Renal artery stenosis is a common cause of secondary hypertension with a rising incidence due to systemic atherosclerosis in an aging population. Patients with renovascular disease complicated by refractory hypertension, acute pulmonary edema, or progressive renal dysfunction benefit from aggressive medical therapy and may be considered for renal revascularization. Atherosclerotic renal artery ...
Once the diagnosis of pulmonary arterial hypertension is established, wheezing and chronic cough are rarely described during the course of the disease. The present study reports on two nonsmoking patients with severe pulmonary arterial hypertension, confirmed by right-heart catheterisation, who developed chronic cough, wheezing and irreversible obstructive lung disease masquerading as adult-ons...
Percutaneous renal sympathetic denervation by radiofrequency energy has been reported to reduce blood pressure (BP) by the reduction of renal sympathetic efferent and afferent signaling. We evaluated the effects of this procedure on BP and sleep apnea severity in patients with resistant hypertension and sleep apnea. We studied 10 patients with refractory hypertension and sleep apnea (7 men and ...
BACKGROUND Angiotensin II receptor blocker (ARB) as a first-line drug for hypertension in diabetes often fails to control blood pressure adequately. The objective of the study was to evaluate the effect of amlodipine combined therapy on home blood pressure (HBP) useful for management of hypertension. METHODS AND RESULTS A total of 263 type 2 diabetes with hypertension refractory to standard d...
Secondary hypertension is the most frequent form of hypertension in children. Renovascular disease accounts for 5-10% of all childhood hypertension and should be suspected in the presence of severe hypertension found difficult to manage with medical therapy. Uncontrolled hypertension can lead to severe target organ damage. We describe the case of a 13-month-old baby boy with failure to thrive, ...
We have shown previously that inhibition of small conductance Ca -activated K (SK) channels is antiarrhythmic in models of acutely induced atrial fibrillation (AF). These models, however, do not take into account that AF derives from a wide range of predisposing factors, the most prevalent being hypertension. In this study we assessed the effects of two different SK channel inhibitors, NS8593 a...
BACKGROUND A significant number (20% to 40%) of hypertensive patients with renal artery stenosis will not have blood pressure improvement after successful percutaneous revascularization. Identifying a group of patients with refractory hypertension and renal artery stenosis who are likely to respond to renal stent placement would be beneficial. METHODS AND RESULTS Brain natriuretic peptide (BN...
Although hypertension is the most prevalent risk factor for atrial fibrillation, there is currently no information available from animal models of hypertension regarding the development of atrial remodeling or increased susceptibility to atrial tachyarrhythmia. Therefore, we examined the susceptibility to atrial tachyarrhythmia and the development of atrial remodeling in excised perfused hearts...
