Cardiologist Jorge Tartaglione said on Argentine broadcaster LN+ that moderate coffee consumption was not linked to a higher likelihood of arrhythmia, while drinking more than four cups a day could raise the risk of heart problems.
Tartaglione said one to three cups did not increase the likelihood of an irregular heartbeat. He described consumption of two to four cups as associated with fewer heart diseases. He also stressed that cup size matters, so counting cups alone may not capture how much coffee someone drinks.
The cardiologist said blood pressure may rise slightly just after drinking coffee and then fall. He also referred to a link between regular consumption and type 2 diabetes, but the broadcast did not provide details of the study he cited. The remarks should not be treated as individual medical advice.
Tartaglione separately warned against energy drinks because of their high concentration of ingredients. He favored coffee brewed through a paper or cloth filter, saying it can retain compounds that may raise cholesterol. He also urged people to account for sugar and syrups, noting that sweet additions change the drink.
