New clinical evidence presented at the Society for Cardiovascular Angiography & Interventions (SCAI) 2025 Scientific Sessions has drawn renewed attention to the growing cardiovascular risks associated with two of the most widely used substances in the United States: tobacco and cannabis. According to researchers, coronary heart disease deaths tied to tobacco use are projected to increase by nearly 44% within the next five years, while people with cannabis use disorder (CUD) are significantly more likely to suffer from serious heart complications including heart attacks and arrhythmias.

Disruptions to the body’s internal clock — known as circadian rhythms — may significantly elevate the risk of premature death, according to a major new study published in Scientific Reports. Researchers analyzing data from large-scale U.S. and Chinese populations found that adults aged 40 and over with disrupted circadian rhythms faced heightened mortality from cardiovascular, metabolic, renal, and neurodegenerative diseases.

The United States is inching dangerously close to a public health crisis as falling childhood immunization rates threaten to make measles endemic once again, scientists warn. A new study by researchers at Stanford University’s School of Medicine has modeled the long-term impact of declining vaccine coverage, revealing stark predictions if current trends persist.
