Equal heartbeat intervals and their effects on the nonlinearity of permutation-based time irreversibility in heart rate

Publication date: Available online 7 March 2019Source: Physics Letters AAuthor(s): Wenpo Yao, Wenli Yao, Jun WangAbstractThe association of equal heartbeat intervals with cardiac conditions and the effect of the equality on permutation-based time irreversibility are investigated in this paper. We measure the distributions of equal heartbeat intervals under three conditions, namely congestive heart failure (CHF), healthy young and elderly, whose time irreversibility is detected by measuring the probabilistic difference between permutations instead of raw vectors. We demonstrate that heartbeats contain high rates of equal states, particularly the CHF with around 20% equalities, and the distributions of equal values discriminate the heartbeats at very short data length. The CHF have more equal values than the healthy young (p

Clinicians lack reliable methods to predict which patients with congestive heart failure (CHF) will benefit from cardiac resynchronization therapy (CRT). Symptom burden possibly predicts response, but this information is buried in free-text clinical notes. Artificial intelligence (AI) tools to identify symptoms in the electronic health record (EHR) may allow for the structured inclusion of these data into pre-procedural decision-making.

ConclusionsOur study analyzed the relationship of frailty and postoperative complications in patients with long bone fractures. Patients had increased likelihood of morbidity, independent of other comorbidities and demographic factors. The mFI may have a role as a simple, easy to use risk assessment tool in cases of orthopedic trauma.

Mechanical  circulatory support (MCS) evolved from an engineering dream to clinical reality during the 1980s when increasing numbers of patients were dying on heart transplant wait lists. Following the Randomized Evaluation of Mechanical Assistance for the Treatment of Congestive Heart Failure Trial,1 the US Food and Drug Administration (FDA) approved a pulsatile implantable left ventricular assist device (LVAD) for long-term implantation in 2002. When the FDA approved the first US continuous flow (CF) LVAD in 2008, the landscape had changed dramatically.

Early-stage CAD can progress if undiagnosed and left untreated, leading to myocardial infarction (MI) that may induce irreversible heart muscle damage, resulting in heart chamber remodeling and eventual congestive heart failure (CHF). Electrocardiog...

Abstract Fluid management with diuretics is a key factor for postoperative management following cardiovascular surgery, and it is common to administer intermittent doses of diuretics and fluids in the early postoperative stage as primary therapy. Loop diuretics are usually given as the first option, followed by an aldosterone blocker, mannitol, and human atrial natriuretic peptide (hANP) or recombinant human B-type natriuretic peptide infusion. Although the effects of tolvaptan, a new type of diuretic with an aquaretic effect to increase urine volume without increasing electrolyte excretion into urine by blocking ...

AbstractCardiovascular diseases, including hypertension, congestive heart failure, myocardial infarction, stroke and atherosclerosis, are common in patients with chronic kidney disease. Aside from the standard biomarkers, measured to determine cardiovascular risk, new ones have emerged: markers of oxidative stress, apoptosis, inflammation, vascular endothelium dysfunction, atherosclerosis, organ calcification and fibrosis. Unfortunately, their utility for routine clinical application remains to be elucidated. A causal relationship between new markers and cardiovascular diseases in patients with chronic kidney disease remai...
