Studying the Clinical Data of COVID Positive patients admitted to a tertiary care academic hospital
Conclusion: The most common presenting symptoms included fever, cough, and shortness of breath. Patients who required ICU admission at presentation had a worse prognosis. Those with greater severity of symptoms were mainly elderly patients among which the most common comorbidity was hypertention followed by cardiac disease.

Impaired Activity of Ryanodine Receptors Contributes to Calcium Mishandling in Cardiomyocytes of Metabolic Syndrome Rats
Conclusion Principal findings of this work are that abnormal Ca2+ transient amplitude, contractile dysfunction; and impaired relaxation of MetS cardiomyocytes underlies intrinsic dysfunctional RyR2 and SERCA pump. Abnormal activity of RyRs was evidenced by its decreased ability to bind [3H]-ryanodine. Although the MetS condition does not modify RyR2 protein expression, its phosphorylation at Ser2814 is decreased, which impairs its capacity for activation during ECC. The dysfunctional RyRs, together with a decreased activity of SERCA pump due to decreased Thr17-PLN phosphorylation suggest a downregulation of CaMKII in MetS...

Age-Dependence of Flow Homeostasis in the Left Ventricle
Conclusions: In average, blood spends 1 to 3 beats inside the LV with very low shear stress rates. The apical region is the most prone to blood stasis, particularly in mid-aged adults. The washout of blood in the normal LV is age-dependent due to physiological changes in the degree of apical penetration of the filling waves. Introduction Cardioembolic stroke is a major source of mortality and disability worldwide and blood stasis one of its major determinants (Adams et al., 1986). Left ventricular (LV) function has evolved to maximize mechanical efficiency and ensure organ perfusion at a low cost of energy and fill...

Atrial Transcriptional Profiles of Molecular Targets Mediating Electrophysiological Function in Aging and Pgc-1 β Deficient Murine Hearts
Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health pro...

A Chinese Family With Adult-Onset Leigh-Like Syndrome Caused by the Heteroplasmic m.10191T > C Mutation in the Mitochondrial MTND3 Gene
Conclusion The m.10191T>C mutation in the mtDNA of the complex I (CI) subunit of MTND3 results in the substitution of a highly conserved amino acid (p.Ser45Pro) within the ND3 protein, leading to CI dysfunction through impaired enzyme catalysis rather than impaired stability or assembly, causing a broad clinical spectrum of disorders (26). Patients with the m.10191T>C mutation are rare. In the present study, we report on a family of patients with the extremely rare adult-onset Leigh-like syndrome with the m.10191T>C mutation. Including the two patients from our reported family, the m.10191T...

Nrf2 as a Potential Mediator of Cardiovascular Risk in Metabolic Diseases
Conclusion Activation of the Nrf2-dependent antioxidant system plays an important role in cell defense against oxidative stress damage, whereas the insufficiency of the Nrf2 system is associated with multiple aspects of the genesis and progression of metabolic diseases, posing a great risk to the cardiovascular system (Figure 1). The systemic increase of Nrf2 activity by several activators may be beneficial in the treatment of metabolic diseases. In addition, selective upregulation of Nrf2 genes may represent a potential therapy in obesity, diabetes and atherosclerosis. Looking to the future, experimental research that el...

YiQiFuMai Powder Injection Attenuates Coronary Artery Ligation-Induced Heart Failure Through Improving Mitochondrial Function via Regulating ROS Generation and CaMKII Signaling Pathways
This study was carried out in accordance with the recommendations of “Guide for the Care and Use of Laboratory Animals, National Institutes of Health.” The protocol was approved by the “China Pharmaceutical University.” Surgical Preparation The mice were anesthetized with chloral hydrate (4% chloral hydrate, ip). The HF model was induced by CAL as previously reported (Gao et al., 2010). Successful ligation of the coronary artery was confirmed by the occurrence of ST-segment elevation in electrocardiogram. Sham operated mice were performed the same process except left CAL. After ligation, the h...

WHO/ILO work-related burden of disease and injury: Protocol for systematic reviews of exposure to occupational noise and of the effect of exposure to occupational noise on cardiovascular disease.
aga JU Abstract BACKGROUND: The World Health Organization (WHO) and the International Labour Organization (ILO) are developing a joint methodology for estimating the national and global work-related burden of disease and injury (WHO/ILO joint methodology), with contributions from a large network of experts. In this paper, we present the protocol for two systematic reviews of parameters for estimating the number of deaths and disability-adjusted life years from cardiovascular disease attributable to exposure to occupational noise, to inform the development of the WHO/ILO joint methodology. OBJECTIVES: We aim t...

Pretransplant and perioperative predictors of early heart transplantation outcomes.
Conclusion. Pretransplant predictors of adverse outcome after heart transplantation were recipient age, lower BMI, ischemic cardiomyopathy, reoperation and diabetes. Postoperative predictors of mortality were inferior donor heart hemodynamics, epinephrine use, and serum lactate concentrations. Non-survivors were more likely to require re-sternotomy, MCS, and RRT.

The Case Files: When a Spade is Not a Spade
Turrin, Danielle DO; Sattler, Steven DO; Amodeo, Dana DO A 25-year-old Hispanic man presented to the emergency department with a complaint of three days of left-sided precordial chest pain. He described the pain as a constant 6/10 with pressure-like discomfort radiating to his left arm and the left side of his neck. He also experienced nausea, but denied any provocative or palliative factors. He said he had not experienced anything similar to this before. He had no family history of heart disease, acute myocardial infarction, or sudden cardiac death. He admitted to a 1.5 pack-per-day smoking history and social alcohol use,...

Freedom in waiting: A ventricular assist device gives Aidan’s family independence
Aidan When Aidan was just 8 months old, his parents Patrick and Tavina received shocking news—their son had hypertrophic cardiomyopathy, a rare but serious disease that affects the muscle of the heart. Given his young age and severity of his condition, the early prognosis was bleak. “Things didn’t look good at first,” remembers Patrick. “We were steeling ourselves for the real possibility that Aidan wouldn’t make it to see his first birthday.” But, heart condition or not, little Aidan was a fighter, and with minimal medical management his condition stabilized. Over the years, he grew ...
