To decrease blood pressure, the heart can pump less forcefully or rapidly, arterioles and veins can widen (dilate), and fluid can be removed from the bloodstream. These mechanisms are controlled by the sympathetic division of the autonomic nervous system (the part of the nervous system that regulates internal body processes requiring no conscious effort) and by the kidneys.

Since arterioles are blood vessels, conditions that affect the cardiovascular systemalso affect arterioles. Conditions affecting your arterioles include: 1. High blood pressure(hypertension). 2. Smoking. 3. High cholesterol. 4. Chronic obstructive pulmonary disease(COPD). 5. Inflammatory bowel disease. 6. Thrombosis (blood clots). 7. Arthritis. 8. ...
Your healthcare provider can use the following imaging methods to check arterioles: 1. CT (computed tomography) angiogram. 2. MR (magnetic resonance) angiogram. 3. Doppler ultrasound.
Your healthcare provider may prescribe medicines that help your cardiovascular system — which includes your arterioles — work better. These include: 1. Antihypertensivesfor high blood pressure. 2. Cholesterol-lowering medicines. 3. Anti-inflammatory medications for conditions such as vasculitis. 4. Quitting smoking.
Aug 1, 1995 · The data on small arteries and arterioles 1 2 have been confirmed by clinical studies performed on isolated subcutaneous arterioles 3 and intramyocardial coronary arterioles. 4 The observed morphological changes have been distinguished either as “remodeling” or “hypertrophy,” depending on the decrease or increase of the external diameter, respectively. 5 6 The functional consequences ...

Mar 13, 2015 · Resistance arteries play a crucial role in the control of blood pressure (BP). The main drop in hydrostatic pressure occurs at their site. Peripheral resistance in small arteries (lumen diameter <350 μm) and arterioles (lumen diameter <100 μm) accounts for 45% to 50% of total peripheral resistance, 1 – 4 whereas capillaries (≈7 μm lumen diameter) account for 23% to 30%.

Jul 1, 1995 · Coronary occlusion with onset of myocardial infarction can come on at any time in a susceptible person but is most common soon after waking, during the arousal response, when heart rate and blood pressure are high. 24 Coronary occlusion is also more common during exercise than at rest, especially if exercise is vigorous and unaccustomed. 25 26 27 Again, these peaks correspond to increase in ...

Nov 28, 2023 · High blood pressure can cause many heart conditions, including: Coronary artery disease. High blood pressure can narrow and damage the arteries that supply blood to the heart. This damage is known as coronary artery disease. Too little blood flow to the heart can lead to chest pain, called angina.
