However, according to older research from 1997, it is not the amount of caffeine in coffee that may affect cholesterol levels but rather the oils that naturally occur in the coffee bean. Study results on the association between coffee drinking and higher levels of serum cholesterol are mixed, according to a 2001 research review.Ī more recent 2016 study suggests that coffee consumption is linked to higher cholesterol levels, although the effects vary depending on the type of coffee and the sex of the individual. The findings were presented at the American Heart Association's Epidemiology and Prevention conference.Share on Pinterest Westend61/Getty Images ' People with health concerns or those who are older might have more heart-related side effects from energy drinks.' 'Since energy drinks also contain caffeine, people who do not normally drink much caffeine might have an exaggerated increase in blood pressure. 'Patients with high blood pressures or long QT syndrome should use caution and judgment before consuming an energy drink. The researchers also found that the systolic blood pressure, the top number in a blood pressure reading, increased an average of 3.5 points in a pool of 132 participants.ĭoctors have warned the drinks may disturb the heart's natural rhythmĭr Shah added: 'The correlation between energy drinks and increased systolic blood pressure is convincing and concerning, and more studies are needed to assess the impact on the heart rhythm. The finding that energy drinks could prolong the QT, in light of the reports of sudden cardiac death, warrants further investigation.' 'QT prolongation is associated with life-threatening arrhythmias. Lead author Doctor Sachin Shah, assistant professor at University of the Pacific in the United States, said: 'Doctors are generally concerned if patients experience an additional 30 milliseconds in their QT interval from baseline. ![]() ![]() The QT interval describes a segment of the heart's rhythm on an electrocardiogram when prolonged, it can cause serious irregular heartbeats or sudden cardiac death. They found that the QT interval was 10 milliseconds longer for those who had consumed the energy drinks. In the first part of the pooled analysis, the researchers examined the QT interval - a segment of the heart's rhythm - of 93 people who had just consumed one to three cans of energy drinks. The pooled studies included healthy patients, aged 18 to 45.
