The new clinical results from multiple studies show that the death of coronary heart disease associated with tobacco use is expected to increase up to 40% over the next five years and people with hemp use disorder are 50% more likely to experience cardiogenic shock, acute myocardial infarction. These studies were presented today at the Cardiovascular Angiography and Interventions Company (SCAI) 2025 scientific sessions.
Tobacco and cannabis are two of the most used substances in the United States, with 22 % of Americans aged 12 years or older reporting any use of tobacco in the past and 13.0 % report any use of cannabis in the past month. As the increase in use continues, more research is needed to understand the impact and better inform patients.
Despite large public health campaigns to raise awareness of tobacco and hemp damage, use is still common as we continue to see their effects on cardiovascular health. This new study presented at Scai 2025 scientific sessions is vital to the quantification of tobacco load and cannabis use in some communities, causing customized action and additional training for patients who need it most. “

Risk associated with the use of tobacco to increase at significant rate: black women and American Indians more at risk
Ischemic heart disease, also known as coronary heart disease, is a condition where the heart weakens due to reduced blood flow from narrow or blocked coronary arteries. Studies have linked the use of Tobacco to the mortality and morbidity associated with ischemic disease. Subsequently, government and public health organizations have launched campaigns to raise awareness and reduce deaths associated with tobacco use.
Researchers have analyzed national CDC-Wonder data from 1999-2020 for the mortality of ischemic heart disease-related tobacco use (IHD-T) in people aged 25 years or older. The mortality rate per 100,000 and annual and average annual percentage changes (APC, AAPC) were analyzed to identify trends and calculate projections by 2030.
In 1999, 4,669 deaths occurred compared to IHD-T, increasing 14 times to 56,367 deaths by 2020. The data provided for by 43.7% in deaths associated with IHD-T by 2030 (80,985). While female mortality trends were reduced in 2005 (APC 2.68) and in 2015 (APC 0.53), males saw the opposite with a sharp increase in deaths by 2005 (APC 40.39). The American Indians/Alaska, the black Americans and the Asian/Pacific Islands groups saw a sharp early increase in mortality rates, with annual changes of over 30%, before finally the rates. Overall, mortality rates continued to increase steadily in all racial groups, with average annual increases of over 10%. However, in women, black women saw an average annual increase of 10.39%and whites saw the highest an average annual increase of 12.01%.
“Ischemic tobacco -related ischemic heart disease is not just a problem of the past, it is still a major cause of death today, our analysis has found that the risks are not uniformly distributed, as black women face the highest annual increases. Health Oakland in Pontiac, Mich.

Data reveals heart failure patients with 50% cannabis use disorder more likely to experience heart attack
Cannabis use disorder (CUD) is a condition where individuals have a problematic standard of cannabis use, leading to discomfort or damage to everyday life and effects. As the situation becomes more widespread, this analysis aims to understand the connection of hospital entrances and the CUD.
Through the national data on the sample of internal patients (NIS) from 2016 to 2020, researchers identified patients accepted by HF and dispersed the population into two groups based on the secondary diagnosis of the CUD. The risk of mortality and nursing complications in the HF/CUD group were analyzed and compared to the HF/Non-Cud team.
The analysis revealed patients with HF and CUD at greater risk of serious cardiovascular events. Retrospective data found that 1,372,419 patients were admitted to HF during the study, with 19,445 (1.4%) of CUD patients. While the HF/CUD group showed a higher chance of cardiogenic shock (27% more likely), acute myocardial infarction (50% more likely) and arrhythmias (48% more likely) compared to the HF/non-cud group, they also revealed lower mortality (50% lesser).
“We were surprised to discover people with hemp use disorder and heart failure are at a lower risk of mortality than those without the disorder,” said Syed Ishaq, MD, an internal medicine living at Sinai Hospital in MD and MD. “However, despite the lower chance of death, they are significantly more likely to develop other relevant cardiovascular conditions such as heart attack or irregular heartbeat.
Additional study in patients with HF with accompanying substance use disorder is justified.
