Treatment of Coronary Artery Stenosis

We have been hearing a lot about the rapid advancements and changes in the field of medical technology ranging from patient registration to data assessment and diagnostic methods to surgical procedures. Yet, some diseases continue to remain as a dreadful term for us; heart disease is a case in point. Coronary Heart Disease (CAD) also known as Coronary Artery Disease (CAD) is the most common type of heart disease that kills more people than any other disease across the world. The main cause of CAD is atherosclerosis (hardening of arteries). Build-up of calcium and cholesterol on the walls of coronary arteries cut down the blood supply to the heart muscles, thereby leading into cardiac ischemia or myocardial infarction (heart attack) among CAD patients.

Severe chest pain or discomfort, also termed as angina pectoris is one of the major coronary heart disease symptoms. The pain can be localised to shoulders, arms, neck, jaw or back. Though, in some cases people also experience nausea, shortness of breath and dizziness. The sensation of discomfort experienced during myocardial ischemia or myocardial infarction develops as a result of coronary artery stenosis. As the degree of coronary artery stenosis increases, myocardial blood flow is reduced resulting in severe chest pain.

Treatment plans differ according to the types of angina, which includes stable angina, unstable angina (UA), variant angina and microvascular angina. When stable angina follows a regular pattern, UA typically occurs when a person is at rest which demonstrates its highest unpredictability and risky nature. On the other hand, variant angina is a rare kind induced due to spasm in the coronary artery and can be treated with medical therapy. Severe pain persists for a long time when it comes to microvascular angina. Patients admitted with coronary heart disease symptoms are advised to undergo different laboratory tests and imaging studies to devise a treatment plan.  

Surgical intervention or medical therapy is the preferred treatment approach to tackle coronary artery stenosis. However, interventional cardiologists find it challenging to deal with coronary bifurcation lesions (a lesion in the parent coronary artery very close or involving a significant side branch) that increases the procedural complexity. An optimal surgical or medical approach for managing coronary artery bifurcation lesions is still on debate as it involves restoring lumen of both the vessels. Time is the main factor in managing angina; hence it is essential to make a quick and safe decision based on the results.

Fractional Flow Reserve Measurement and Optical Coherence Tomography in Guiding Coronary Interventions

Blockage of oxygen-rich blood supply to the heart due to the plaque build-up in coronary arteries is the primary cause for heart attacks. Termed as Coronary Artery Disease (CAD), this heart problem occurs due to a condition called atherosclerosis.  In some cases, plaque build-up is not just limited within a single epicardial vessel but to multiple vessels known as Multi vessel CAD or coronary multivessel disease. If defined in medical terms - "a condition where 70% or greater stenosis is affected in at least one major epicardial vessel and 50% or greater stenosis is affected in at least other major vessels".

Though coronary angiography has been considered as the ‘gold standard’ for diagnosing ischemic heart conditions, it has many limitations. It often failed in providing comprehensive and accurate information about the physiological significance of lesions. That is when the well-validated Fractional Flow Reserve measurement came into the limelight. Performed along with the cardiac angiogram, it has been proved as a safe and reliable diagnostic tool to differentiate between ischemic and non-ischemic stenosis.

On the other hand, medical imaging techniques such as Intra Vascular Ultra Sound (IVUS) and Optical Coherence Tomography (OCT) have found a place in interventional cardiology. Functional severity of stenosis, plaque morphology and intraluminal coronary dimensions are some of the many features that can be assessed with IVUS.  Whereas, OCT is slightly more efficient than the IVUS technique as it offers microscopic visualization of ten-times higher resolution. Advanced Optical Coherence Tomography technique renders clear and detailed pathophysiology of atherosclerotic plaque. 

In terms of treatment choices for multivessel diseases, we presently have surgical management and medical therapy. Revascularization methods include Percutaneous Coronary Intervention (PCI) or angioplasty and Coronary Artery Bypass Graft (CABG) or bypass surgery. Reliable Fractional Flow Reserve Measurement value along with angiographic data helps physicians decide between PCI and medical therapy for single vessel CAD. Negating the need of repeated revascularization and relieving the likelihood of angina to a greater extent, CABG appears to be a superior choice over PCI when it is concerns treating multivessel disease. However, with the advancements in catheterization, medical imaging and stenting techniques, physicians are shifting away from the aggressive bypass surgical procedures and opting for less-invasive percutaneous treatments that ensure favourable long-term outcome. Yet, the optical treatment strategy for multi vessel CAD remains a controversial topic.
