because it helped in realizing what’s really important and that angioplasties in such patient would be superfluous and necessary.
The study was rated as negative as it failed to show benefits. Such negative studies are as important as the positive ones as they may aid in improving the efficiency of health care.

For the time being, it is a practice to open blocked arteries in the first 12 hours after a heart attack. However, many angioplasties are being done even after that time window closed. Such practice is unnecessary as it carries no benefits to the patients.

The study included 2,166 stable patients with 100 percent blockage of the heart attack-related artery who have been given randomized to receive either angioplasty and stenting with drug therapy or drug therapy alone. Scientists thought that these procedures would cut their risks of another heart attack, heart failure and death by 25%. However, no statistically significant difference between the two groups in rates of repeat heart attacks, heart failure or death was found.

Since these medical procedures showed no benefits, health experts are turning to secondary prevention such as stopping smoking, losing weight and controlling diabetes and high blood pressure.
