Novel Echocardiographic Biomarkers in the Management of Atrial Fibrillation

AbstractPurpose of ReviewAtrial fibrillation (AF) is the most common arrhythmia in adults. The number of patients with AF is anticipated to increase annually, mainly due to the aging population alongside improved arrhythmia detection. AF is associated with a significantly elevated risk of hospitalization, stroke, thromboembolism, heart failure, and all-cause mortality. Echocardiography is one of the key components of routine assessment and management of AF. Therefore, the aim of this review is to briefly summarize current knowledge on “novel” echocardiographic parameters that may be of value in the management of AF patients.Recent FindingsNovel echocardiographic biomarkers and their clinical application related to the management of AF have been taken into consideration. Both standard parameters such as atrial size and volume but also novels like atrial strain and tissue Doppler techniques have been analyzed.SummaryA number of novel echocardiographic parameters have been proven to enable early detection of left atrial dysfunction along with increased diagnosis accuracy. This concerns particularly experienced echocardiographers. Hence, these techniques might improve the prediction of stroke and thromboembolic events among AF patients and need to be further developed and disseminated. Nonetheless, even the standard imaging parameters could be of significant value and should not be discontinued in everyday clinical practice.

ConclusionTTS has a good short- and medium-term prognosis. However, the rate of in-hospital complications is high and should not be overlooked. Dyspnea at presentation, CKD, CAD and lower LVEF on admission were independent predictors of in-hospital complications. Prolonged QTc on admission was associated with complications in follow-up.ResumoIntroduçãoA síndrome de Takotsubo (TTS) caracteriza-se por disfunção sistólica ventricular esquerda transitória.ObjetivoCaracterizar uma população portuguesa com TTS e determinar o seu prognóstico a curto e mé...

Conclusion An occult preexisting atrial fibrillation may lead to unnecessary percutaneous foramen ovale closure in a significant proportion of patients. A 6-month loop-recorder monitoring may improve the patient oriented decision-making.

Atrial fibrillation (AF) is the most common arrhythmia and is associated with increased morbidity and mortality, with heart failure (HF) and thromboembolism including stroke being the major consequences.1 Thus, stroke prevention with oral anticoagulants is crucial, but highly challenging, for AF management in many patients.2,3 Although our understanding of the underlying molecular mechanisms promoting AF increased substantially over the years, contemporary approaches using drugs are only moderately effective and have substantial side effects, including proarrhythmia.

Commonest sustained arrhythmia in hypertrophic cardiomyopathy: Correct answer: d) Atrial fibrillation Atrial fibrillation (AF) can occur in about 1/5th of cases of hypertrophic cardiomyopathy (HCM). Factors predisposing to AF in HCM are left atrial pressure and size due to left ventricular diastolic dysfunction, left ventricular outflow tract obstruction and mitral regurgitation. About one fourth of them may develop embolic episodes and stroke. It has been suggested that those with left atrial diameter of 45 mm or more should undergo 48 hour Holter once or twice a year to look for AF. Anticoagulation is recommended in tho...

Atrial fibrillation (AF) is a common arrhythmia associated with debilitating consequences such as stroke, heart failure and venous thromboembolism. In HK, 20-25% of stroke cases are related to AF leading to a significant burden. Warfarin has been the frontline oral anticoagulant for AF but with high bleeding risk and hence monitoring and dose adjustment are required. The non-vitamin-K antagonist oral anticoagulants (NOACs) are alternatives to warfarin for preventing stroke and systemic embolism in non-valvular AF (NVAF) patients.

Authors: Batul SA, Gopinathannair R Abstract Atrial fibrillation (AF) and heart failure (HF) are growing cardiovascular disease epidemics worldwide. There has been an exponential increase in the prevalence of AF and HF correlating with an increased burden of cardiac risk factors and improved survival rates in patients with structural heart disease. AF is associated with adverse prognostic outcomes in HF and is most evident in mild-to-moderate left ventricular (LV) dysfunction where the loss of "atrial kick" translates into poorer quality of life and increased mortality. In the absence of underlying struct...

Abstract Background -Atrial fibrillation (AF), the most common sustained arrhythmia in hypertrophic cardiomyopathy (HCM), is capable of producing symptoms that impact quality of life and is associated with risk for embolic stroke. However, the influence of AF on clinical course and outcome in HCM remains incompletely resolved. Methods -Records were accessed of 1558 consecutive patients followed at the Tufts Medical Center Hypertrophic Cardiomyopathy Institute for 4.8 ± 3.4 years, from 2004 to 2014. Results -Of the 1558 HCM patients, 304 (20%) had episodes of AF, of which 226 (74%) were confined to symptomat...

Conclusion Calculation of the CHADS2 and mCHA2DS2-VASc scores in order to evaluate the risk of systemic thromboembolism was useful to predict the onset of CHF, but not all-cause death, in patients with NVAF.

Background and Purpose—The CHA2DS2-VASc stroke score (congestive heart failure, hypertension, age ≥75 (doubled), diabetes mellitus, prior stroke or transient ischemic attack (doubled), vascular disease, age 65–74, female) is used in most guidelines for risk stratification in atrial fibrillation (AF), but most data for this score have been derived in Western populations. Ethnic differences in stroke risk may be present. Our objective was to investigate risk factors for stroke in AF and application of the CHA2DS2-VASc score in an Asian AF population from Korea.Methods—A total of 5855 oral anticoagulant&n...
