Increased QTc dispersion is related to blunted circadian blood pressure variation in normoalbuminuric type 1 diabetic patients.
A reduced nocturnal fall in blood pressure (BP) and increased QT dispersion both predict an increased risk of cardiovascular events in diabetic as well as nondiabetic subjects. The relationship between these two parameters remains unclear. The role of diabetic autonomic neuropathy in both QT dispersion and circadian BP variation has been proposed, but data have been conflicting. The aim of the ...
متن کاملProlonged QTc interval predicts poststroke paroxysmal atrial fibrillation.
BACKGROUND AND PURPOSE Paroxysmal atrial fibrillation (PAF) is often difficult to detect in patients with acute ischemic stroke. We aimed to assess the predictive value of a prolonged QT interval corrected for heart rate (QTc) in PAF detection after acute ischemic stroke. METHODS We enrolled 972 patients with acute ischemic stroke consecutively extracted from our observational stroke registry...
متن کاملCircadian blood pressure variation in hypertensive patients with primary hyperaldosteronism.
A less-than-normal decline in nocturnal blood pressure (BP) has been associated with excessive hypertensive complications. This is concerning because secondary hypertension is often associated with this so-called nondipper BP profile. A nondipping pattern is more frequently found in the presence of pheochromocytoma, Cushing's syndrome, and sleep apnea syndrome, but the prevalence is unclear in ...
متن کاملCircadian blood pressure variation in transgenic hypertensive rats.
Automatic, around-the-clock blood pressure measurements have increased our understanding of hypertension in humans. Patients with essential hypertension display patterns similar to those observed in normotensive subjects, whereas those with secondary hypertension frequently show abnormal circadian rhythms characterized by a failure to reduce blood pressure at night. We have modeled this situati...
متن کاملAntihypertensive Drug Therapy in Consideration of Circadian Blood Pressure Variation*
J-MUBA was a large-scale clinical study which, for the first time in the world, evaluated the effects of an antihypertensive drug on circadian BP variation in more than 600 patients with hypertension. Although ACE inhibitors reportedly exert equal 24-hour antihypertensive effects on daytime and nighttime BP, and -blockers are reported to have weaker effects on nighttime BP than on daytime BP. H...
