Angiographic studies on patients
before myocardial infarction show
that the majority of subsequent
events involve sites with < 70%
obstruction.
Falk E. et al. Circ 1995;92:657
The new picture of
atherosclerosis explains why
many heart attacks come
from out of the blue: the
plaques that rupture do not
necessarily protrude very far
into the blood channel and so
may not cause angina or
ischemic ST-segment
depression.

The Polypill as Part of a Global
Strategy to Substantially Reduce the
CVD Burden
The polypill could potentially be widely used in
secondary prevention and in selected high-risk
individuals without known CVD (e.g., those with
diabetes mellitus with additional risk factors).
In such individuals, a 50% to 75% proportional reduction
in risk can be anticipated from prolonged therapy.
By contrast, in individuals without CVD and not at high risk,
large trials are needed to quantify the benefits, potential
risks and cost-effectiveness of the polypill.
Lonn E et al. Circulation 2010;122:2078-2088
Polypill: User Directions
Take medication each day in the prescribed
dosage, followed or preceded by at least 30
minutes of moderate-to-vigorous physical
activity, in combination with a low-fat, lowcholesterol diet, weight management,
smoking cessation, and regular visits to your
physician.
Franklin BA et al. AJC 2004;94:162
Dietary Priorities Associated with
Cardioprotective Benefits
Consume more:
Consume less:
• Fish and shellfish
• Potatoes, refined grains, sugars
• Whole grains
• Processed meats
• Fruits
• Sweetened beverages, diet sodas
• Vegetables
• Grain-based desserts & bakery goods
• Nuts
• Fats, oil or foods containing partially
• Low-fat or no fat diary products
hydrogenated vegetable oils
• Vegetable oils*
• Salt
• Water
• Alcohol**
* Examples include flaxseed, canola, and soybean oil
** For adults who drink alcohol, no more than moderate consumption (i.e., up to 2
drinks/day for men, 1 drink/day for women) should be encouraged, ideally with meals.
CONCLUSIONS: Better CRF was associated with lower
risk all-cause mortality and CHD/CVD. Participants with
a MAC of 7.9 METs or more had substantially lower rates
of all-cause mortality and CHD/CVD events compared
with those with a MAC of less 7.9 METs.

Prognostic Significance of Peak Exercise
Capacity in Patients with CAD*
• 527 men with CVD who were referred
to an outpatient rehabilitation program
• Measured peak VO2 during cycle ergometer
testing
• Average follow-up of 6.1 yrs, 33 and 20 pts
died of cardiovascular and noncardiovascular
causes, respectively.
Highest mortality in pts who averaged ≤ 4.4 METs; There
were no deaths in pts who averaged ≥ 9.2 METs.

Major Findings
 Compared with usual care, CR ↓ total mortality
by 20% and cardiac mortality by 26%.
 There were also substantial ↓s in TC, TGs, SBP,
and self-reported cigarette smoking in the CR
group, but there were no differences in HDL-C
and LDL-C, DBP, or health-related QOL.
 The effect of CR on total mortality was
independent of whether the trial was published
before or after 1995, suggesting that the
mortality benefits of CR persist in modern
cardiology.
