For the low risk patients with stable CAD to reduce ischemic
events: medical therapy = PCI.
For the high risk patients with stable multivessel coronary
disease, their symptoms can be relieved significantly through
PCI, but the long-term survival advantage from PCI is unclear.

Cardiovascular disease prevention
European Heart Jorunal (2012) 33,1635-1701
![Page 15: Stable Coronary Artery Disease: Revisiting and Cardiac Catheterization Revascularization; Which is Appropriate? Cardiology Division The First Affiliated.](https://reader031.fdocuments.net/reader031/viewer/2022013004/56649e225503460f94b0f7e9/html5/thumbnails/15.jpg)
CVD prevention is defined as a co-ordinated set of actions, at public and individual level, aimed at eradicating, eliminating, or minimizing the impact of CVDs and their related disability.
The bases of prevention are rooted in cardiovascular epidemiology and evidence-based medicine.
What is prevention ?
European Heart Jorunal (2012) 33,1635-1701
![Page 16: Stable Coronary Artery Disease: Revisiting and Cardiac Catheterization Revascularization; Which is Appropriate? Cardiology Division The First Affiliated.](https://reader031.fdocuments.net/reader031/viewer/2022013004/56649e225503460f94b0f7e9/html5/thumbnails/16.jpg)
Atherosclerotic CVD, especially CHD, remains the leading cause of premature death worldwide.
CVD affects both men and women; of all deaths that occur before the age of 75 years in Europe, 42% are due to CVD in women and 38% in men.
Prevention works: >50% of the reductions seen in CHD mortality relate to changes in risk factors, and 40% to improved treatments.
Why is needed ?
European Heart Jorunal (2012) 33,1635-1701
![Page 17: Stable Coronary Artery Disease: Revisiting and Cardiac Catheterization Revascularization; Which is Appropriate? Cardiology Division The First Affiliated.](https://reader031.fdocuments.net/reader031/viewer/2022013004/56649e225503460f94b0f7e9/html5/thumbnails/17.jpg)
Percentage of the decrease in deaths from coronary heart disease attributed to treatments and risk factor
changes in different populations

• Preventive efforts should be lifelong, from birth (if not before) to old age.
• Population and high-risk preventive strategies should be complementary an approach limited to high-risk persons will be less effective.
• Population education programmes are still needed.
European Heart Jorunal (2012) 33,1635-1701
![Page 19: Stable Coronary Artery Disease: Revisiting and Cardiac Catheterization Revascularization; Which is Appropriate? Cardiology Division The First Affiliated.](https://reader031.fdocuments.net/reader031/viewer/2022013004/56649e225503460f94b0f7e9/html5/thumbnails/19.jpg)
Recommendations regarding risk estimation
Recommendations Class Level GRADE
Total risk estimation using multiple risk factors(such as SCORE) is recommended for asymptomatic adults without evidence of CVD.
I C Strong
High-risk individuals can be detected on the basis of established CVD,diabetes mellitus, moderate to severe renal disease, very high levels of individual risk factors, or a high SCORE risk, and are a high priority for intensive advice about all risk factors.

How can CVD prevention be applied ?

Where prevention programmes should be provided ?Recommendations on programme provision Class Level GRADE
Actions to prevent CVD should be incorporated into everyone’s daily lives, starting in early childhood and continuing throughout adulthood and senescence.
IIa B Strong
Recommendations on nurse-co-ordinated care Class Level GRADE
Nurse-coordinated prevention programmes should be
well integrated into healthcare systems.
IIa B Strong
Recommendations on self-help programmes Class Level GRADE
All patients with CVD must be discharged from hospital with clear guideline-orientated treatment recommendations to minimize adverse events.
I B Strong
Recommendations for specialized prevention centres
Class Level GRADE
All patients requiring hospitalization or invasive intervention after an acute ischemic event should participate in a cardiac rehabilitation programme to improve prognosis by modifying lifestyle habits and increasing treatment adherence.

Narrowing the gap in health inequalities. Cost savings from the number of CVD events avoided. Preventing other conditions such as cancer, pulmonary diseases, and type 2
diabetes. Cost savings associated with CVD such as medications, primary care visits,
and outpatient attendances. Cost savings to the wider economy as a result of reduced loss of production
due of illness in those of working age, reduced benefit payments, and reduced pension costs from people retiring early from ill health.
Improving the quality and length of people’s lives.
