Study suggests the heart benefits from coffee — but the preparation method matters - Salon

New research in the European Journal of Preventive Cardiology analyzed a large database of coffee drinkers and found that people who drank around 2 to 3 cups per day had better cardiovascular health than controls.

"However, most follow-up studies did not have direct evidence that coffee can cause cardiovascular disease.".

Regardless of caffeine's effect on blood pressure, some health experts have warned against using it, especially in people with cardiovascular diseases.

Patients were screened for cardiovascular disease (including coronary heart disease, congestive cardiac failure and stroke), arrhythmias or irregular heartbeats, and death from any cause.

They researchers found that no matter what kind of coffee people drank, even decaf, it significantly reduced risk of cardiovascular disease, arrythmias and death compared to controls.

While around 28,000 participants (6 percent) died during long-term follow-up, including 4,400 (1 percent) from cardiovascular causes, that effect was greatly reduced when coffee was added to the mix.
