Study finds smoking damages heart more than thought

Smokers have weaker hearts than non-smokers, and the more smokers, the worse their heart function, new research finds. Studies have found that the more people smoke, the worse their heart function. Fortunately, when people kick the habit, some functions are restored. Smoking is known to cause clogged arteries, leading to coronary heart disease and stroke, according to new study author Eva Holt, PhD, of the Herlev and Gentofte Hospitals in Copenhagen, Denmark, presented at the European Society of Cardiology Congress in 2022. Our research shows that smoking can also cause the heart to thicken and weaken. This means that smokers have less blood in the left ventricle and less force to pump it to the rest of the body. The more you smoke, the worse your heart functions. The heart can recover to some extent after quitting smoking, so it is never too late to quit smoking. According to the World Health Organization (WHO), tobacco kills more than 8 million people every year. Smoking accounts for 50% of all avoidable deaths among smokers, half of which are due to atherosclerotic cardiovascular disease such as heart attack and stroke adverse effects have been recognized. Additionally, studies have shown that smoking is associated with a higher risk of heart failure, in which the heart muscle doesn't pump blood around the body as well as it should, usually because it's too weak or too stiff. This means that the body cannot get the oxygen and nutrients it needs to function properly. The link between smoking and cardiac structure and function has not been fully investigated. Therefore, this study examined whether smoking is associated with changes in heart structure and function in people without cardiovascular disease, and the effects of changing smoking habits. The fifth Copenhagen Heart Study provided data for the study, which investigated cardiovascular risk factors and disease in the general population. A total of 3,874 participants aged 20 to 99 without heart disease were included in the study. A self-made questionnaire was used to obtain information on smoking history and to estimate pack-years, or the total number of cigarettes smoked in a person's lifetime. Smoking 20 cigarettes a day makes up a pack year. The average age of the participants was 56 years, and 43 percent were women. Nearly one-fifth of the participants were current smokers (18.6%), while 40.9% were former smokers and 40.5% had never smoked. Current smokers have weaker, thicker and heavier hearts than never smokers. Increased smoking years were associated with decreased blood pumping. The researchers found that current smoking and cumulative smoking years were associated with deterioration in the structure and function of the left ventricle, the most important part of the heart. In addition, the study found that over a 10-year period, the hearts of those who continued to smoke became thicker, heavier, and weaker, pumping more blood compared to those who never smoked and those who quit during that time. less capable.
