Smoking Is Even More Damaging to the Heart , According to a new study presented at the European Society of Cardiology’s ESC Congress 2022, smokers have weaker hearts than non-smokers. The research found that the more people smoked, the worse their heart function became. Fortunately, some function was restored when people kicked the habit.

Smoking Is Even More Damaging to the Heart Than Thought

Smoking Is Even More Damaging to the Heart, “It is well known that smoking causes blocked arteries, leading to coronary heart disease and stroke,” said study author Dr. Eva Holt of Herlev and Gentofte Hospital, Copenhagen, Denmark. “Our study shows that smoking also leads to thicker, weaker hearts. It means that smokers have a smaller volume of blood in the left heart chamber and less power to pump it out to the rest of the body. The more you smoke, the worse your heart function becomes. The heart can recuperate to some degree with smoking cessation, so it is never too late to quit.” Tobacco kills more than eight million people each year, according to the World Health Organization (WHO). Cigarette smoking is responsible for 50% of all avoidable deaths in smokers, with half of these due to atherosclerotic cardiovascular diseases such as heart attack and stroke. Smoking Is Even More Damaging to the Heart, The detrimental effects of smoking on the arteries and arterial diseases such as heart attack and stroke are well established.Additionally, studies have shown that smoking is associated with a higher risk of heart failure, where the heart muscle does not pump blood around the body as well as it should, usually because it is too weak or stiff. This means that the body does not receive the oxygen and nutrients it needs to function normally. The link between smoking and heart structure and function has not been fully investigated. Therefore, this study explored whether smoking was related to changes in the structure and function of the heart in people without cardiovascular disease, and the effect of changing smoking habits.

Smoking Is Even More Damaging to the Heart, The 5th Copenhagen City Heart Study, which investigated cardiovascular risk factors and diseases in the general population, provided data for the study. A total of 3,874 participants aged 20 to 99 years without heart disease were enrolled. A self-administered questionnaire was utilized to obtain information on smoking history and to estimate pack-years, or the total amount of cigarettes smoked throughout the course of a person’s lifetime. 20 cigarettes smoked per day for a year constitutes one pack-year. Study participants had an ultrasound of the heart, called echocardiography, which provides information about its structure and how well it is working. The scientists compared the echocardiography measures of current smokers versus never smokers after adjusting for age, sex, body mass index, high cholesterol, hypertension, diabetes, and lung function. The average age of participants was 56 years old and 43% were women. Nearly one in five participants were current smokers (18.6%), while 40.9% were former smokers and 40.5% had never smoked. Compared to never smokers, current smokers had weaker, thicker, and heavier hearts. Increasing pack-years were associated with pumping less blood. Dr. Holt explained: “We found that current smoking and accumulated pack-years were associated with worsening of the structure and function of the left heart chamber – the most important part of the heart. Furthermore, we found that over a 10-year period, those who continued smoking developed thicker, heavier, and weaker hearts that were less able to pump blood compared to never smokers and those who quit during that time.” She concluded: “Our study indicates that smoking not only damages the blood vessels but also directly harms the heart. The good news is that some of the damage is reversible by giving up.
