What are the factors influencing infarction?
The factors that influence infarction depend on the location and type of infarction. For example, a myocardial infarction (heart attack) is usually caused by a buildup of fat, cholesterol, and other substances in the heart's (coronary) arteries. This buildup forms plaques that can rupture and form aRead more
The factors that influence infarction depend on the location and type of infarction. For example, a myocardial infarction (heart attack) is usually caused by a buildup of fat, cholesterol, and other substances in the heart’s (coronary) arteries. This buildup forms plaques that can rupture and form a clot that blocks blood flow to the heart. Many risk factors for myocardial infarction are potentially modifiable, with the most important being tobacco smoking (including secondhand smoke), obesity, lack of physical activity, and alcohol use.

Infarction is tissue death due to a lack of oxygen caused by an obstruction of the tissue's blood supply. The clinical effects of infarction depend on the location and severity of the infarction.

Infarction is tissue death due to a lack of oxygen caused by an obstruction of the tissue’s blood supply. The clinical effects of infarction depend on the location and severity of the infarction. For example, a myocardial infarction (heart attack) occurs when blood flow to the heart is blocked, causing tissue in the heart muscle to die. Symptoms may include chest pain, sweating, nausea or vomiting, and fainting. A pulmonary infarction occurs when blood flow to the lungs is blocked, causing tissue in the lungs to die. Symptoms may include coughing or spitting up blood and shortness of breath.

The effects of acute haemorrhage depend on the amount and rapidity of blood loss, and the efficiency of the compensatory power of the subject. If severe haemorrhage is left untreated, you may experience chest pain, confusion, faster breathing or heart rate, organ failure, seizures, shock, coma, or dRead more

Haemorrhage is bleeding from a damaged blood vessel. Many things can cause haemorrhage inside and outside the body. Some common causes of haemorrhage include alcohol, drug, or tobacco use that is heavy or long-term, blood clotting disorders, cancer, complications from medical procedures such as surgery or childbirth, damage to an internal organ, hemophilia, leukemia, liver disease, menorrhagia (heavy or prolonged menstrual bleeding), thrombocytopenia (low blood platelet count), von Willebrand disease, vitamin K deficiency, and brain trauma.

Complications of oedema may include difficulty in walking, stiffness, stretched skin which can become itchy and uncomfortable, increased risk of infection in the swollen area, decreased elasticity of arteries, veins, joints, and muscles, and increased risk of skin ulcers.

Oedema is swelling caused by too much fluid trapped in the body's tissues. There are six factors that can contribute to the formation of oedema: 1. Increased hydrostatic pressure 2.

See less1. Increased hydrostatic pressure
2. Reduced colloidal or oncotic pressure within blood vessels
3. Increased tissue colloidal or oncotic pressure
4. Increased blood vessel wall permeability (such as inflammation)
5. Obstruction of fluid clearance in the lymphatic system
6. Changes in the water-retaining properties of the tissues themselves.
What are the fate of embolism?
The fate of an embolism depends on the type of embolism involved, its size, location, and the underlying health of the individual. For example, a pulmonary embolism is a blood clot that blocks and stops blood flow to an artery in the lung. In most cases, the blood clot starts in a deep vein in the lRead more
The fate of an embolism depends on the type of embolism involved, its size, location, and the underlying health of the individual. For example, a pulmonary embolism is a blood clot that blocks and stops blood flow to an artery in the lung. In most cases, the blood clot starts in a deep vein in the leg and travels to the lung. Because one or more clots block blood flow to the lungs, pulmonary embolism can be life-threatening. However, prompt treatment greatly reduces the risk of death.
The impact of a pulmonary embolism on the heart’s right ventricle function is the most common cause of pulmonary embolism death. For people with pulmonary embolism but no associated decrease in right ventricle function, estimates place mortality (death) at around 2%.

The clinical effects of an embolism depend on the type of embolism involved. For example, a pulmonary embolism is a blood clot that blocks and stops blood flow to an artery in the lung. In most cases, the blood clot starts in a deep vein in the leg and travels to the lung. Pulmonary embolism symptoms can vary greatly, depending on how much of your lung is involved, the size of the clots, and whether you have underlying lung or heart disease. Common symptoms include shortness of breath, chest pain, fainting, rapid or irregular heartbeat, lightheadedness or dizziness, excessive sweating, fever, leg pain or swelling, or both, usually in the back of the lower leg.
An air or gas embolism is a bubble that becomes trapped in a blood vessel and blocks it. This can lead to many different symptoms depending on where the blockage occurs. Symptoms of a severe air embolism might include difficulty breathing or respiratory failure and chest pain or heart failure.

An embolism is the obstruction of the flow of blood by an embolus, a particle or aggregate of substance that is abnormally present in the bloodstream.

An embolism is the obstruction of the flow of blood by an embolus, a particle or aggregate of substance that is abnormally present in the bloodstream. When a thrombus, a blood clot, becomes dislodged and a piece breaks off, it is called an embolus. The embolus can obstruct the pulmonary circulation, and the body sends a signal to release neurohormonal substances and inflammatory mediators, which cause vasoconstriction.
Pulmonary embolism occurs when clots break off and embolize into the pulmonary circulation. Pulmonary emboli are typically multiple, with the lower lobes being involved more frequently than the upper, and bilateral lung involvement being more common. Once deep venous thrombosis develops, clots may dislodge and travel through the venous system and the right side of the heart to lodge in the pulmonary arteries, where they partially or completely occlude one or more vessels.
