Drinking Coffee May Reduce Heart Disease Risk

Three separate studies presented during the recently held American College of Cardiology ACC 2022 Scientific Session report that regular coffee drinking may be beneficial in reducing the risk of cardiovascular disease (CVD).

The research studies were analyses of 10-year data from the UK Biobank. The UK biobank is a database of around 500,000 volunteers in the United Kingdom created to investigate the relationship of multiple factors like genetics, nutrition, lifestyle, etc. to the development of disease.

Chieng reports that people who drink two to three cups of coffee every day showed 8% to 15% reduced risk of death and CVD diseases like coronary heart disease, cardiac failure and stroke.

In a separate report from Kistler, regular coffee consumption does not increase the risk of arrhythmia* in those who have pre-existing CVD disease, and patients with arrhythmia drinking 2-3 cups showed improved mortality rates.

The third report from Chieng suggests that the clinical benefits of coffee are similar regardless of whether it was instant or ground coffee.  

There have been numerous studies in the past outlining the health effects of coffee. However, there have been persistent beliefs that coffee may trigger irregular heartbeats or worsen heart disease. But as the studies show, coffee can be considered part of a healthy heart diet. Coffee contains more than 100 biologically active compounds, some of which have antioxidant and anti-inflammatory properties which reduce stress and improve metabolism.  

However, just with anything else, moderation is key. The takeaway message from these recent studies is that moderate amount of coffee drinking will not cause harm and can potentially bring about healthy benefits.

Cardiac ablation is a minimally invasive procedure used to treat cardiac arrhythmias. An ablation catheter is inserted through a blood vessel to cause a scar around a target area to disrupt the flow of the irregular heart rhythm. The Technowood SSS guidewire H503 series was designed to provide additional support and stability for placing devices such as sheaths and catheters during procedures like ablation. *Stainless spring guidewire is also available.
