• Study Findings on Smoking & Heart Risk

• A major Johns Hopkins-led study tracked over 9,300 adults across ~13 years and found that cigarette smokers had more than double the risk of developing heart failure (both preserved and reduced ejection-fraction types) compared with never-smokers
  

• In Australia, research shows smokers face roughly twice the risk of many cardiovascular diseases, including heart attacks, strokes, and heart failure. Some conditions—like peripheral artery disease and heart failure—carry even 2–5 times higher risk .

   

   

  Broader Evidence on Heart-Related Smoking Risks

• The CDC confirms smoking raises coronary heart disease and stroke risk by 2–4×, even at low levels, and worsens blood pressure, cholesterol, and arterial health

  * Sudden cardiac death risk is elevated ~3× among current smokers compared to those who’ve never smoked, based on meta-analyses

   In women, light-to-moderate smoking is especially risky—linked to ~2–3× higher sudden cardiac death, as seen in the Nurses’ Health Study

  Why This Risk Occurs

  Smoking contributes to heart-related harm by:

• Raising heart rate and blood pressure

• Damaging blood vessel lining and increasing clot formation

• Lowering HDL (“good”) cholesterol

• Accelerating plaque build-up (atherosclerosis)

   

   Even secondhand smoke carries roughly 30% increased risk of coronary heart disease for non-smokers

   

  Bottom line:

  The claim that smoking “doubles the risk of heart-related deaths” is well-supported—with consistent evidence showing 2–4× increased risks for heart failure, coronary disease, stroke, and sudden cardiac death. Importantly, quitting smoking—even after years of use—substantially lowers risk over time.

   

   

  Tobacco related cardiovascular risks more deadly

• The Times of India article titled "Tobacco-related cardiovascular risks more deadly: Docs" highlights concerns from medical professionals who say smoking significantly increases the risk of cardiovascular deaths—often more than cancers. The piece emphasizes that even short-term or light tobacco use can double the risk of heart attacks, strokes, and related complications. Doctors urge stronger public health interventions and early cessation.

 You're absolutely right — smoking is extremely dangerous. It significantly increases the risk of:

• Heart disease and stroke

• Lung and other cancers

• Chronic obstructive pulmonary disease (COPD)

• Sudden cardiac death

• Reduced immunity and faster aging

Even exposure to secondhand smoke poses serious health threats. The good news? Quitting smoking starts reversing damage within days to weeks, and long-term benefits grow over time.
