Researchers at The Australian National University (ANU) have confirmed that smoking triples the risk of death from heart disease. This alarming finding emerges from a massive seven-year study tracking 190,000 Australians, directly linking tobacco use to over 6,400 cardiovascular deaths annually and proving that no level of smoking is safe.
Led by Professor Emily Banks from the ANU National Centre for Epidemiology and Population Health, the research is recognized as the most in-depth global study of its kind. It is the first to map exactly how smoking damages the entire cardiovascular system, including the heart and major blood vessels.
The research team tracked participants across 36 different types of diseases. They examined the impact of smoking on men, women, urban and rural residents, and across all socioeconomic backgrounds. The conclusion was stark: smoking causes terrible harm across the board, leaving users with “nowhere to run, nowhere to hide.”
In Australia, where approximately 2.7 million people smoke, tobacco kills at least 17 individuals daily from preventable cardiovascular conditions. Furthermore, it drives 11,400 coronary heart hospitalizations every year.
| Condition / Scenario | Risk Increase (Compared to Non-Smokers) |
|---|---|
| Cardiovascular Death | Triple the risk (200% increase) |
| Heart Attack, Stroke, or Heart Failure | Double the risk |
| Peripheral Diseases (e.g., Gangrene) | Five times more likely |
| Light Smoking (5 cigarettes/day) | Double the risk of cardiovascular death |
Despite the grim statistics, the study offers a clear path forward. Researchers emphasized that quitting smoking strongly and rapidly reduces the risk of heart attacks, strokes, and cardiovascular mortality compared to continuing the habit.
The team warned that the battle against tobacco devastation is far from over, urging governments to maintain high-priority tobacco control measures. For smokers, regardless of their daily intake or how long they have smoked, the medical advice is unequivocal: the best time to stop is right now.
