The disease is commonly asymptomatic and is normally discovered when performing tests for other conditions such as coronary artery disease, stable angina and other acute coronary syndromes. [2] [3] Coronary artery ectasia occurs 4 times more frequently in males than in females and in people who have risk factors for heart disease such as smokers.
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]
In difficult cases or in situations where intervention to restore blood flow is appropriate, coronary angiography can be performed. A catheter is inserted into an artery (typically the radial or femoral artery [21]) and pushed to the vessels supplying the heart. A radio-opaque dye is administered through the catheter and a sequence of x-rays ...
Coronary CT angiography (CTA or CCTA) is the use of computed tomography (CT) angiography to assess the coronary arteries of the heart.The patient receives an intravenous injection of radiocontrast and then the heart is scanned using a high speed CT scanner, allowing physicians to assess the extent of occlusion in the coronary arteries, usually in order to diagnose coronary artery disease.
An imaging dye is loaded into the blood vessel through the catheter and the movement of the dye in the blood vessel is recorded as an angiogram. [18] Doctors could determine if there are any abnormalities in the blood vessel using fluoroscopy, computed tomography (CT) angiography or magnetic resonance (MR) angiography. After the catheter is ...
Treatment aims to preserve as much heart muscle as possible, and to prevent further complications. [28] Treatment depends on whether the myocardial infarction is a STEMI or NSTEMI. [72] Treatment in general aims to unblock blood vessels, reduce blood clot enlargement, reduce ischemia, and modify risk factors with the aim of preventing future ...
A heart attack can cause arrhythmias, as well as permanent damage to the heart muscle. [25] Coronary ischemia resulting from coronary artery disease also increases the risk of developing heart failure. [10] Most cases of heart failure result from underlying coronary artery disease. [10]
Radionuclide angiography is an area of nuclear medicine which specialises in imaging to show the functionality of the right and left ventricles of the heart, thus allowing informed diagnostic intervention in heart failure. It involves use of a radiopharmaceutical, injected into a patient, and a gamma camera for acquisition.
