What occurs when there is a substantial rock on a narrow road? It hinders the flow of the site visitors causing a blockage. Now consider the arteries as the narrow road by way of which blood is supplied from the heart to the rest of the body. If the blood is hindered due to fat or calcium deposits, it could lead to blockage. This blockage can conclude into a heart attack.
Together, heart ailments and strokes account for 17.7 million deaths, across the globe1. According to the World Health Organization (WHO), India accounts for one-fifth of these deaths worldwide, particularly in the younger population. As per the National Crime Records Bureau (NCRB), the percentage of folks who died from a heart attack in 2019 saw a 53% improve from the earlier year. It’s essential to realize the illness, causes and treatments for early diagnosis and therapy.
Coronary Artery Disease
While there could be a number of causes for heart attack or failure, coronary artery illness (CAD) is the most popular cause. CAD refers to the blockage/ narrowing of the arteries in the heart. This blockage or narrowing is brought on by the buildup of fat or calcium deposits, also known as the plaque. This causes a considerable reduction in the blood flow and folks expertise mild to extreme chest discomfort or stress. If the arteries are absolutely blocked it might outcome in a heart attack. However, health-related advances have enhanced the remedies permitting CAD patients to return to a standard life-style.
Treatment possibilities for CAD:
Different remedies are advised to the patients by the cardiologist based on their health-related situations.
Medication – Some patients are prescribed drugs that relieves the chest discomfort and discomfort brought on by the blockage in the artery. However, this does not treat the blockage. Several other drugs are advised that assists in lowering cholesterol and can also be prescribed by the cardiologist, as they are blood thinners. These drugs can only aid in stopping blockage of the arteries, maintaining the contractions and rhythm of the heart as standard as feasible.
Coronary Artery Bypass Graft Surgery – Commonly identified as heart bypass or open-heart surgery is an additional therapy for CAD. The surgeon requires a brief length of the artery from the inner chest and vein from the leg and surgically attaches it above or under the blocked region of the heart artery, enhancing the blood flow to the heart. However, bypass surgery carries dangers like excessive bleeding, arrhythmia, blood clots, and infection. It might also bring about kidney failure.
Angioplasty with Coronary Artery Stenting – Under this process a little mesh tube, known as the stent, is implanted into the artery to widen the artery and guarantees sufficient blood flow to the heart. The stent is left in the artery to preserve it open and aid in stopping additional narrowing of the artery. Angioplasty is one of the most common techniques to treat CAD. However, it is essential to note that this therapy is only recommended soon after obtaining diagnosed by way of – Coronary Angiography and Intravascular Ultrasound (IVUS).

How is IVUS distinctive from Angiography?
Angiography is a diagnostic process that identifies the illness in the walls of coronary arteries. IVUS is an imaging approach which makes it possible for the medical doctor to have a detailed look into the blood vessels of the heart, from inside out. Hence, angiography supplies a two-dimensional image and IVUS presents a 3-dimensional detailed image of all the layers of the blood vessels.
The very sophisticated HD IVUS method functions on the principle of ultrasound waves. It comprises the catheter, a tube equipped with a unique probe or camera at one finish which has ultrasound properties to capture the image of the inner aspect of blood vessels on a genuine-time basis. The other finish of the tube is attached to a machine which converts the image captured by way of the ultrasound mechanism and displays them on a monitor, supplying the surgeon a total 360-degree internal view and far higher clarity.
While Angiography shows the narrowing of the blood vessel, it does not aid in giving any info about the nature of the blockage or the composition of the plaque. IVUS on the other hand, supplies the medical doctor with important clinical info which assists in identifying the blockage and deciding upon the proper therapy strategy. It also enables one to select the ideal size of the stent and confirms the stent placement to lessen the future dangers. It is essential to note that IVUS is accomplished in conjunction with angiography and not as its replacement.
