AI-Enhanced Cardiology Takes Another Step Forward
Combining a convolutional neural network with routine ECGs detected low ejection fraction, a signpost for Asymptomatic left ventricular systolic dysfunctionJohn Halamka, M.D., president, Mayo Clinic Platform, and Paul Cerrato, senior research analyst and communications specialist, Mayo Clinic Platform, wrote this article.Asymptomatic left ventricular systolic dysfunction (ALVSD) may not be the most familiar disorder in medicine, but it nonetheless increases a patient ’s risk of heart failure and death. Unfortunately, ALVSD is not that easily detected. Characterized by low ejection fraction (EF) — a measure of how much ...

Ebstein ’ s anomaly and pregnancy
Ebstein’s anomaly and pregnancy
Ebstein’s anomaly of tricuspid valve was first described by Wilhelm Ebstein in 1866 [1]. It is characterized by distal displacement of the septal and posterior leaflets of tricuspid valve. Anterior leaflet is elongated and sail like. A portion of the right ventricle is ‘atrialized’ due to the distal displacement of the tricuspid valve. Right atrium is often grossly dilated. Right to left shunting occurs across a patent foramen ovale producing cyanosis of variable extent. Ebstein’s anomaly is one of the cyanotic congenital heart diseases in which survival to adul...

Defining Hypertension : Why we remain in “ Status confusious ” despite 50 years of clinical trials ?
Next to the atmospheric pressure, the most curious pressure to understand is stored within human blood. Yes, it is the “blood pressure”, fondly referred to as BP by both physicians and patients. (When worried men & women visit us and say, that they are suffering from BP, please make it a point to clarify, BP is a sign of existence of life, rather than a dreaded pathology )
Why should blood have pressure?
BP is lateral pressure exerted by flowing blood on the vessel wall (or is it the propelling pressure head ? It is to be noted, cuff pressure doesn’t measure this !) BP is generated by the heart in...

Non-compaction of left ventricle
Non-compaction of left ventricle is often classified as a cardiomyopathy and is characterized by abnormal deep trabeculations, which is more at the apex [1]. Left ventricular non-compaction can be associated with left ventricular dilatation or hypertrophy. Systolic and diastolic dysfunction can occur and other congenital heart diseases can be associated. Ventricular arrhythmias and complete atrioventricular block can occur and present as syncope or sudden cardiac death.
Genetic transmission has been noted in 30-50% of patients and several genes have been implicated. NOTCH signaling pathway seems to be the final common pa...

Positron Emission Tomography (PET) in Cardiology
Positron emission tomography (PET) imaging is useful in assessment of myocardial perfusion and viability, atherosclerotic plaque activity as well as cardiac innervation in heart failure. PET is also useful in prosthetic valve endocarditis, endocarditis associated with cardiac implantable electronic devices (CIED), infiltrative cardiomyopathy, aortic stenosis and cardio oncology [1].
PET imaging has superior diagnostic accuracy compared to SPECT (Single Photon Emission Computed Tomography). It has improved spatial and temporal resolution and can measure regional blood flow and has less radiation. In PET, high energy gamma...

Coronary subclavian steal syndrome
Coronary subclavian steal syndrome is the diversion of blood from the coronary circulation to the exercising left upper limb after a coronary artery bypass graft (CABG) using left internal mammary artery [1]. This occurs when there is a high grade stenosis or occlusion of left subclavian artery proximal to the origin of the left internal mammary artery (LIMA). Though it is a rare phenomenon, it is a serious threat to the success of CABG.
Cardiovascular manifestation of coronary subclavian steal syndrome could be angina, myocardial infarction, malignant arrhythmias or heart failure [1]. Cerebral symptoms can occur due to ...

Acute aortic regurgitation
Clinical scenario of acute aortic regurgitation is quite different from familiar finding in chronic aortic regurgitation. Due to the atypical findings, it may be difficult to diagnose acute aortic regurgitation. All the same, it is not a stable condition like chronic aortic regurgitation. Acute regurgitation can rapidly progress to heart failure and early mortality if left untreated.
Important causes of acute aortic regurgitation are infective endocarditis, aortic dissection, and rarely trauma [1]. Rare causes reported are necrotizing granulomatous inflammation of the aortic valve in rheumatoid arthritis [2] and avulsion...

Fight Aging! Newsletter, April 12th 2021
In conclusion, the MR exhibited the protective effects against age-related behavioral disorders, which could be partly explained by activating circulating FGF21 and promoting mitochondrial biogenesis, and consequently suppressing the neuroinflammation and oxidative damages. These results demonstrate that FGF21 can be used as a potential nutritional factor in dietary restriction-based strategies for improving cognition associated with neurodegeneration disorders.

Takayasu arteritis
Takayasu arteritis is an inflammatory disorder affecting aorta and its major branches. It is also known as aortoarteritis and pulseless disease [1]. Arteritis leads to thickening of vessel wall, fibrosis, stenosis and thrombus formation. Severe inflammation may weaken the arterial media and lead to aneurysm formation [2].
Takayasu was an ophthalmologist, who noted characteristic fundal arteriovenous anastomoses in a young female in 1905 and published it in Acta of the Opthalmic Society of Japan in 1908 (12:554–5). Onishi and Kagosha described similar cases associated with absent radial pulses in the same year [1]. ...

CORAL study on renal artery stenting
In the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) study, 947 patients who had atherosclerotic renal artery stenosis and either systolic hypertension while taking two or more antihypertensive medications or chronic kidney disease were evaluated. It was a multi-center, open-label, randomized, controlled trial. Patients were randomized to either medical therapy plus renal artery stenting or medical therapy alone [1].
Previous randomized trials on renal angioplasty had failed to show significant benefit in control of blood pressure [2,3]. Another two randomized trials checking the effect of renal artery...

Measuring Gene Expression Changes in the Brain as a Result of Heart Failure
Heart failure causes harm to the brain by reducing the supply of blood, and thus the supply vital nutrients and oxygen, to brain cells. The precise details of how this leads to cognitive decline are yet to be fully mapped. Researchers here assess changes in gene expression the brains of mice suffering from heart failure, as a starting point for further investigation of specific mechanisms. The best path forward for this class of contribution to neurodegenerative conditions is to prevent or reverse vascular aging, which has numerous components. There is the narrowing of blood vessels via atherosclerosis; the failure of smoo...

Left ventricular remodeling
Left ventricular remodeling occurs in response to left ventricular stress and injury. It is progressive and occurs after large myocardial infarctions and dilated cardiomyopathy. Left ventricular volume increases and the normal elliptical shape becomes globular. Left ventricular remodeling is associated with changes at microscopic level which include myocyte hypertrophy, apoptosis and increased interstitial collagen deposition [1]. Left ventricular remodeling is a central pathophysiological mechanism in advancing heart failure. Reversal of remodeling with treatment is an important goal in the management of heart failure. ...

On the Value of Social Work in Palliative Care
by Vickie Leff (@VickieLeff)Another year, another study proving the value of the palliative care social worker. Edmonds et al (2021) found that when a social worker was involved in a palliative care consultation, whole-person care components were more likely to be addressed, including addressing psychological (82% vs 18%) and spiritual needs (92% vs 8%) and documenting advance directives (90% vs 10%). This adds to what we already knew: involvement of social work impacts quality of care and patient satisfaction (Auerbach, 2007; O ’Donnell et al., 2018).It surprises me that despite much research and team role development, ...

Returning to sports and physical activity after COVID-19: What parents need to know
While most children and teens who have COVID-19 recover completely, sometimes the virus can have lasting effects. One of those effects can be damage to the muscle of the heart — and if a damaged heart is stressed by exercise, it can lead to arrhythmias, heart failure, or even sudden death.
This appears to be rare. But given that we are literally learning as we go when it comes to COVID-19, it’s hard for us to know how rare — and just how risky exercise after testing positive for COVID-19 might be. To help doctors, coaches, gym teachers, parents, and caregivers make safe decisions, the American Academy of Pediatrics h...
