Polypill Was Effective Among People With Heart Attacks

A cheap, once-a-day pill combining aspirin with drugs that lower blood pressure and cholesterol cuts cardiovascular disease as a whole by a third, and heart attacks by more than half, researchers report in The Lancet. In clinical trials, the polypill was especially effective among people with no history of cardiovascular disease; reducing the number of severe events by 40%. For those with a history of heart problems and strokes; the drug combo was only half as effective.

Heart attacks across cohort

The polypill concept was first propose more than 20 years ago as a simpler; so cost effective approach to treating cardiovascular disease. Currently, patients are typically prescribe one or more drugs to lower blood pressure along with a statin; which holds lipids such as fatty acids in check. Aspirin, an analgesic, has blood thinning properties.

“The more tablets people have to take, the less they comply in the long term,” noted Kausik Ray, a professor in public health and Imperial College London not involve in the study. About a third of patients stop taking their meds as early as 90 days after a heart attack, according to earlier research. But despite its obvious potential, the polypill had yet to be test on a large number of people over a long period of time.

Scientists led by Reza Malekzadeh from the Tehran University of Medical Sciences recruit nearly 7,000 men and women; age 50 to 75, living in rural Golestan, a province in Iran. The participants were divide into two groups. While one was a control arm, the other also got a daily polypill from 2011 to 2013. Doctors monitor compliance with the drug regimen; also then tallied the number of strokes and heart attacks across each cohort over the next five years.

Polypill with clinical benefits

Crucially, adherence was significantly higher with the all in one pill. Compare with the lifestyle group, the polypill cohort had 34% fewer adverse events. Results were similar for men and women. Blood pressure did not differ much, but “bad” (LDL) cholesterol levels were lower in the group taking medicines. “Now we know that a fixed-dose polypill can achieve clinical benefits in practice,” Malekzadeh said in a statement.

“But the polypill is not an alternative to a healthy lifestyle and should be combine with physical activity, a healthy diet, and smoking cessation.” Other researchers not involve in the study said the findings could be a game changer, especially in developing nations. “Given the polypill’s affordability, there is considerable potential to improve cardiovascular health; also to prevent the world’s leading cause of death,” note co-author Nizal Sarrafzadegan, a researcher at Isfahan University of Medical Sciences.

“Over three-quarters of the people of the 18 million people who die from cardiovascular diseases each year live in low and middle income countries.” Some experts including the authors themselves said further trials were need to see of the polypill would prove effective among other populations.
