Substance abuse poses significant risks to cardiovascular health, leading to potentially irreversible damage. Among the many health concerns linked to drug use, heart damage is one of the most critical. This article explores the signs of heart damage caused by drug use.

Various substances, including cocaine, methamphetamine, and even prescription medications when misused, can have significant cardiovascular repercussions as The American Heart Association (AHA) notes [1]: “…the side effects and risks for your heart associated with the use of these drugs include: 

• Changes in body temperature, heart rate, and blood pressure
• The possibility of added substances, such as talc, poisons, herbicides, or other particles, which may cause a toxic reaction
• High blood pressure, arrhythmias, cardiomyopathy, peripheral artery disease, increased blood clotting and arterial plaque formation
• Ischemia, heart attacks, other acute coronary events, and stroke
• Increased mortality in those with preexisting cardiovascular disease

Injecting illegal drugs also can lead to cardiovascular problems, such as collapsed veins and bacterial infections of the blood vessels and heart valves.

Understanding Heart Damage

Heart damage can manifest in various forms, significantly impacting health and quality of life. Some of the most prevalent types of heart damage include cardiomyopathy, arrhythmia, and coronary artery disease, each presenting unique challenges to cardiovascular health.

Types of Heart Damage

Cardiomyopathy

This condition involves the weakening of the heart muscle, making it harder for the heart to pump blood to the rest of the body. Cardiomyopathy can lead to heart failure if left untreated. Different types include dilated, hypertrophic, and restrictive cardiomyopathy, each with distinct characteristics and causes. 

Arrhythmia

Arrhythmias are irregular heartbeats. They can result from a heart beating too fast (tachycardia), too slow (bradycardia), or irregularly. Arrhythmias disrupt the normal flow of blood, potentially leading to more severe complications. Stimulants can cause the heart to beat faster and may lead to the development of more serious arrhythmias. Illegal drugs, such as amphetamines and cocaine, may greatly affect the heart. Some may cause sudden death due to ventricular fibrillation. [2]

Coronary Artery Disease (CAD)

CAD occurs when the major blood vessels that supply the heart with blood, oxygen, and nutrients (coronary arteries) become damaged or diseased. Cholesterol-containing deposits (plaques) and inflammation are usually to blame. CAD is the most common form of heart disease and a leading cause of death worldwide.[3]

How Drugs Can Cause Heart Damage:

Drugs, especially stimulants like cocaine and methamphetamine, can lead to heart issues through various mechanisms:

Cocaine

Cocaine is known as “the perfect heart attack drug” [1]. It can cause coronary arteries to spasm, leading to decreased blood flow to the heart muscle and potential heart attack, even in the absence of any underlying cardiovascular diseases. Cocaine use also increases the risk of developing arrhythmias and cardiomyopathies. 

The AHA reported that “research shows cocaine users may have:

• Angina and reduced blood flow to the heart.
• Higher blood pressure, stiffer arteries, and thicker heart muscle walls.
• Sharp rise in heart rate and an increased need for oxygen in heart muscle.
• Damage to cardiac tissue.
• Heart infections.

All of these issues can lead to a heart attack, heart failure, stroke, or aneurysm.”      

Methamphetamine

Similar to cocaine, methamphetamine can cause significant cardiovascular problems, including increased heart rate and blood pressure, leading to the risk of heart attacks, arrhythmias, and even heart failure. Methamphetamine use has also been linked to the development of cardiomyopathy. Research shows that the leading cause of death in methamphetamine users is cardiovascular disease [4]. 

Other Drugs

Besides stimulants, other substances, including some prescription medications, can have detrimental effects on heart health. The mechanisms can vary, ranging from causing direct damage to the heart muscle, and altering heart rhythm, to affecting blood pressure and heart rate.

The AHA notes “Using opioids through injection can lead to infective endocarditis, a serious infection of the heart lining, caused by needles that are shared or dirty. Opioids are also associated with cardiac arrest.’ [1]

Ecstasy, or MDMA affects blood pressure and heart rate.  Smoking marijuana can make the heart beat faster and can make blood pressure higher immediately after use. It could also lead to an increased risk of stroke, heart disease, and other vascular diseases.  [1]

Understanding the types of heart damage and how drug use can contribute to these conditions is crucial for prevention and treatment. Addressing substance abuse and seeking medical intervention early can significantly reduce the risk of heart damage and its life-threatening consequences.

Common Signs of Heart Damage from Drug Use

Heart damage from drug use is a serious health concern that can manifest through various physical symptoms and behavioral signs. Understanding these indicators is important for recognizing the need for medical intervention. Drug-induced heart damage can be subtle or severe, affecting individuals differently based on factors like the type of substance used, duration of use, and overall health. Here’s a closer look at common signs of heart damage from drug use.

Physical Symptoms

Chest Pain

One of the most alarming symptoms suggestive of heart damage is chest pain or discomfort, which may feel like pressure, fullness, or a squeezing sensation in the chest. This pain can be a sign of reduced blood flow to the heart muscle, often indicative of coronary artery disease or a potential heart attack.

Shortness of Breath

Difficulty breathing or shortness of breath, especially with exertion or while lying down, can signal heart failure or other heart-related conditions. This occurs when the heart struggles to pump blood efficiently, causing fluid to back up in the lungs.

Fatigue

Unusual tiredness or weakness may also indicate heart damage, as the heart’s compromised ability to circulate blood results in less oxygen reaching the muscles and organs, leading to fatigue.

Swelling

Fluid retention in the body’s tissues, known as edema, can cause swelling in the legs, ankles, feet, or abdomen. This symptom often suggests heart failure, where the heart’s pumping capacity is diminished.

Palpitations

Experiencing heart palpitations, characterized by irregular heartbeats or a racing heart, can be a sign of arrhythmias, which are common in individuals with drug-induced heart damage.

Behavioral Signs

Beyond physical symptoms, certain behavioral changes may hint at underlying heart issues due to drug use:

Increased Anxiety or Panic Attacks

While anxiety can have various causes, sudden onset panic attacks or increased anxiety levels without a clear reason can be related to heart problems, exacerbated by stimulant drugs like cocaine or methamphetamine.

Changes in Activity Level

A noticeable decrease in physical activity tolerance or reluctance to engage in previously manageable activities can indicate a decline in heart function.

Risk-Taking Behavior

Continuing to use drugs despite knowing the health risks, including potential heart damage, is a significant behavioral sign. This compulsive behavior often overlooks the severe consequences of substance abuse.

Withdrawal from Social Interactions

Individuals suffering from heart issues may withdraw from social activities, partly due to fatigue, depression, or the physical inability to participate in such events.

Recognizing these physical symptoms and behavioral signs is pivotal in seeking timely medical attention. Heart damage from drug use is a critical condition that requires a comprehensive approach to treatment, including addressing the substance abuse itself and its cardiovascular impacts. Early intervention can significantly improve outcomes, underscoring the importance of awareness and supportive care.

At-Risk Substances

The relationship between substance use and heart health is complex, with numerous drugs, both illicit and prescription, posing significant risks when misused. Understanding which substances carry a high risk of causing heart damage is important for prevention efforts and healthcare guidance. This overview will highlight specific drugs known for their cardiovascular risks and touch upon emerging research in the field of drug-induced heart damage.

Drugs Known to Affect the Heart

Cocaine

Cocaine is widely recognized for its immediate and long-term cardiovascular effects. It can cause acute spikes in blood pressure and heart rate, leading to arrhythmias, myocardial infarction (heart attack), and even sudden cardiac death. Cocaine’s ability to constrict blood vessels while increasing the heart’s oxygen demands sets the stage for numerous potential cardiac events.

Methamphetamine

Similar to cocaine, methamphetamine use is associated with increased heart rate and blood pressure, raising the risk of heart attacks, heart failure, and arrhythmias. Chronic use can lead to the development of cardiomyopathy, a disease of the heart muscle that affects its ability to pump blood effectively.

MDMA (Ecstasy/Molly)

MDMA is known for its stimulant and psychoactive effects, which can also strain the cardiovascular system. It can lead to acute dehydration, hyperthermia, and electrolyte imbalance, all of which can indirectly contribute to heart stress and complications.

Anabolic Steroids

Often used to enhance physical performance and muscle growth, anabolic steroids can have severe cardiovascular side effects, including increasing the risk of heart attacks and strokes. These substances can lead to changes in cholesterol levels, hypertension, and heart muscle damage.

Prescription Medications

Certain prescription medications, when misused, can also pose risks to heart health. Stimulants prescribed for ADHD, like amphetamine and dextroamphetamine, can increase blood pressure and heart rate. Some weight loss medications and antidepressants are also associated with increased heart risks when not used as directed.

Emerging Research on Drug-Induced Heart Damage

Recent studies have begun to shed light on the cardiovascular risks associated with newer or less commonly abused substances, including synthetic cannabinoids (“spice”) and synthetic cathinones (“bath salts”). These substances have been linked to unpredictable and potentially severe cardiovascular effects, including acute myocardial infarction and arrhythmias. Research is ongoing to understand the full scope of their impact on heart health.

Additionally, the burgeoning field of research into the long-term cardiovascular effects of cannabis use is gaining attention. While cannabis is often perceived as less harmful, some studies suggest potential links between chronic use and an increased risk of hypertension, heart disease, and stroke, though findings are still mixed and warrant further investigation.

Understanding the cardiovascular risks associated with drug use is an evolving field, with ongoing research crucial for identifying at-risk substances and developing effective prevention and treatment strategies. As new substances emerge and patterns of use change, staying informed about the latest findings is vital for public health and individual well-being.
