Heart-healthy lifestyle changes can help prevent and manage small vessel disease. If you're diagnosed with small vessel disease, you'll need regular checkups with your health care provider. This drug is typically prescribed to lower blood sugar in people with diabetes, but it can improve blood vessel health even in those who don't have diabetes. Aspirin can limit inflammation and prevent blood clots. This medication eases chest pain by altering sodium and calcium levels. This makes it easier for the heart to pump blood. Drugs called angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs) help open blood vessels and lower blood pressure. Statins also help relax the blood vessels of the heart and treat blood vessel damage. These medications help lower bad cholesterol, which contributes to the narrowing of the arteries. Calcium channel blockers also help control high blood pressure and coronary artery spasms. These drugs relax the muscles around the coronary arteries and cause the blood vessels to open, increasing blood flow to the heart. These drugs slow the heart rate and decrease blood pressure. Nitroglycerin tablets, sprays and patches can ease chest pain by relaxing the coronary arteries and improving blood flow. Medications for small vessel disease may include: The goals of treatment for small vessel disease are to control the narrowing of the small blood vessels that can lead to a heart attack and to relieve pain. After the tracer is injected, you usually lie in a doughnut-shaped machine to have images taken of the heart. This test uses a radioactive tracer and medication to measure blood flow to the heart muscle. Dye injected through an IV in the arm or hand makes blood vessels easier to see on the CT images. You'll lie on a long table that slides through a short, tunnel-like machine (CT scanner). This other type of angiogram uses a powerful X-ray machine to produce a series of images of the heart and its blood vessels. The dye makes the arteries easier to see on X-ray images and video.Īdditional tests may be done during an angiogram to measure blood flow through the heart. Dye flows through the catheter to arteries in the heart. A long, thin flexible tube (catheter) is inserted into a blood vessel, usually in the groin or wrist, and guided to the heart. This test helps determine if the main arteries to the heart are blocked. Blood flow to the heart muscle is measured with ultrasound images (echocardiogram) or with nuclear imaging scans.Ĭoronary angiogram. Or you may be given an IV drug to stimulate the heart in a way similar to exercise. You may be asked to walk on a treadmill or pedal a stationary bike while connected to a heart monitor. A stress test measures how the heart and blood vessels respond to activity. Bioreactors systems that have been used to create fully vascularized functional tissue constructs will also be outlined. This paper addresses recent advances and future challenges in developing three-dimensional culture systems to promote tissue construct vascularization allowing mimicking blood microvessel development and function encountered in vivo. Vascularization of engineering tissue construct is one of the most favorable strategies to overpass nutrient and oxygen supply limitation, which is often the major hurdle in developing thick and complex tissue and artificial organ. Capillary and vascular networks that would mimic blood microvessel function can be used to subsequently facilitate oxygen and nutrient transfer as well as waste removal. Some research efforts have been made to develop methods to promote capillary networks inside engineered tissue constructs. ![]() The guidance of endothelial cell organization into a capillary network has been a long-standing challenge in tissue engineering.
