High coffee consumption is associated with an increased risk of abdominal arterial calcification (AAC) in people with hypertension, diabetes and cardiovascular disease, a new study has found.

While moderate coffee consumption is believed to reverse life-threatening diseases like metabolic syndrome, Parkinson's Disease (PD), type 2 diabetes and some cancers, excessive intake of caffeine can increase the risk of cardiovascular diseases in people with hypertension, researchers say.

The study, published in the journal Nutrition, Metabolism, and Cardiovascular Diseases, suggested that it's imperative to adopt caution in coffee intake to reduce the risk of AAC.

The study highlights that caffeine's blood pressure-raising nature may contribute to an increased risk of cardiovascular disease in people with severe hypertension. Furthermore, researchers found a connection between lower coffee consumption and calcification of the coronary arteries. The study used abdominal arterial calcification as an early marker of atherosclerosis, which develops before the onset of symptoms.

The team looked at information from a large survey that included more than 2,500 people. They used special scans to check for a problem called abdominal aortic calcification (AAC), which can show early signs of heart disease. They found that people who drank a lot of coffee and had conditions like high blood pressure, diabetes or heart problems had a higher risk of AAC. This means they should be careful about how much coffee they drink to keep their hearts healthy, according to News-Medical.

The study further emphasized that coffee can temporarily raise blood pressure, disrupt blood vessel function, impair glucose absorption, increase stress response and disrupt sleep patterns. Excessive coffee consumption may have harmful effects on individuals with abdominal aortic calcification (AAC) risk factors. Some studies show increased risks of cardiovascular death and sudden cardiac death in people with hypertension or those with existing cardiovascular disease (CVD) who consume excessive coffee, but more research is needed to clarify these findings.
