Can High Calcium Cause Heart Attack?

High calcium levels, a condition known as hypercalcemia, can potentially contribute to an increased risk of heart-related issues, including heart attacks. Here’s how elevated calcium levels can impact cardiovascular health:

  1. Calcification of Arteries: High calcium levels can lead to the deposition of calcium in the arteries, a condition known as vascular calcification. This can cause the arteries to become stiff and narrow, reducing blood flow and increasing the risk of heart attack and other cardiovascular events.
  2. Arrhythmias: Elevated calcium levels can affect the electrical activity of the heart, leading to irregular heartbeats (arrhythmias). Severe arrhythmias can increase the risk of heart attack or other serious heart conditions.
  3. High Blood Pressure: Hypercalcemia can contribute to high blood pressure (hypertension), which is a significant risk factor for heart attacks and other cardiovascular diseases.
  4. Underlying Conditions: Conditions that cause hypercalcemia, such as hyperparathyroidism, certain cancers, or excessive vitamin D intake, can also indirectly increase the risk of heart disease.

It’s important to diagnose and manage hypercalcemia effectively. If you have high calcium levels, a healthcare provider will work to determine the underlying cause and appropriate treatment. Treatment may involve addressing the root cause (e.g., treating hyperparathyroidism), adjusting medications or supplements, and monitoring and managing cardiovascular risk factors. Regular check-ups and blood tests can help ensure that calcium levels remain within a healthy range and reduce the risk of heart-related complications.
