Cardiovascular effects

Rheumatic heart disease — heart muscles and valves damage due to rheumatic fever caused by Streptococcus pyogenes a group A streptococcal infection. Risk factors There are many risk factors for heart diseases: One of them relates to serum cholesterol level.

Cardiovascular effects

THC can increase heart rate by beats per minute. This increase occurs in order to compensate for the reduction in blood pressure caused by THC. Low doses of THC appear to most strongly activate pro-cardiovascular health effects.

CBD has beneficial effects on cardiovascular risk factors and improves recovery in animal models of heart attack and stroke. An additionaldeaths result from stroke. Cannabis consumers are used to warnings about the potential damage the drug is doing to their brain, but what about their heart?

Could cannabis be affecting our cardiovascular health? In fact, the researchers found some evidence that cannabis use may be associated with lower risk for obesity.

So are cannabis consumers in the clear? The authors note that many of the studies were limited by elevated risk of bias and poor control over cannabis exposure levels and frequency.

But what caused scientists and physicians to propose a link between cannabis and cardiovascular risk factors in the first place? Most studies looking at the impact of cannabis on cardiovascular health only control for Cardiovascular effects use patterns, not type of cannabis.

Well, that sounds frightening. Some have high levels of other cannabinoidslike cannabidiol CBDwhich can have opposite effects on the brain and body as THC.

But most studies looking at the impact of cannabis on cardiovascular health only control for general use patterns, not type of cannabis.

And how often are they using? Blood pressure is lowered because THC increases the diameter of blood vessels, forcing the heart to work harder in order to pump blood.

Cannabis and Its Impact on High Blood Pressure Effects on Arteries CB1 receptor activation also increases plaque buildup in arteries, which increases risk of atherosclerosis, a disease characterized by the narrowing of arteries that can lead to heart attack and stroke.

This effect occurs through two main mechanisms. First, activating CB1 receptors increases the amount of harmful chemicals called reactive oxygen species, which damage the walls of arteries. The damage to the artery walls initiates an immune response that attracts special immune cells known as macrophages.

These macrophages become part of the wall of the artery. Elevated levels of reactive oxygen species have an exacerbated effect on plaque buildup, increasing risk of heart attack and stroke.

The Effects of CB2 Receptors on Cardiovascular Health While drugs that activate CB1 receptors can have negative effects on cardiovascular health, drugs that selectively activate CB2 receptors have beneficial effects on heart health.

Low doses of THC have been shown to reduce plaque buildup and risk for atherosclerosis. CB2 receptors are mostly expressed in immune cells, but their levels increase in other parts of the body after injury or in disease. Activating CB2 receptors reduces the inflammation and free radicals that increase plaque buildup in arteries and elevate risk for heart attack and stroke.

The answer depends on the dose. In fact, low doses of THC have been shown to reduce plaque buildup and risk for atherosclerosis. THC directly stimulates the CB1 receptor. This interaction underlies the major psychoactive effects of cannabis consumption.

On its own, CBD is a potent antioxidant and neutralizes harmful free radicals.

It also has strong anti-inflammatory abilities which can reduce the damage caused by activation of CB1 receptors. Indeed, CBD has beneficial effects on cardiovascular risk factors and improves recovery in animal models of heart attack and stroke. Emerging evidence suggests that cannabis use increases risk for cardiovascular events, but these studies fail to control for THC levels consumed, the presence of additional and often counteracting cannabinoids e.

Regardless of how you interpret the risk, just be sure stay away from synthetic cannabinoids like K2 and Spice—that junk can kill you.Cardiovascular disease (CVD) is a class of diseases that involve the heart or blood vessels.

Particulate matter has been studied for its short- and long-term exposure effects on cardiovascular disease. Currently, PM is the major focus, in which gradients are used to determine CVD risk. May 30,  · Heart and blood vessel disease (also called heart disease) includes numerous problems, many of which are related to a process called atherosclerosis.

Atherosclerosis is a condition that develops when a substance called plaque builds up in the walls of the arteries. Alcohol and cardiovascular disease. Jump to navigation Jump to search.

Total recorded alcohol per capita consumption, in litres of pure alcohol. many physicians have been wary of promoting the use of alcohol for this benefit considering the many negative effects of excessive alcohol consumption.

At the population level, acute and chronic exposure to particle pollution can increase the numbers of cardiovascular events, including hospitalizations for serious cardiovascular events, such as coronary syndrome, arrhythmia, heart failure, and stroke, particularly in people with established heart disease.

Performance-enhancing drugs may have an effect on the cardiovascular system by means of directly altering the myocardium, vasculature, and metabolism.

However, less frequently considered is the potential for indirect effects caused through enabling athletes to push beyond normal physiological limits with the potential consequence of exercise. ![Figure][1] Cocaine is the leading cause for drug–abuse-related visits to emergency departments, most of which are due to cardiovascular complaints.

Through its diverse pathophysiological mechanisms, cocaine exerts various adverse effects on the cardiovascular system, many times with grave results.
