Koronáriavizsgálatokat

Koronáriavizsgálatokat refers to diagnostic procedures used to examine the coronary arteries, the blood vessels that supply oxygen-rich blood to the heart muscle. These examinations are crucial for detecting and assessing conditions like coronary artery disease (CAD), which is characterized by the buildup of plaque in these arteries, leading to narrowed or blocked vessels.

Several methods are employed for koronáriavizsgálatokat. One common non-invasive technique is the electrocardiogram (ECG), which records the electrical activity of the heart and can indicate problems with blood flow. Stress tests, also known as exercise ECGs, involve monitoring the heart's response to physical exertion, often on a treadmill, to identify abnormalities that may not be apparent at rest. Another non-invasive approach is cardiac CT angiography, which uses X-rays and a contrast dye to create detailed images of the coronary arteries, revealing blockages or narrowing.

More invasive procedures include coronary angiography, often referred to as cardiac catheterization. This involves inserting a thin, flexible tube (catheter) into a blood vessel, usually in the groin or arm, and guiding it to the coronary arteries. A contrast dye is injected through the catheter, and X-ray imaging (fluoroscopy) captures the flow of blood, highlighting any obstructions. This procedure can also be used for treatment, such as performing angioplasty and stenting to open blocked arteries. Echocardiography, which uses ultrasound waves to create images of the heart, can also provide information about the heart's structure and function, indirectly assessing the impact of coronary artery issues. The choice of investigation depends on the patient's symptoms, medical history, and the suspected severity of the condition.
