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 ...
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.

Bilharzial cor pulmonale is the condition of right sided heart failure secondary to fibrosis and sclerosis of the pulmonary artery branches. It results from shifting of the Schistosoma haematobium ova from the pelvic and vesical plexus to the pulmonary artery branches where they settle and produce granuloma and fibrosis.
It is also important to control heart disease risk factors including diabetes, high cholesterol, and high blood pressure. Exercise, pregnancy, and prior health conditions like ASD II can also promote cardiac remodeling, so routine primary care visits are important to distinguish between physiological and pathological atrial enlargement.
A study finds that people who engage in just 30 minutes of exercise per week see modest improvements in body weight and body fat but for clinically significant improvements they need a higher average.
Cor pulmonale PAH is considered a universally fatal illness, although survival time may vary between individuals. The prognosis of pulmonary arterial hypertension (WHO Group I) has an untreated median survival of 2–3 years from time of diagnosis, with the cause of death usually being right ventricular failure ( cor pulmonale ).

The Graham Steell murmur is often heard in patients with chronic cor pulmonale (pulmonary heart disease) as a result of chronic obstructive pulmonary disease. [ citation needed ] In cases of mitral obstruction the murmur is occasionally heard over the pulmonary area and below this region, for the distance of an inch or two along the left border ...
In light of Pope Francis’ latest diagnosis, Dr. Leana Wen explains why older adults are especially at risk for serious disease due to respiratory infections.
