The frequency and force of the hearts contractions adjust depending on the needs of the body. The heart is critical in getting oxygen and nutrients around the body and achieves this by generating the pressure for blood to circulate around the body, ensuring blood only flows in one direction. 13, 14The Australian Heart Foundation recommends having no more than two standard drinks on any day, as studies have found the consumption of more than two standard drinks a day can see an immediate increase in blood pressure, and increases the risk of developing hypertension. 12High blood pressure can cause hardening and thickening of the arteries, and is a risk factor for heart attack and stroke. It is likely there are multiple mechanisms which cause alcohol to raise blood pressure, 11 and studies have shown that a reduction in alcohol intake can lower blood pressure. 10Drinking alcohol on a single occasion can see a temporary increase in blood pressure, and regularly drinking alcohol above the national guidelines can cause alcohol-caused hypertension (high blood pressure). High blood pressure is when the blood is pumping with more force than normal through the arteries. 8īlood pressure is a measure of the force blood places against blood vessel walls. 6, 7Complications due to regular episodes of tachycardia, do vary depending on their frequency, length and severity, but it can cause blood clots that can lead to a heart attack or stroke. Studies have found that regular heavy drinking can cause episodes of tachycardia (increased heart rate due to problems in the electrical signals that produce a heartbeat). Alcohol can cause variability in the way the heart beats – the time between heart beats. Heart rate is the number of times the heartbeats per minute. All of which can increase the risk of alcohol-caused heart attack and stroke. In the long-term, drinking above the guidelines can lead to on-going increased heart rate, high blood pressure, weakened heart muscle and irregular heartbeat. At the time of drinking, alcohol can cause a temporary increase in heart rate and blood pressure. The cardiovascular system is affected by alcohol. 2 The blood delivers nutrients and other materials to all parts of the body, including alcohol, which is absorbed directly into the blood stream mainly via the stomach and small intestine. 1Blood is pumped around the body by the heart, via these blood vessels through arteries, capillaries and veins. The heart and blood vessels form part of the cardiovascular system. How alcohol can damage the cardiovascular system Alcohol consumption increases an individual's risk of cardiovascular disease.
