Insights
Many heart attacks and strokes occur in people with normal blood pressure. Identifying hidden cardiovascular risk factors and target organ damage is crucial for early intervention and preventing serious events.
Area of Science:
- Cardiology
- Hypertension Research
- Preventive Medicine
Background:
- Severe hypertension significantly increases cardiovascular disease (CVD) risk.
- A notable percentage of myocardial infarctions and strokes occur in individuals with normal or mildly elevated blood pressure.
- Coexisting risk factors (diabetes, dyslipidemia, metabolic syndrome) and target organ damage (microalbuminuria, left ventricular hypertrophy) indicate high CVD risk even with normal blood pressure.
Purpose of the Study:
- To highlight the under-recognition and undertreatment of high-cardiovascular-risk patients with normal or mildly elevated blood pressure.
- To emphasize the importance of comprehensive cardiovascular risk assessment and stratification across all blood pressure categories, as per 2003 European guidelines.
- To advocate for the identification of hidden cardiovascular risks and target organ damage to enable earlier, more effective interventions.
Main Methods:
- Review of existing literature and guidelines on hypertension and cardiovascular risk assessment.
- Analysis of the significance of combined cardiovascular risk factors and subclinical target organ damage.
- Emphasis on risk stratification strategies for individuals across the blood pressure spectrum.
Main Results:
- Subclinical target organ damage and the presence of multiple cardiovascular risk factors identify high-risk individuals even with normal or high-normal blood pressure.
- Current risk assessment often fails to recognize these high-risk individuals, leading to undertreatment.
- Early identification allows for timely antihypertensive treatment and management of all risk factors.
Conclusions:
- Comprehensive cardiovascular risk assessment, including screening for other risk factors and target organ damage, is essential for all individuals, regardless of blood pressure levels.
- Identifying high-risk patients with normal or mildly elevated blood pressure facilitates earlier intervention to prevent cardiovascular events.
- The goal is to halt or reverse silent vascular damage before clinical manifestations occur.
Abstract:
Severe or important blood pressure elevations are associated with the risk of cardiovascular disease. However, a significant proportion of myocardial infarctions and strokes occur in subjects with only slight elevations or even with normal blood pressure. Both the coexistence of other cardiovascular risk factors, such as diabetes or dyslipidemia, or those recently recognized, such as elevations of C-reactive protein or abdominal obesity and metabolic syndrome, or the presence of target organ damage, such as microalbuminuria, left ventricular hypertrophy, mild renal dysfunction or increased intima-media thickness, all indicate the existence of a high cardiovascular risk in mild hypertensives or in subjects with normal or high-normal blood pressure. Unfortunately, these high-risk patients are often not recognized and thus under-treated. The 2003 European Societies of Hypertension and Cardiology guidelines emphasize the importance of a complete risk assessment and stratification in subjects at all blood pressure categories. The search for other cardiovascular risk factors and target organ damage should be encouraged. Identification of these high-risk patients may allow an earlier indication for antihypertensive treatment and for correction of all cardiovascular risk factors. The objective would be to impair the progression or to induce the regression of silent vascular damage before a clinical event develops.
