Management of Metabolic Syndrome

Definition and Diagnosis

The European Society of Cardiology defines metabolic syndrome as the presence of three or more of the following components: abdominal obesity, elevated triglycerides, low HDL cholesterol, elevated blood pressure, and impaired fasting glucose 1, 2
Abdominal obesity is defined as a waist circumference >102 cm in men and >88 cm in women, according to the European Society of Hypertension 2
Elevated triglycerides are defined as ≥1.7 mmol/L (150 mg/dL), as stated by the European Society of Hypertension 2
Low HDL cholesterol is defined as <1.03 mmol/L (40 mg/dL) in men and <1.29 mmol/L (50 mg/dL) in women, as defined by the European Society of Hypertension 2
Elevated blood pressure is defined as ≥130/85 mmHg, according to the European Society of Hypertension 2
Impaired fasting glucose is defined as ≥5.6 mmol/L (100 mg/dL), as stated by the European Society of Cardiology 1

The American Heart Association recommends aiming for a 7-10% reduction in body weight over 6-12 months through modest caloric reduction (500-1000 calories/day) 4
Even moderate weight loss (7-10% of body weight in 1 year) can significantly improve all components of metabolic syndrome, as reported by the American Heart Association 4
The American Diabetes Association suggests focusing on weight maintenance if weight reduction cannot be achieved 4
The European Society of Cardiology recommends reducing intake of saturated fats, trans-fatty acids, cholesterol, and simple carbohydrates, and increasing consumption of fruits, vegetables, whole grains, and lean proteins 5
The American Heart Association advises restricting sodium to less than 2g/day in patients with hypertension, as stated by the European Society of Hypertension 2
The European Society of Cardiology recommends implementing at least 30 minutes of moderate-intensity physical activity daily, aiming for 150 minutes weekly of moderate physical activity, and combining aerobic exercise with strength training for optimal results 6
The American Heart Association suggests decreasing sedentary behaviors such as television watching and screen time, as reported by the European Society of Hypertension 2

The European Society of Cardiology recommends beginning with a renin-angiotensin system blocker (ACE inhibitor or ARB) when BP exceeds 140/90 mmHg, as stated by the European Society of Hypertension 2
The American Heart Association suggests targeting blood pressure <130/80 mmHg, as reported by the European Society of Cardiology 1
The European Society of Cardiology advises avoiding beta-blockers unless specifically indicated due to their adverse effects on glucose metabolism, as stated by the European Society of Hypertension 3
The American College of Cardiology recommends statins as first-line therapy for elevated LDL cholesterol, as reported by the European Society of Cardiology 7
The European Society of Cardiology suggests targeting LDL cholesterol <2.5 mmol/L (100 mg/dL), as stated by the European Society of Cardiology 1
The American Diabetes Association recommends metformin for patients with impaired glucose tolerance or diabetes, as reported by the European Society of Cardiology 3

The European Society of Cardiology recommends addressing all components simultaneously for maximum cardiovascular risk reduction, as stated by the American Heart Association 3
The American Heart Association suggests regular monitoring of metabolic parameters, including lipid profile, blood pressure, and glucose levels, as reported by the European Society of Cardiology 6
The European Society of Cardiology advises assessing for subclinical organ damage, including microalbuminuria and left ventricular hypertrophy, as stated by the American Heart Association 3
The American Heart Association recommends using ambulatory and home blood pressure monitoring for accurate assessment, as reported by the European Society of Cardiology 3

The European Society of Cardiology states that metabolic syndrome increases the risk of fatal coronary heart disease 4-fold in men and 2-fold in women, as reported by the European Society of Hypertension 2
The American Heart Association reports that patients with metabolic syndrome have a 5-9 fold increased risk of developing diabetes, as stated by the European Society of Hypertension 2

The European Society of Cardiology recommends combination therapy with a renin-angiotensin system blocker and calcium antagonist, which has shown a lower incidence of diabetes than conventional treatment with beta-blockers, as reported by the American Heart Association 3
The American Heart Association suggests considering diuretics, SGLT2 inhibitors, and ACE inhibitors in patients with heart failure and chronic kidney disease, as stated by the European Society of Cardiology 6
The European Society of Cardiology advises regular monitoring of renal function, albuminuria, serum potassium, and natriuretic peptides, as reported by the American Heart Association 6
