How does caffeine affect the heart?

Caffeine affects the heart in multiple ways. Firstly, it promotes the release of noradrenaline and norepinephrine. Among other things, these hormones increase heart rate and blood pressure. Additionally, caffeine can act on enzymes that stimulate heart contractions, causing the heart to contract with more force.

Caffeine is an incredibly popular stimulant. More than 85% of the United States population consumes at least one caffeinated beverage each day, and 96% of that consumption comes from coffee, tea, and soft drinks. If you enjoy caffeinated beverages but have noticed heart palpitations, you may wonder whether your daily cup of joe is to blame. Rely on board-certified cardiovascular physician Ayim Djamson, MD, and his team at Metropolitan Cardiovascular Consultants to help you keep your heart as healthy and as strong as possible. Heart palpitations, though brief and short-lived, shouldn’t be ignored, as they could signal an underlying issue with your heart. Visit us if you suspect that lifestyle habits such as drinking caffeine are causing your heart symptoms. Dr. Djamson performs a comprehensive evaluation to check your heart health. Here we discuss caffeine, how it can lead to heart palpitations, and what you can do about it.

What are heart palpitations?

Most of the time, you’re likely unaware of the beating or rhythm of your heart. A normal resting heart rate is 60 to 100 beats-per-minute, and the heart has a characteristic rhythm when it beats. Unless your heart is beating fast or hard, you likely won’t notice it beating. Heart palpitations are the feeling that your heart is beating irregularly. It may feel like it’s pounding, beating too fast, or fluttering. Common causes of heart palpitations include:

Stress

Exercise

Certain medications

Stimulants, including caffeine, are known to affect heart rate, but just how does caffeine affect the heart?

Caffeine and your heart

Caffeine is one of the most researched dietary components, and we know a lot about how it affects the body. However, research examining caffeine’s link to heart palpitations has been conflicting, with some studies showing a connection and others not. This is because in healthy people, caffeine does not appear to cause heart palpitations. However, some people may be more sensitive to the effects of caffeine and may experience heart symptoms such as palpitations. Caffeine affects the heart in multiple ways. Firstly, it promotes the release of noradrenaline and norepinephrine. Among other things, these hormones increase heart rate and blood pressure. Additionally, caffeine can act on enzymes that stimulate heart contractions, causing the heart to contract with more force.

Is caffeine causing my heart palpitations?

For years researchers believed caffeine’s stimulant effects on the heart were responsible for heart palpitations. Recent research suggests this isn’t necessarily the case. That doesn’t mean caffeine isn’t causing your heart symptoms, and it doesn’t vindicate caffeine completely. The body adapts to the effects of caffeine. Therefore, healthy people who regularly drink coffee are unlikely to experience symptoms such as heart palpitations. Caffeine can cause heart palpitations in people with a sensitivity to caffeine and those with an underlying heart condition. If you’re new to caffeine consumption or drink excess amounts, you’re more likely to experience heart symptoms. The only way to know for sure is to visit a heart specialist for a checkup.

Importance of a heart health check

If you’re having heart symptoms, it’s crucial to get a medical evaluation. Various heart conditions can cause heart palpitations, including:

Atrial fibrillation

Mitral valve prolapse

Heart failure

Congenital heart disease

Cardiomyopathy

Atrial flutter

Some of these conditions can be serious and require treatment.
