Outcomes of cryoballoon or radiofrequency ablation in symptomatic paroxysmal or persistent atrial fibrillation

AbstractAimsTo evaluate the effectiveness and safety of cryoballoon ablation (CBA) compared with radiofrequency ablation (RFA) for symptomatic paroxysmal or drug-refractory persistent atrial fibrillation (AF).Methods and resultsProspective cluster cohort study in experienced CBA and RFA centres. Primary endpoint was ‘atrial arrhythmia recurrence’, secondary endpoints were as follows: procedural results, safety, and clinical course. A total of 4189 patients were included: CBA 2329 (55.6%) and RFA 1860 (44.4%). Cryoballoon ablation population was younger, with fewer comorbidities. Procedure time was longer in the RFA group (P = 0.01). Radiation exposure was 2487 (CBA) and 1792 cGycm2 (RFA) (P

AbstractRanolazine is an anti-anginal medication that reduces the sodium-dependent calcium overload via the inhibition of the late sodium current. After its approval for the treatment of chronic angina in 2006 in the USA, ranolazine has been reported to have several pleiotropic effects on various cardiac conditions, such as atrial fibrillation, ventricular arrhythmias, diastolic and microvascular dysfunction, and pulmonary arterial hypertension. Recently, several studies reported some promising results on the potential benefits of ranolazine on glycemic control. Though the mechanism of the antihyperglycemic effect is still...

Researchers here argue that fibrosis of cardiac tissue is an important contribution to the development of atrial fibrillation in older patients. Fibrosis is a feature of many age-related conditions, a dysfunction in tissue maintenance processes that involves the generation of scar-like deposits of collagen by overactive fibroblasts. This scarring disrupts normal tissue structure and function in many organs, including the heart, and there is no good approved therapy to treat the progression of fibrosis: even slowing it is haphazard and unreliable. This may soon change. Fibrosis appears to be caused to a large degree ...

Discussion From Beth Israel Deaconess Medical Center. Ann Intern Med. 2019 Dec 03;171(11):828-836 Authors: Burns RB, Zimetbaum P, Lubitz SA, Smetana GW Abstract Atrial fibrillation (AFib) is the most common type of cardiac arrhythmia, affecting 2.7 million to 6.1 million persons in the United States. Although some persons with AFib have no symptoms, others do. For those without symptoms, AFib may be detected by 12-lead electrocardiogram (ECG), single-lead monitors (such as ambulatory blood pressure monitors and pulse oximeters), or consumer devices (such as wearable monitors and smartphones). Pulse pa...

In conclusion, T2D impairs vascular function by dysregulated autophagy. Therefore, autophagy could be a potential target for overcoming diabetic microvascular complications. To What Degree Does Loss of Skeletal Muscle with Age Contribute to Immunosenescence? https://www.fightaging.org/archives/2019/11/to-what-degree-does-loss-of-skeletal-muscle-with-age-contribute-to-immunosenescence/ Sarcopenia, the progressive loss of muscle mass and strength, is characteristic of aging. A perhaps surprisingly large fraction of the losses can be averted by strength training, but there are nonetheless inexorable process...

In this study, we sought to assess the prevalence of AF in patients with clinically undetected isolated cardiac amyloidosis (ICA) detected at autopsy and identify electrocardiographic (EKG) markers of such amyloid deposits. A total of 1083 patients were included in the study and 3.1% of patients were found to have asymptomatic ICA. Patients with ICA were older and had a higher odds of AF independent of age and CHA2DS2VASc score. Amongst patients with AF, those with ICA were more likely to have persistent forms of AF and had a lower sinus rhythm P-wave amplitude. Further studies are required to further define this entity, i...

ConclusionAblation lesion sequentiality measured by catheter inter-lesion distance and catheter stability measured by catheter excursion during lesion placement are potentially modifiable factors affecting arrhythmia recurrence after RF ablation for AF.

AbstractPurpose of ReviewThis review aims to explore the relationship between AF and carotid atherosclerosis, and the impact on the outcomes of cardiovascular and cerebrovascular events. Also, our aim is to critically review current knowledge and delineate future directions for effective treatment or prevention as well as strategies for improvement of the quality of life and survival.Recent FindingsAtrial fibrillation (AF) is the most common arrhythmia, increasing the risk of stroke and cardiovascular morbidity and mortality representing a significant worldwide public health problem. On the other hand, carotid artery ather...
