Can You Get a Heart Attack from Pre Workout?

Learn whether you can get a heart attack from pre workout and the precautions you should take before using pre workout supplements.


The use of pre-workout supplements is increasingly popular among athletes, bodybuilders and fitness enthusiasts looking to maximize performance and results. There have been some reports of adverse effects in some users, most notably heart attacks. But is it possible to get a heart attack from taking pre-workout supplements? This article seeks to assess the possible risks associated with the use of these products and outline the prevention strategies that should be considered before taking them.

In order to get a complete picture of the potential dangers posed by pre-workout supplements, it is important to understand exactly what they contain. These products generally contain stimulatory compounds like caffeine, guarana, synephrine HCl, yohimbe bark extract and tyrosine. Other ingredients commonly found in pre-workouts include creatine monohydrate, beta alanine, branched chain amino acids (BCAAs), citrulline malate and arginine alpha ketoglutarate (AAKG). The intensity of the effects of these ingredients varies from person to person depending on their tolerance level.

Causes of Heart Attacks

Heart attacks can be caused by a variety of factors, and pre workout supplements may be one of them. Pre workout supplements can contain stimulants, such as caffeine and other ingredients, that can increase your heart rate and cause your body to put more strain on your heart. In this section, we’ll look into the causes of heart attacks and if pre workout supplements can be a factor.

High Blood Pressure

High blood pressure, or hypertension, is a major risk factor for cardiovascular disease. When you have high blood pressure, the force of the blood pushing against your artery walls is too strong. This can damage your arteries, making it easier for them to become blocked and cause a heart attack or other cardiovascular events. For this reason, controlling your high blood pressure is an important step in helping prevent heart attacks.

Uncontrolled hypertension can lead to coronary artery disease (CAD). CAD occurs when cholesterol deposits called plaques form on the walls of the coronary arteries that supply oxygen-rich blood to your heart. If one of these plaques breaks open, a clot may form at the site which can block off flow of blood through your coronary artery and cause a heart attack.

Other factors related to hypertension that raise your risk for a heart attack include dehydration and extreme dilation of the arteries due to large amounts of stimulants released by pre-workout supplements with excessive doses of caffeine or other stimulants like taurine and guarana. A combination of long periods without adequate fluids plus unopposed stress hormones stimulated by high levels of stimulants can put undue strain on an already fragile cardiovascular system leading to increased risk for death due to cardiac arrest or stroke.

High Cholesterol

High cholesterol levels can cause plaque to build up in your arteries and make them narrow, which is known as atherosclerosis. When there’s a blockage in the arteries, this restricts or stops the blood flow to your heart and can lead to a heart attack. High cholesterol is usually caused by eating unhealthy food and not getting enough physical activity. To reduce your risk of high cholesterol, minimize the intake of foods such as processed meat, high fat dairy products, sugary beverages or desserts, and fried foods. You should also aim to get at least 30 minutes of aerobic exercise every day.


People with diabetes have an increased risk of having a heart attack due to their high blood sugar levels. People with type 1 and type 2 diabetes are three times more likely to die from a heart attack than those without diabetes. This is because high blood sugar levels can damage the lining of the arteries, which can lead to blockages in the arteries that cause a heart attack. High levels of cholesterol and triglycerides in the blood can also increase a person’s risk of having a heart attack.

Having high blood pressure, or hypertension, increases the risk for both men and women who have diabetes. High blood pressure makes it difficult for your heart to pump enough oxygen and nutrients through your body, which can lead to narrowing and hardening of the artery walls. This can eventually lead to a heart attack or stroke if not treated properly. Also, people who are overweight or obese are at higher risk for developing type 2 diabetes as well as other cardiovascular diseases that increase risk for having a heart attack.


Smoking is one of the major causes of coronary heart disease which can result in a heart attack. The chemicals found in cigarette smoke are particularly damaging to the cardiovascular system and can harden and narrow arteries over time, leading to a blockage that disrupts normal blood flow. When these blockages become so severe that blood cannot properly travel between the heart and other parts of the body, it can result in a heart attack. The damage caused by smoking affects not only current smokers, but also those who were previously exposed to secondhand smoke. Quitting smoking or reducing your exposure to smoking is essential for protecting your heart from a possible attack.


Stress is one of the major causes of heart attacks, both in terms of physical and mental stress. Physical stress can be caused by strenuous activities like vigorous exercise, heavy lifting, or even extreme temperatures. Mental stress can come from a medical condition like depression and anxiety, or from an event that’s especially taxing-like an argument with someone you love, or even a job loss. The stress that accumulates over these experiences can put your body into “fight-or-flight” mode, and your heart may start to race and release adrenaline as a result. This in turn can trigger a heart attack in some cases, as the affected areas of the heart muscle become overworked. Additionally, prolonged periods of stress have been linked to inflammation which can weaken and damage blood vessels leading to a heart attack as well. It is important to manage your stress levels through relaxation techniques such as yoga or meditation, and to take breaks from strenuous activity if needed.

Pre Workout and Heart Attacks

Pre-workout supplements are becoming increasingly popular for gym-goers and athletes as a means to increase energy and endurance. While these supplements may provide a boost of energy for a workout, there is some concern that using pre-workout may be linked to cardiac events. In this article, we will look at the research surrounding pre-workout and heart attacks, and help you decide if they are safe to use.

Caffeine Content

Caffeine is a stimulant found in certain foods and beverages, and is the active ingredient in pre-workout supplements. While some studies have shown that moderate amounts of caffeine can improve performance during exercise, higher doses can cause an unsafe increase in heart rate and blood pressure. High levels of caffeine can also increase the risk of dehydration, while reducing the body’s ability to absorb water during a work out.

The amount of caffeine in pre-workout supplements varies by manufacturer, but they typically contain between 150-300 milligrams (mg) per serving. That’s nearly twice as much caffeine as what you would find in 8 oz of brewed coffee! The US Food & Drug Administration (FDA) cautions that no more than 400 mg per day should be consumed from all sources combined. If you take certain medications or have certain health conditions, your safe dose may be even lower than this recommendation.

If you are considering taking a pre-workout supplement and are especially sensitive to caffeine or if you are using other sources of caffeine throughout the day, it is important to closely read product labels or consult with your healthcare provider before use. This will help ensure that you stay within the recommended guidelines for safe usage and understand how different concentrations might affect your individual needs.

Stimulant Content

Pre-workout supplements generally contain several active ingredients, such as stimulants and other performance enhancers, that are intended to improve physical and mental performance during exercise. While these ingredients can lead to improvements in performance, there is evidence to suggest that too much of a stimulant content can cause adverse effects on the cardiovascular system.

The primary active ingredient in many pre-workout formulas is caffeine. In relatively small doses, caffeine can help improve focus, alertness and endurance during exercise. However, consuming large amounts of caffeine can lead to anxiety, nausea and an increased risk of cardiac arrhythmias (irregular heartbeat). Other stimulants like guarana or bitter orange are also commonly used in pre-workout supplements that have similar effects as caffeine but may not carry the same immediate risks associated with it.

In addition to stimulants, many pre-workouts also contain other performance boosters such as amino acids or branched-chain amino acids (BCAAs) for energy metabolism support and nitric oxide boosters for increased blood flow during exercise. More research needs to be done into whether these compounds have any negative impacts on heart health when taken regularly prior to workouts.

While no studies have shown a direct causal link between pre-workout use and heart attack risk due to their stimulant content, it is important that athletes be aware of potential dangers associated with taking too much of a specific supplement on a regular basis. Additionally, athletes should consult with their physician before beginning any new supplement regimen or making adjustments in terms of dosage or frequency.

Other Ingredients

Pre-workout supplements are becoming increasingly popular for those looking to boost their performance during exercise. While many of these supplements contain caffeine, other components might have less well-known effects on the body. In addition to caffeine, pre-workout supplements often include ingredients such as taurine, guarana, creatine, lactic acid and beta alanine. Depending upon the brand and type of supplement chosen, these ingredients can vary in individual quantity and combination.

Taurine is an amino acid that helps regulate blood flow throughout the body during exercise by decreasing lactic acid production and providing the muscles with nourishment. In addition to helping with muscle contraction, it also helps protect against dehydration by maintaining water balance in muscle cells. Guarana is a type of fruit extract that contains caffeine plus guaranine, an organic compound that works like caffeine but closer to a slow release form compared to regular coffee beans or other forms of caffeine. Guarana can work together with taurine to provide further energy for enhanced workout performance.

Creatine is an amino acid produced naturally in the body which provides fuel for extra energy during intense physical activity or high intensity workouts. When taken as a pre-workout supplement, it increases muscle mass and strength while also improving endurance levels when exercised over long periods of time at low intensity levels. Lactic acid is produced naturally by exercising muscles; however when taken outside of natural production it assists in reducing fatigue and boosting performance during exertion cycles by increasing aerobic capacity and lactate threshold pace/speed goals set ahead of physical exercises duration/effort levels. Beta alanine is used as a pre-workout ingredient because it increases muscular buffering capabilities while decreasing fatigue altogether with exercise duration times being met without feeling exhausted prematurely before predetermined goals are achieved during any given workout session which allows individuals looking to increase fitness levels over longer periods of time reach goals desired more efficiently than would be possible without supplementation being included within training sessions agenda(s).

Risk Factors

Pre workout supplements are designed to give you a burst of energy and an extra boost to help you push through your workouts. However, these supplements can also have some potentially dangerous side effects, including a possible increased risk of heart attack or stroke. So, what are the risk factors associated with pre workout supplements? Let’s take a look at the evidence.


Age is an important risk factor for heart attack, particularly because the risk of heart attack increases with age. People aged 65 and older are more likely to suffer a heart attack due to their bodies’ reduced ability to respond to physical strain. As we age, the cells in our hearts become less efficient at supplying oxygen-rich blood and dealing with waste, which can cause the arteries leading to our hearts to constrict or become blocked, leading to a heart attack. It’s also important that people of all ages be mindful of their blood pressure and cholesterol levels as they can increase one’s risk for a heart attack. Other factors such as lifestyle habits like smoking, drinking alcohol excessively, and poor diet can also contribute to increased risk for having a heart attack.

Family History

Family history is an important factor when it comes to cardiovascular disease and the risk of a heart attack. If you have a family history of cardiovascular disease, such as high blood pressure, diabetes, or coronary artery disease, there is an increased risk that you may also experience a heart attack due to pre-workout use. It should be noted that physical activity can be beneficial even if there is a family history of cardiovascular disease. However, those with this type of family history should always check with their doctor beforehand and get any necessary preventative care or testing done prior to starting any exercise program.


Gender is a key factor when looking at heart attack risk. Men are more likely to suffer from a heart attack compared to women, especially before the age of 55. Research has linked this difference to particular hormones, particularly testosterone and estrogen, which can alter both visible and invisible physiological characteristics that lead to increased risk in men.

In terms of age, men have an increased risk for heart attack after the age of 45 and women after the age of 55, although this can vary greatly for both genders depending on various lifestyle and health factors. Some studies have found that pre-menopausal women may actually have a slightly lower risk than men around the same age due to naturally occurring protective estrogen levels.

It is also important to note that certain medical conditions can increase risks for either genders before pre-determined ages including high blood pressure, diabetes and high cholesterol levels along with many genetic markers. If any of these conditions are present in an individual’s medical history it is important to discuss potential risks with a doctor prior to introducing pre-workout supplements in their regimen.


Weight is a major risk factor for developing coronary heart disease or having a heart attack. Being overweight or obese increases your chances of having a heart attack, as well as other cardiovascular diseases. If you are carrying extra weight and engage in pre-workout activities like lifting weights, running, or cycling, it’s important to take extra precautions. Pre-workout exercises can put extra stress on the heart that could lead to an acute cardiac event such as a heart attack if you are not careful.

Additionally, people who carry excess weight typically have issues with body image and therefore may be more likely to push themselves harder than their bodies can handle during pre-workouts. This leads to overexertion which could weaken the cardiovascular system and cause serious damage, including triggering a heart attack. Focus on being conscious of your limits so that you can safely engage in physical activity while managing your cardiovascular risk factors. Consulting with your healthcare provider before beginning any exercise regimen can also help in ensuring that you’re healthy enough for physical activity to avoid any risks associated with overexertion or potential cardiac events such as a heart attack.

Activity Level

The activity level of a person is an important factor in potential heart attack risks associated with taking pre-workout supplements. Generally, healthier individuals possess a higher activity level that has been adapted to over time and matches the amount of physical work the person does on a regular basis. For these individuals, utilizing pre-workout supplements in moderation to supplement their already active lifestyle may be beneficial; however, people who are sedentary or who engage in sporadic physical activities may risk straining their bodies more than they are ready for. Therefore, it is essential that such people consider their activity level before using any form of pre-workout supplement. People starting out on a fitness program should ideally begin with low intensity workouts and gradually increase both the frequency and intensity as they become fitter. This gradual increase allows the body’s cardiovascular system to adapt to more intense strain gradually and thus reduces potential heart risk factors associated with taking pre-workout supplements when in lower physical shape.


In conclusion, it is safe to say that there may be a small risk of heart attack associated with pre-workout supplements and servings of energy drinks when taken in large doses on a regular basis. A normal amount taken occasionally will likely not be dangerous, but it is important to understand that the ingredients in these types of supplements and drinks can cause heart problems. Taking these products in large amounts or frequently could increase the likelihood of side effects like an elevated heartbeat and chest pains. As such, it is suggested that anyone considering using them consult with their healthcare provider before doing so to make sure they are not taking too much. Also, keep in mind that even if no ill side effects occur, they may still leave you feeling jittery and exhausted post-workout due to their high levels of stimulants like caffeine.
