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 overload in chronic pressure.
The second is OHS primarily due to "sleep hypoventilation syndrome"; this requires a rise of CO 2 levels by 10 mmHg (1.3 kPa) after sleep compared to awake measurements and overnight drops in oxygen levels without simultaneous apnea or hypopnea. [4] [11] Overall, 90% of all people with OHS fall into the first category, and 10% in the second. [5]
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.
Cholecystectomy is the surgical removal of the gallbladder.Cholecystectomy is a common treatment of symptomatic gallstones and other gallbladder conditions. [1] In 2011, cholecystectomy was the eighth most common operating room procedure performed in hospitals in the United States. [2]
This can lead to strain on the right side of the heart, a condition known as cor pulmonale. Pulmonary edema, leakage of fluid from capillaries of the lung into the alveoli (or air spaces). It is usually due to congestive heart failure. Pulmonary hemorrhage, inflammation and damage to capillaries in the lung resulting in blood leaking into the ...
[27] Removal of the gallbladder with surgery, known as a cholecystectomy, is the definitive surgical treatment for biliary colic. [28] A 2013 Cochrane review found tentative evidence to suggest that early gallbladder removal may be better than delayed removal. [29] Early laparoscopic cholecystectomy happens within 72 hours of diagnosis. [13]

Gallbladder and biliary-related diseases occurred in about 104 million people (1.6% of people) in 2013 and resulted in 106,000 deaths. [8] [9] Gallstones are more common among women than men and occur more commonly after the age of 40. [2] Gallstones occur more frequently among certain ethnic groups than others. [2]
