Clinically, it manifests as fever, persistent cough, difficulty breathing, and pleuritic chest pain that worsens with deep breaths. [19] Hemothorax: A hemothorax occurs from accumulation of blood in the pleural cavity, commonly due to trauma, vascular injury, or coagulopathies, which can disrupt lung expansion and oxygenation.

Coronary arteries deliver oxygen-rich blood to the heart muscle. [5] Reduced blood flow to the heart associated with coronary ischemia can result in inadequate oxygen supply to the heart muscle. [6] When oxygen supply to the heart is unable to keep up with oxygen demand from the muscle, the result is the characteristic symptoms of coronary ...
Angina, also known as angina pectoris, is chest pain or pressure, usually caused by insufficient blood flow to the heart muscle (myocardium). [2] It is most commonly a symptom of coronary artery disease. [2] Angina is typically the result of partial obstruction or spasm of the arteries that supply blood to the heart muscle. [3]
People with coronary artery disease, or narrowing of the blood vessels supplying their heart, may develop symptoms such as: Chest pain that often gets worse with stress or physical activity ...
Symptoms include chest pain or angina, shortness of breath, and fatigue. [6]A completely blocked coronary artery will cause a heart attack. [6] Common heart attack symptoms include chest pain or angina, pain or discomfort that spreads to the shoulder, arm, back, neck jaw, teeth or the upper belly, cold sweats, fatigue, heartburn, nausea, shortness of breath, or lightheadedness.
The vessels that remove the deoxygenated blood from the heart muscle are the cardiac veins. These include the great cardiac vein, the middle cardiac vein, the small cardiac vein, the smallest cardiac veins, and the anterior cardiac veins. Cardiac veins carry blood with a poor level of oxygen, from the myocardium to the right atrium.
The heart does not contain veins, but rather coronary sinuses that serve the purpose of returning de-oxygenated blood from the heart muscle. [ citation needed ] A thrombus is a type of embolism , a more general term for any material that partially or fully blocks a blood vessel.
