Coronary artery disease (CAD) occurs when plaque builds up on the inner walls of the coronary arteries. This causes the arteries to harden and narrow, decreasing blood flow to the heart. As a result, the heart becomes deficient in oxygen and nutrients, which can lead to chest pain or a heart attack. CAD often develops over decades; the disease may go unnoticed until a severe blockage or heart attack occurs.
Coronary stents are small, wire, mesh tubes that help widen a clogged artery and restore adequate blood flow to the heart. During the procedure, the cardiologist will place the stent over a thin, long tube with a balloon tip, called a catheter, and insert it into an artery in the patient’s groin or arm. Once the stent reaches the clogged artery, the doctor will inflate the balloon to expand the stent. When the stent reaches the desired size to widen the clogged artery, the doctor will deflate and remove the balloon. The stent will stay in place permanently to help prop open the artery and decrease its chance of narrowing again. Over time, the inner lining of the artery will grow over the surface of the stent, making it a permanent part of the artery.
The global coronary stents market size was estimated at $8.8 billion in 2021 and is expected to grow at a compound annual growth rate (CAGR) of 3.3% from 2022 to 2030. An ageing population and a rising prevalence of risk factors such as cardiovascular diseases (CVDs), complex lesions, diabetes, obesity, and others are expected to drive demand for coronary stents over the forecast period. According to the World Health Organization (WHO), in 2019, CVDs were among the major causes of mortality worldwide. In 2019, an estimated 17.9 million people died from CVDs, responsible for 32% of all worldwide mortalities. Moreover, the rising use of tobacco and alcohol, and rising stress levels, is also a vital reason behind the rising occurrence of heart-related conditions and disorders, thereby driving the expansion of market growth. These forecast values may be subject to be affected by changes in regulation of tobacco and alcohol, the compliance of medical patients, and other stress factors.
