Quitting smoking after a cancer diagnosis can deliver a big payoff for another major health concern: the risk of heart attack or stroke. Cancer patients who kept smoking had a nearly doubled risk of either of those emergencies, as well as death from cardiovascular disease, new research showed. “A cancer diagnosis is an extremely stressful life event, which often leads to significant changes in a person’s lifestyle. Smoking, in particular, is a health-related behavior that can be heavily influenced by mental distress,” said study author Dr. Hyeok-Hee Lee, of Yonsei University College of Medicine in Seoul, South Korea. For the study, published May 30 in the European Heart Journal, researchers analyzed data from a Korean national health claims database for more than 309,000 cancer survivors who had never had a heart attack or stroke. Participants had each answered questions about smoking and had health exams. The research team split participants into groups based on their change in smoking habits after receiving a cancer diagnosis. Groups were sustained nonsmokers, quitters, initiators/relapsers and continuing smokers. About 250,000 (80.9%) were sustained nonsmokers; just over 10% quit smoking; 1.5% initiated or relapsed to smoking, and 7.5% continued smoking after their cancer diagnosis. Then the researchers assessed the risk of cardiovascular events for each group during a median of 5.5 years, adjusting for other characteristics that could influence these risks.… read on > read on >
