The pulmonary embolism rule-out criteria (PERC) helps assess people in whom pulmonary embolism is suspected, but unlikely. Unlike the Wells score and Geneva score , which are clinical prediction rules intended to risk stratify people with suspected PE, the PERC rule is designed to rule out the risk of PE in people when the physician has already ...
The symptoms/signs of pulmonary heart disease (cor pulmonale) can be non-specific and depend on the stage of the disorder, and can include blood backing up into the systemic venous system, including the hepatic vein. [7] [8] As pulmonary heart disease progresses, most individuals will develop symptoms like: [1] Shortness of breath; Wheezing ...
Pulmonary embolism similarly presents with shortness of breath and hypoxia. Chest pain worse with inspiration is frequently seen. Chest pain can also be similar to a heart attack. This is due to the right ventricular stress and ischemia that can occur in PE. [13] Other symptoms are syncope and hemoptysis. [14] DVT is a common cause.
Pulmonary embolism is thromboembolism of the lungs, hindering oxygenation and return of blood to the heart. Aortic stenosis hinders circulation by obstructing the cardiac output . Hypertrophic sub-aortic stenosis is overly thick ventricular muscle that dynamically occludes the ventricular outflow tract .
In the emergency department the typical approach to chest pain involves ruling out the most dangerous causes: heart attack, pulmonary embolism, thoracic aortic dissection, esophageal rupture, tension pneumothorax, and cardiac tamponade. By elimination or confirmation of the most serious causes, a diagnosis of the origin of the pain may be made.
Coronary sinus thrombosis as a severe complication after procedures. [8] The coronary sinus is the venous counterpart to the coronary arteries, where de-oxygenated blood returns from heart tissue. A large thrombus here slows overall blood circulation to heart tissue as well as may mechanically compress a coronary artery. [8]
Myocardial infarction complications may occur immediately following a myocardial infarction (heart attack) (in the acute phase), or may need time to develop (a chronic problem). After an infarction, an obvious complication is a second infarction, which may occur in the domain of another atherosclerotic coronary artery, or in the same zone if ...
Arterial occlusion can be classified into three types based on etiology: embolism, thrombosis, and atherosclerosis. These three types of occlusion underlie various common conditions, including coronary artery disease, [4] peripheral artery disease, [5] and pulmonary embolism, [6] which may be prevented by
