Patients with mitral annular disjunction present with frequent premature ventricular contractions; in this study, one-third had ventricular arrhythmias & one-tenth had severe arrhythmic events. @JACCJournals onlinejacc.org/content/72/14/…
A total of 82 (71%) patients reported #palpitations, 47 (41%) patients reported previous pre-syncope, 40 (34%) had ventricular arrhythmia, 15 (13%) had experienced #syncope, & 14 (12%) patients had experienced a severe arrhythmic event prior to inclusion
Mitral valve prolapse was present in 90 (78%) patients
Young age, lower ejection fraction, & papillary muscle fibrosis were identified as markers for severe arrhythmic events.
Longitudinal mitral annular disjunction distance in the posterolateral wall & papillary muscle fibrosis assessed by #CMR remained markers of ventricular arrhythmia in multivariate analysis.
Physicians should consider mitral annular disjunction in younger patients with no other apparent cause for premature ventricular contractions & refer these patients to an #echocardiographic study.
Mitral annular disjunction is readily detectable by #echocardiography, with the typical curling motion of the left ventricular basal posterolateral wall.
In patients with incidental findings of mitral annular disjunction, a careful history of #palpitations, #syncope, & 24-h #ECG recording may be appropriate.
Furthermore, physicians should be attentive to possible mitral annular disjunction in patients followed for mitral value prolapse & mitral regurgitation.
#CMR may add to risk stratification by detecting papillary muscle fibrosis & measuring longitudinal mitral annular disjunction distance in the posterolateral wall. @JACCJournals onlinejacc.org/content/72/14/…

This nationwide complete analysis of all adult deaths in #England & #Wales has found that the #COVID pandemic has resulted in an abrupt inflation in acute #cardiovascular deaths above that expected for the time of year. heart.bmj.com/content/early/…
That is, about 2000 additional deaths over a 4 month period.
Nearly half of the deaths occurred outside of the #hospital setting, either at #home or in #carehomes.

Emerging data from @PHE_uk suggests a synergistic detrimental effect of co-infection with #SARS_CoV_2 & #flu viruses. The preprint (not peer reviewed) article is available here medrxiv.org/content/10.110…
‘The risk of testing positive for #SARS_CoV_2 was 68% lower among #influenza positive cases, suggesting possible pathogenic competition between the two viruses.’
However, ‘Patients with a coinfection had a risk of death of 5.92 (95% CI, 3.21-10.91) times greater than among those with neither influenza nor SARS-CoV-2 suggesting possible synergistic effects in coinfected individuals.’

Advances in #cancer treatment have improved clinical outcomes, leading to an increasing population of cancer survivors. Yet, this success is associated with high rates of short‐ & long‐term #cardiovascular toxicities. The Cancer Patient and Cardiology onlinelibrary.wiley.com/doi/abs/10.100…
The number & variety of #cancer drugs & #cardiovascular toxicity types make long‐term care a complex undertaking.
This requires a multidisciplinary approach including expertise from #oncology, #cardiology, & other related specialties, & has led to the development of the cardio‐oncology subspecialty.

This cluster randomised controlled trial found that opportunistic screening in primary care did not increase the detection of #AFib compared with usual care in patients aged 65 & over @bmj_latest bmj.com/content/370/bm…

Yet the findings are in contrast to the SAFE study which showed that opportunistic screening for #atrialfibrillation over a year detected more new diagnoses than usual care.
