Autophagy in the Diabetic Heart: A Potential Pharmacotherapeutic Target in Diabetic Cardiomyopathy.

Ageing Res Rev 2021 Apr 7:101338. Epub 2021 Apr 7.

Department of Biochemistry, Kakatiya Medical College, Warangal, 506007, Telangana, India; Applied Biology, CSIR-Indian Institute of Technology, Uppal Road, Tarnaka, Hyderabad, 50000, Telangana, India. Electronic address:

Association of diabetes with an elevated risk of cardiac failure has been clinically evident. Diabetes potentiates diastolic and systolic cardiac failure following the myocardial infarction that produces the cardiac muscle-specific microvascular complication, clinically termed as diabetic cardiomyopathy. Elevated susceptibility of diabetic cardiomyopathy is primarily caused by the generation of free radicals in the hyperglycemic milieu, compromising the myocardial contractility and normal cardiac functions with increasing redox insult, impaired mitochondria, damaged organelles, apoptosis, and cardiomyocytes fibrosis.

Iron deficiency is associated with impaired biventricular reserve and reduced exercise capacity in patients with unexplained dyspnea.

J Card Fail 2021 Apr 7. Epub 2021 Apr 7.

Department of Cardiology, Hartcentrum, Jessa Hospital, Hasselt, Belgium; Faculty of Medicine and Life Sciences, Hasselt University, Hasselt, Belgium.

Background: Iron deficiency (ID) is frequent and associated with diminished exercise capacity in heart failure (HF), but its contribution to unexplained dyspnea without a HF diagnosis at rest remains unclear.

Methods: Consecutive patients with unexplained dyspnea and normal echocardiography and pulmonary function tests at rest underwent prospective standardized cardiopulmonary exercise testing with echocardiography (CPETecho) in a tertiary care dyspnea clinic. ID was defined as ferritin <300µg/l and transferrin saturation (TSAT)<20% and its impact on peak oxygen uptake (peakVO), biventricular response to exercise, and peripheral oxygen extraction was assessed.

Inferior mesenteric arteriovenous fistula with colonic ischemia: a case report and review of the literature.

Clin J Gastroenterol 2021 Apr 10. Epub 2021 Apr 10.

Department of Radiology, Saint-Eloi University Hospital, 80 Av. Augustin Fliche, 34000, Montpellier, France.

Inferior mesenteric arteriovenous fistula is a rare abnormal high flow communication with only 40 primary and secondary cases reported in literature. Shunting of arterial flow through the inferior mesenteric vein to the portal system can cause a variety of nonspecific clinical signs and symptoms usually associated with the diagnosis of arteriovenous malformation. Symptom intensities are flow-dependent and can range from minimal abdominal symptoms to severe heart failure due to left to right shunt. Read More

The bidirectional interaction between atrial fibrillation and heart failure: consequences for the management of both diseases.

Europace 2021 Apr;23(Supplement_2):ii40-ii45

Department of Cardiology, Cardiovascular Research Institute Maastricht (CARIM), Maastricht University Medical Center (MUMC+), Maastricht, The Netherlands.

Atrial fibrillation (AF) and heart failure (HF) are both highly prevalent diseases and are accompanied by a significant disease burden and increased mortality. Although the conditions may exist independently, they often go hand in hand as each is able to provoke, sustain, and aggravate the other. In addition, the diseases share a risk profile with several coinciding cardiovascular risk factors, promoting the odds of developing both AF and HF separately from each other. Read More

Association between Heart Failure and Clinical Prognosis in Patients with Acute Ischemic Stroke: A Retrospective Cohort Study.

J Clin Neurol 2021 Apr;17(2):200-205

School of Medicine, Universidad de la Sabana, Chía, Colombia.

Background And Purpose: Ischemic stroke is a common cause of death worldwide. In clinical practice it is observed that many individuals who have experienced an ischemic stroke also suffer from simultaneous comorbidities such as heart failure, which could be directly associated with a worse clinical prognosis. Therefore, this study analyzed outcomes in terms of the severity of the event, inhospital mortality, duration of hospital stay, and inhospital recurrence of the episode, in order to determine the implications resulting from the presentation of both pathologies.
