Caffeine and Heart Attacks

Energy drinks often contain hundreds of milligrams of caffeine, sugar, and supplements. Caffeine is a mild stimulant, but it is toxic in high doses. Overdoses can increase heartbeat and cause palpitations (cardiac arrhythmia) or cardiac arrest. Most energy drinks do not list the amount of caffeine on the label or warn about heart attacks.

Do Energy Drinks Cause Heart Attacks?

In November 2012, the FDA announced that it was investigating reports of five deaths and one non-fatal heart attack linked to energy drinks.

The announcement was likely prompted by a wrongful death lawsuit filed by the family of a 14 year-old girl who died of cardiac arrhythmia due to caffeine toxicity after drinking two cans of Monster Energy.

The FDA received reports of the following cardiovascular events linked to Red Bull and 5 Hour Energy, Monster, and Rock Star:

  • Heart attack
  • Myocardial infarction
  • Blood clot in the heart
  • Increased heart rate
  • Tachycardia
  • Chest pain
  • High blood pressure
  • Cardiac disorder
  • Abnormal heart rhythm
  • Palpitations

Just One Energy Drink Could Increase Risk of Heart Attack

In November 2015, researchers at the Mayo Clinic published a study in JAMA Internal Medicine linking energy drinks with increases in blood pressure, heart rate, and stress hormones — all risk-factors for heart attacks.

Researchers concluded that drinking just one 16-oz energy drink can increase the odds of heart disease in healthy young adults. Conclusions were based on data from 25 healthy young adults (average age 29) who drank an energy drink or a placebo.

People who consumed energy drinks had higher blood pressure and 74% higher levels of norepinephrine. This stress hormone increases heart-rate and constricts blood vessels, which can predispose patients to heart attacks. According to researchers:

“We now show that the increases in blood pressure are accompanied by increases in norepinephrine, a stress hormone chemical, and this could predispose an increased risk of cardiac events – even in healthy people.”

What is a Heart Attack?

A heart attack occurs when the flow of oxygen-rich blood to the heart muscle is cut off. If the blockage is not removed, the heart begins to die and it stops pumping blood.

Warning Signs of a Heart Attack

The most common sign of a heart attack is chest pain. Most heart attacks cause discomfort, pain, squeezing, burning, or pressure in the center or left side of the chest. The feeling may come and go or last for several minutes. It may spread to the arms, back, shoulders, neck, jaw, or upper part of the stomach.

Heart Attack Symptoms

  • Chest pain
  • Upper body pain or discomfort
  • Shortness of breath
  • Breaking out in a cold sweat
  • Tiredness
  • Nausea and vomiting
  • Light-headedness or dizziness
  • Anxiety
  • And more


People who survive a heart attack may suffer complications, such as abnormal heart rhythm, heart failure, heart rupture, or valve problems. The severity of these complications depends on how much heart tissue was damaged. Scar tissue weakens the heart and decreases its ability to pump blood.


Heart attacks are medical emergencies that must be treated in a hospital. Every minute counts. Treatment typically involves intravenous (IV) thrombolytic (“clot-busting”) drugs, blood-thinners, pain relievers, and other medications. Patients may need surgery to open blocked arteries during severe heart attacks. In some cases, emergency bypass surgery is necessary to restore circulation.
