A new heart disease diagnosis approach has led to a 99.1% accuracy in diagnosing heart disease. [18] This new diagnosis approach uses CT-scan imagery to focus on coronary artery diseases and blockages in contrast to angiography. [18] Further research directions in preventing and treating coronary artery disease include: [19]
Cardiac CT (CCT) is a modified form of the traditional chest CT due to the difficulty of imaging the complex, moving heart. [16] This is achieved through the use of thin slices and high-resolution scanning, as well as the addition of electrocardiogram (ECG) gating or triggering to capture a motion-free image.
The diagnosis of myocardial infarction requires two out of three components (history, ECG, and enzymes). When damage to the heart occurs, levels of cardiac markers rise over time, which is why blood tests for them are taken over a 24-hour period. Because these enzyme levels are not elevated immediately following a heart attack, patients ...
In those with severe disease a number of medications should be avoided, including ACE inhibitors, nitroglycerin, and some beta blockers. [1] Nitroprusside or phenylephrine may be used in those with decompensated heart failure depending on the blood pressure. [1] [3] Aortic stenosis is the most common valvular heart disease in the developed ...
Certain diseases such as neuroendocrine tumor of the small intestine (also known by the obsolete term carcinoid), which sometimes release large amounts of 5-hydroxytryptamine, commonly known as 5-HT or serotonin into the blood, may produce a characteristic pattern of mostly right-sided cardiac fibrosis which can be identified with echocardiography.
Hypertrophic cardiomyopathy (HCM, or HOCM when obstructive) is a condition in which muscle tissues of the heart become thickened without an obvious cause. [8] The parts of the heart most commonly affected are the interventricular septum and the ventricles. [10]
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. [3] CVDs constitute a class of diseases that includes: coronary artery diseases (e.g. angina, heart attack), heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease ...
Coronary artery disease, also known as "ischemic heart disease", [24] is a group of diseases that includes: stable angina, unstable angina, myocardial infarction, and is one of the causes of sudden cardiac death. [25] It is within the group of cardiovascular diseases of which it is the most common type. [26]
