Q

What are the major risk factors for ASCVD?

A

Age: worse with age
Gender: ASCVD is the leading cause of death in men and women, but the age-related increase in risk begins 10 years earlier in men than in women (over 45 for men, over 55 for women)
HTN: regardless of how well it is controlled
Systolic BP: most recent value is a risk factor alone used in several predictive formulas
Cholesterol: High total and low HDL lead to increased risk
DM: High risk
Smoking: Single greatest environmental factor

Q

What does the AHA recommend as far as the heart benefits of drinking alcohol?

A

It does not currently recommend any form of alcohol in order to get the benefits for the heart.
One reason is that you cannot predict who will have difficulty with alcohol dependance and it is therefore better to not encourage anyone to start drinking.

Q

What has research shown as far as the health benefits of red wine daily?

A

Some studies have shown a decrease in mortality due to heart conditions in those drinking wine. However, it is unclear whether this benefit is truly from the alcohol, or if it is from flavonoids and other antioxidants or from other lifestyle factors like diet and exercise.
There is no clear conclusive evidence that wine is a positive thing for the heart.

Q

Special considerations for ARB’s

A

Reduces micro and macroalbuminuria
Heart remodeling effects
Avoid in pregnancy
Less bradykinin production

116

A

Can be useful in Raynaud’s
Can help some arrhythmias

Only used for hard to control patients as adjunct therapy

120
