The pathophysiology of pulmonary heart disease (cor pulmonale) has always indicated that an increase in right ventricular afterload causes RV failure (pulmonary vasoconstriction, anatomic disruption/pulmonary vascular bed and increased blood viscosity are usually involved [1]), however most of the time, the right ventricle adjusts to an ...
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...
Diabetic coma is a medical emergency in which a person with diabetes mellitus is comatose (unconscious) because of one of the acute complications of diabetes: [24] [25] Severe diabetic hypoglycemia Diabetic ketoacidosis advanced enough to result in unconsciousness from a combination of severe hyperglycemia , dehydration and shock , and exhaustion
When this leads to right sided heart failure, it is known as cor pulmonale. [4] Symptoms of this disorder occur because the heart has difficulty pumping blood from the body through the lungs. Fluid may, therefore, accumulate in the skin of the legs in the form of edema (swelling), and in the abdominal cavity in the form of ascites ; decreased ...
An ECG may show signs of right heart strain or acute cor pulmonale in cases of large PEs – the classic signs are a large S wave in lead I, a large Q wave in lead III, and an inverted T wave in lead III (S1Q3T3), which occurs in 12–50% of people with the diagnosis, yet also occurs in 12% without the diagnosis.

Diabetic cardiomyopathy is a disorder of the heart muscle in people with diabetes.It can lead to inability of the heart to circulate blood through the body effectively, a state known as heart failure(HF), [2] with accumulation of fluid in the lungs (pulmonary edema) or legs (peripheral edema).
Diabetes [22] Cardiomegaly can also occur non-pathologically as part of athletic heart syndrome (AHS) in individuals who frequently engage in high-intensity physical exercise, for instance endurance athletes and other individuals who exercise for more than 1 hour daily. [23]
Chronic alveolar hypoxia is the main factor leading to development of cor pulmonale — right ventricular hypertrophy with or without overt right ventricular failure — in patients with COPD. Pulmonary hypertension adversely affects survival in COPD, proportional to resting mean pulmonary artery pressure elevation.
