Certain factors place us at risk for the development of cardiovascular disease.
Which of the following are modifiable risk factors? Select all that apply.

Digibind is the trade name forantidigoxin, which is an antibody made up of anti-digoxin immunoglobulin fragments.It is thespecific antidoteto digoxin toxicity, which can occur even when the serum digoxin concentration is within the therapeutic range.Digoxin toxicity causes anorexia, nausea, vomiting, neurological symptoms and arrhythmias.

Choice A, Protamine sulfate, is wrong because it is the antidote for heparin overdose, not digoxin toxicity.

Protamine sulfate reverses the anticoagulant effect of heparin by binding to it and forming a stable complex.

Choice B, Acetylcysteine, is wrong because it is the antidote for acetaminophen overdose, not digoxin toxicity.

Acetylcysteine replenishes glutathione, which is depleted by acetaminophen metabolites that cause hepatotoxicity.

Choice D, Vitamin K, is wrong because it is the antidote for warfarin overdose, not digoxin toxicity.

Vitamin K restores the synthesis of clotting factors that are inhibited by warfarin.

Normal ranges for serum digoxin concentration are 0.6 to 1.2 nanomol/L (0.5 to 0.9 nanograms/mL) for heart failure and unknown for atrial fibrillation without heart failure.

Normal ranges for serum potassium level are 3.5 to 5.0 mmol/L and for serum magnesium level are 0.7 to 1.0 mmol/L.

These are all modifiable risk factors for cardiovascular disease, meaning they can be changed through lifestyle choices or medication.Cholesterol level, blood pressure, weight, and smoking all affect the health of the heart and blood vessels, and can increase the risk of developing conditions such as atherosclerosis, hypertension, heart attack, or stroke.

Choice C, family history, is not a modifiable risk factor for cardiovascular disease.

It is a non-modifiable risk factor, meaning it cannot be changed and is determined by genetics.

Having a family history of cardiovascular disease can increase the risk of developing it, but it does not mean that it is inevitable.Other non-modifiable risk factors include sex, older age, race and ethnicity.

Some normal ranges for the modifiable risk factors are:

• Cholesterol level: total cholesterol should be less than 200 mg/dL; LDL cholesterol should be less than 100 mg/dL; HDL cholesterol should be more than 40 mg/dL for men and more than 50 mg/dL for women; triglycerides should be less than 150 mg/dL.

• Blood pressure: normal blood pressure is less than 120/80 mmHg; elevated blood pressure is 120-129/less than 80 mmHg; hypertension stage 1 is 130-139/80-89 mmHg; hypertension stage 2 is 140 or higher/90 or higher mmHg.

• Weight: body mass index (BMI) is a measure of weight relative to height; normal BMI is 18.5-24.9 kg/m2; overweight BMI is 25-29.9 kg/m2; obese BMI is 30 or higher kg/m2.

• Smoking: smoking any amount of tobacco products can harm the cardiovascular system; quitting smoking can lower the risk of cardiovascular disease and improve overall health.
