An NSTEMI (Non-ST-Elevation Myocardial Infarction) occurs when the heart muscle doesn't receive enough blood supply to meet its needs. This lack of blood flow damages the heart muscle.
Understanding the Underlying Issues
The primary cause of NSTEMI is reduced blood supply to the heart. According to the provided reference, this can happen due to conditions that disrupt blood supply. Some of these conditions include:
- Severe high blood pressure (Malignant Hypertension or Hypertensive Emergency): Extremely high blood pressure can strain the heart and reduce effective blood flow.
- Low blood pressure (Hypotension): Insufficient blood pressure means the heart isn't getting enough blood.
These conditions can lead to an imbalance between the heart's oxygen demand and supply, ultimately causing an NSTEMI.
