Their large bodies are streamlined (hydrodynamic), like a submarine, for movingthrough the water. Whales have flukes or a tail used for swimming. The flukes are moved in an up-and-down motion to accelerate. The dorsal fin acts like the keel of a boat; it keeps the whale from rolling side to side while swimming.

Sphinxa [80]

Acute inferior myocardial infarction. Documented mildly occlusive plaque with much clot in the right coronary artery

<h3>What is myocardial infarction?</h3>
  • A myocardial infarction (MI), also referred to as a heart attack, happens when blood flow to the heart's coronary artery is reduced or interrupted, harming the heart muscle.
  • The most typical symptom is discomfort or soreness in the chest, which may radiate to the shoulder, arm, back, neck, or jaw. It frequently lasts more than a few minutes and usually happens in the center or left side of the chest.
  • Sometimes the discomfort may feel like heartburn. Other signs and symptoms could include fatigue, shortness of breath, nausea, feeling dizzy, and cold sweats.
  • Atypical symptoms are present in about 30% of patients. Women more frequently experience arm, neck, or fatigue discomfort instead of chest pain.
