Insights
Metabolic syndrome components like visceral obesity and dyslipidemia, specifically high triglycerides and low HDL cholesterol, are linked to poor blood pressure control in hypertensive patients. Impaired glucose tolerance is not the primary driver of this resistance to treatment.
Area of Science:
- Cardiology
- Endocrinology
- Metabolic Disorders
Background:
- Hypertensive patients with metabolic syndrome or diabetes exhibit worse blood pressure control.
- The Global Cardiometabolic Risk Profile in Patients with Hypertension Disease (GOOD) survey highlighted this disparity.
- This study investigates specific metabolic syndrome components contributing to poor blood pressure control.
Purpose of the Study:
- To identify which components of metabolic syndrome are most strongly associated with inadequate blood pressure control.
- To differentiate the impact of metabolic syndrome and diabetes mellitus on hypertension management.
- To guide targeted therapeutic strategies for hypertensive patients with metabolic abnormalities.
Main Methods:
- Observational, cross-sectional survey (GOOD survey) across 12 European countries.
- Inclusion of 3,280 outpatients with hypertension receiving treatment or newly diagnosed.
- Comparison of blood pressure control, BMI, waist circumference, triglycerides, and HDL cholesterol across defined patient groups.
Main Results:
- Patients with metabolic syndrome (with or without diabetes) showed the highest blood pressure values.
- Patients with diabetes mellitus alone had significantly lower blood pressure compared to those with metabolic syndrome.
- Metabolic syndrome was associated with higher BMI, waist circumference, triglycerides, and lower HDL cholesterol.
Conclusions:
- Visceral obesity and dyslipidemia (high triglycerides, low HDL cholesterol) are key drivers of antihypertensive treatment resistance.
- Impaired glucose tolerance, a component of metabolic syndrome, is not significantly associated with poor blood pressure control.
- Targeting obesity and lipid profiles may improve blood pressure management in hypertensive patients with metabolic syndrome.
Background:
The GOOD (Global Cardiometabolic Risk Profile in Patients with Hypertension Disease) survey showed that blood pressure control was significantly worse in hypertensive patients with metabolic syndrome and/or diabetes mellitus than in those with essential hypertension only. This analysis aimed to investigate which components of the metabolic syndrome are primarily associated with poor blood pressure control.
Methods:
The GOOD survey was designed as an observational cross-sectional survey in 12 European countries to assess the cardiometabolic risk profile in patients with essential hypertension. Investigators were randomly selected from a list of general practitioners (70% of investigators) and a list of specialists such as internists, cardiologists and hypertension specialists (30% of investigators). Data from 3,280 outpatients with hypertension, aged at least 30 years who were receiving antihypertensive treatment or had newly diagnosed hypertension according to the European Society of Hypertension and the European Society of Cardiology criteria, were included in the analyses. Blood pressure control, body mass index (BMI), waist circumference, serum triglycerides, total and high density lipoprotein (HDL) cholesterol measurements were compared in patients with diabetes mellitus and metabolic syndrome, with diabetes mellitus only, with metabolic syndrome only, and with neither metabolic syndrome nor diabetes mellitus.
Results:
The highest blood pressure values were found in patients with metabolic syndrome with or without diabetes mellitus. Blood pressure was significantly lower in patients with diabetes mellitus only. The highest BMI, waist circumference and serum triglycerides, and the lowest HDL cholesterol levels among the groups studied occurred in patients with metabolic syndrome, either with or without diabetes mellitus.
Conclusion:
Among the components of the metabolic syndrome, it is not impaired glucose tolerance which is associated with the poor response to antihypertensive treatment. Instead, visceral obesity and dyslipidemia components of the metabolic syndrome, i.e. hypertriglyceridemia and low HDL cholesterol levels, are associated with resistance to antihypertensive treatment.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
