Insights
Orthostatic hypertension (OHT) is a growing concern, linked to increased risks of heart and kidney disease. Further research is needed to understand its full impact on cardiovascular disease and chronic kidney disease progression.
Area of Science:
- Cardiology
- Nephrology
- Endocrinology
Background:
- Orthostatic hypertension (OHT) is increasingly recognized in patients with borderline hypertension, diabetes, autonomic dysfunction, and the elderly.
- OHT is associated with accelerated end-organ damage, particularly coronary heart disease (CHD) and chronic kidney disease (CKD).
- The heightened risk of cardiovascular disease (CVD) and CKD associated with OHT is underappreciated.
Purpose of the Study:
- To review the clinical significance of OHT.
- To explore the association between OHT and the progression of CKD and CVD.
- To discuss the underlying mechanisms contributing to OHT and cardiorenal metabolic disease (CRS).
Main Methods:
- Literature review of existing studies on OHT, CKD, and CVD.
- Analysis of pathophysiological mechanisms linking OHT to cardiorenal outcomes.
- Synthesis of evidence regarding the clinical impact and risk stratification associated with OHT.
Main Results:
- OHT is linked to significant end-organ damage, including CKD and CHD.
- Mechanisms such as adrenergic sensitivity, baroreceptor dysfunction, and renin-angiotensin-aldosterone system activation contribute to OHT and CRS.
- Evidence suggests OHT is an independent risk factor for cardiorenal metabolic disease.
Conclusions:
- OHT poses a significant clinical challenge with underappreciated risks for CKD and CVD.
- Understanding the mechanisms of OHT is crucial for managing patients at risk of cardiorenal metabolic disease.
- Further clinical investigation is warranted to fully elucidate the impact of OHT on CKD and CVD progression.
Abstract:
Orthostatic hypertension (OHT) is a clinically important problem increasingly recognized in persons with borderline hypertension, diabetes mellitus, and autonomic neuropathies, and in the elderly. Moreover, the association of OHT with progression of target end-organ damage, especially coronary heart disease and chronic kidney disease (CKD), and the attendant increased cardiovascular disease (CVD) and CKD risk, is gaining attention but is still underappreciated. There are various mechanisms that contribute to the development of OHT: excessive vascular adrenergic sensitivity, baroreceptor reflex abnormalities, and inappropriate activation of the renin-angiotensin-aldosterone system, which are also mechanisms that lead to cardiorenal metabolic disease (CRS). While the evidence is compelling for the clinical importance of OHT, more investigation is needed to evaluate the effects of OHT on CKD and CVD. The notion that the development of OHT is a risk factor for the development of CRS raises the need for further clinical and investigational attention to this clinical dilemma.
