A concussion is typically recognized as a traumatic brain injury, but its impact can extend well beyond the skull. At Cardiac Solutions in Sun City, Glendale, and Peoria, AZ, our team frequently assesses patients who present with a variety of complex symptoms following head trauma. Alongside more familiar issues like headaches and cognitive disturbances, we sometimes encounter chest discomfort, palpitations, and other irregular heart rhythms in these individuals. Although such cardiovascular manifestations are relatively rare, emerging studies indicate that concussive forces may, in certain cases, disrupt autonomic regulation or provoke inflammatory responses that influence heart function.

Can a Concussion Cause a Heart Attack? Understanding the Risks

Blunt trauma to the head sets off a complex cascade of physiological responses that can ripple through numerous organ systems. In certain cases, these effects extend to the cardiovascular system, producing symptoms that may be unexpected, and in some instances, quite serious. Naturally, this overlap prompts the question: is it possible for a concussion to precipitate a heart attack? While the overall likelihood remains low, the relationship between brain injury and cardiac events is nuanced and merits consideration.

What Is a Concussion?

A concussion is a type of mild traumatic brain injury that results from a blow to the head or a violent jolt to the body. It temporarily alters brain function, leading to symptoms such as headache, dizziness, nausea, confusion, or difficulty concentrating. While most concussions resolve without long-term effects, some can cause lingering symptoms or affect other bodily systems. In some cases, individuals report cardiovascular symptoms such as palpitations or chest pain after concussion. These symptoms should not be ignored, especially if they worsen over time or are accompanied by other warning signs.

Understanding the Connection Between the Brain and the Heart

The brain and heart are closely linked through the autonomic nervous system, which controls involuntary functions such as heart rate and blood pressure. After a concussion, disruptions in brain signaling may affect how the heart responds to stress. This brain-heart connection plays a key role in what’s sometimes called cardiac concussion—a condition in which cardiac symptoms arise following head trauma. Though rare, these cases highlight the importance of monitoring both neurological and cardiovascular health after injury. Here’s how concussion may affect cardiac function:

  • Disruption of autonomic regulation may cause irregular heartbeat.
  • Stress-induced hormone release can elevate heart rate and blood pressure.
  • In extreme cases, a sudden neurological event may trigger cardiac arrest.

Can a Concussion Actually Cause a Heart Attack?

Although rare, there are documented cases where a head injury was followed by cardiac symptoms severe enough to raise concern for a heart attack. The combination of stress, inflammation, and autonomic dysfunction can place strain on the cardiovascular system, particularly in individuals with existing heart disease. While it’s not common for a concussion to directly trigger a heart attack, the physiological stress it places on the body may act as a catalyst in vulnerable individuals. When considering whether a concussion and heart attack could be linked, the following factors matter:

  • The patient’s pre-existing cardiovascular health
  • The severity of the concussion and the body’s stress response
  • The presence of symptoms such as chest pain, shortness of breath, or arrhythmia

Warning Signs: When to Seek Cardiac Help After a Concussion

After a concussion, most people focus on rest and neurologic recovery. However, some symptoms may indicate that the heart is also being affected. Recognizing these signs early can make a significant difference in outcomes. In cases of cardiac concussion, causes may include autonomic dysfunction or stress-induced heart strain, both of which require medical attention. Seek cardiac evaluation if you experience:

  • Chest pain or pressure not explained by musculoskeletal injury
  • Irregular heartbeat or noticeable palpitations
  • Shortness of breath during rest or mild activity
  • Dizziness or fainting that persists beyond the initial injury
  • Fatigue that feels disproportionate or unusual

Preventive Measures and What to Do Post-Concussion

Taking care of the heart following a concussion involves more than just rest. Monitoring symptoms, maintaining hydration, and managing stress all support the recovery process. This is especially important for individuals with a history of heart conditions or prior head injuries. By being proactive, you can lower the chances of complications and ensure a safer recovery. To support your recovery and reduce cardiac risk:

  • Follow all concussion protocols recommended by your healthcare provider.
  • Avoid intense physical activity until cleared by a physician.
  • Keep track of any cardiovascular symptoms that arise, even if they seem minor.
  • Ensure follow-up care includes evaluation of both neurological and cardiovascular health.
