The lifetime risk of developing atrial fibrillation (AF) is 1 in 3 adults, resulting in a prevalence of 2-4%. Rheumatic heart disease (RHD) is a frequent aetiology of valvular heart disease in lowand middle-income countries. Between 21% and 80% of patients with mitral valve disease, especially with stenosis, may have AF.

- Intradialytic blood pressure (BP) is primarily used to monitor patients during hemodialysis (HD), but knowing details about cardiac output and resistance could offer better insights.
- A study employed a non-invasive bio-impedance system to assess multiple hemodynamic parameters in chronic HD patients, examining changes before, during, and after dialysis across various hemodynamic profiles.
- The findings indicated that most patients did not remain hemodynamically stable during dialysis, with higher mortality rates observed in those with low cardiac power and total peripheral resistance, suggesting that enhanced monitoring could improve patient safety during HD treatments.
Background: Intradialytic hypotension is a clinically significant problem, however, the hemodynamics that underlie ultrafiltration and consequent hypotensive episodes has not been studied comprehensively.
Methods: Intradialytic cardiac output, cardiac power and peripheral resistance changes from pretreatment measurements were evaluated using a novel regional impedance cardiographic device (NICaS, NI Medical, Peta Tikva, Israel) in 263 hemodialysis sessions in 54 patients in dialysis units in the USA and Brazil with the goal of determining the various hemodynamic trends as blood pressure decreases.
Results: Hypotensive episodes occurred in 99 (13.
