Study Notes

Cardiovascular Disorders and Thrombosis

Circulatory disturbances can lead to hypovolemic shock, cardiogenic shock, septic shock, and anaphylactic shock due to various pathogenic factors.
Shock occurs when blood flow or pressure is too low to supply the body adequately, potentially becoming life-threatening.
Arterial thrombosis is primarily caused by vessel wall injury from arteriosclerosis, leading to infarcts in various arteries, such as coronary, leg, and cerebral arteries.
Intracardiac thrombosis may dislodge into systemic circulation, causing infarction in major organs like the spleen, kidneys, brain, and lungs.
Thrombosis can occur within the atria, on damaged heart valves, and on the wall of the left ventricle, often due to increased coagulability from factors like polycythemia, contraceptive pills, and hereditary gene mutations.
Patients with cancer are predisposed to arterial and venous thromboses due to the rapid release of thromboplastic materials into circulation from tumors, causing hypercoagulability.
Disseminated Intravascular Coagulation (DIC) can occur in patients with cancer due to increased platelets and coagulation factors.
Arteriosclerosis is a chronic and progressive degenerative disease of large to mid-sized arteries, leading to the accumulation of inflammatory and immune cells, cholesterol, and lipids, resulting in atheroma formation.
Atherosclerosis is characterized by the narrowing of arteries due to lipid deposits from the bloodstream, leading to the formation of atheromatous plaques surrounded by fibrous tissue.
Atheromatous deposits in advanced atherosclerosis can lead to permanent narrowing of vessels and are associated with risk factors such as elevated blood lipids, high blood pressure, smoking, and diabetes.
Stable plaques and ulcerated plaques covered by thrombus material are examples of atheromatous deposits that contribute to the narrowing of arteries and potential complications.
Genetic factors play a significant role in atherosclerosis, with an impact of 40-60%, making it a non-modifiable risk factor.
