Introduction . The COVID-19 pandemic has become a global health problem worldwide. consequences of the new coronavirus infection continue to be studied. Cardiovascular symptoms and sleep disorders are among dominant complaints in postCOVID-19 syndrome women. Aim To assess disorders, cardiovascular symptoms, body weight dynamics their statistical relationships women with post-COVID-19 syndrome. ...

The autonomic nervous system is a crucial component in regulatory responses of the cardiovascular system. There has been increasing evidence of research demonstrating that dysregulation of this system has an important role in the pathogenesis of common cardiovascular disorders, including hypertension, heart failure, atrial fibrillation, cardiac sudden death or neurally-mediated syncope. This pa...

P2X receptors are ATP-gated cation channels that mediate fast excitatory transmission in diverse regions of the brain and spinal cord. Several P2X receptor subtypes, including P2X(7), have the unusual property of changing their ion selectivity during prolonged exposure to ATP, which results in a channel pore permeable to molecules as large as 900 daltons. The P2X(7) receptor was originally desc...

The important role of the vascular endothelium in cardiovascular health is increasingly recognized. However, mature endothelial cells possess limited regenerative capacity. There is therefore much interest in circulating endothelial progenitor cells (EPCs) among the scientific community, especially into their purported role in maintenance of endothelial integrity and function, as well as postna...

Case 1: A 45-year-old man in sinus rhythm, with an ejection fraction of 20%, normal coronaries, and normal renal function is receiving captopril 50 mg 3 times daily, carvedilol 25 mg and furosemide 40 mg twice daily, and spironolactone 25 mg daily. Despite these therapies, he continues to complain of dyspnea with minimal exertion. There are jugular venous distention, rales, and ankle edema. Ora...

A series of cardiovascular abnormalities may be associated with Turner’s Syndrome (TS). Over 50% of the reported cardiovascular malformations have been bicuspid aortic valve or coarctation of the aorta alone. or in a combination, which may lead to a higher risk for infective endocarditis. Isolated dilation of the ascending aorta was often seen in TS, while aortic dissection has been increasingl...

In this issue of Hypertension, Shibao et al 1 describe a series of tests that elucidate mast cell activation as a novel cause of postural orthostatic tachycardia syndrome (POTS) and orthostatic hypotension (OH). Because blood pressure control systems are redundant, patients with OH often have more than a single cause of their postural symptoms, and elucidating these causes can be challenging. T...

Compelling data demonstrate a strong association between sleep-disordered breathing (SDB) and cardiovascular disorders. The association is most consistent between obstructive sleep apnea (OSA) and hypertension. Epidemiologic and clinic-based studies provide evidence for an etiological role of OSA in hypertension, independent of obesity. Furthermore, several studies suggest amelioration of hyper...
