Bone marrow-derived naïve B lymphocytes improve heart function after myocardial infarction: a novel cardioprotective mechanism for empagliflozin - Basic Research in Cardiology

Bone marrow-derived naïve B lymphocytes improve heart function after myocardial infarction: a novel cardioprotective mechanism for empagliflozin - Basic Research in Cardiology

Source : https://link.springer.com/article/10.1007/s00395-022-00956-1

The role of adaptive immunity in myocardial recovery post myocardial infarction (MI), particularly the immune response by B lymphocytes, remains elusive. Bone marrow immune microenvironment in response to MI is...


Conclusions: These findings provide new mechanistic insights into regulation of adaptive immune response post MI, and support targeting bone marrow B cell development for improved ventricular remodeling and reduced heart failure after MI.

Transvenous Right Greater Splanchnic Nerve Ablation in Heart Failure and Preserved Ejection Fraction: First-in-Human Study

Transvenous Right Greater Splanchnic Nerve Ablation in Heart Failure and Preserved Ejection Fraction: First-in-Human Study

Source : https://www.sciencedirect.com/science/article/pii/S221317792200316X?via=ihub

Ablation of the right-sided greater splanchnic nerve (GSN) can reduce excessive splanchnic vasoconstriction, potentially improving the handling of volume shifts in patients with heart failure with preserved ejection fraction (HFpEF)....


Conclusions: In this open-label, single-arm feasibility study, right-sided GSN ablation was safe and improved mostly subjective clinical metrics in patients with HFpEF over 12 months.

Periodontal Status, C-Reactive Protein, NT-proBNP, and Incident Heart Failure: The ARIC Study

Periodontal Status, C-Reactive Protein, NT-proBNP, and Incident Heart Failure: The ARIC Study

Source : https://www.sciencedirect.com/science/article/abs/pii/S2213177922003146?via=ihub

Periodontal disease (PD), resulting from inflammatory host response to dysbiotic subgingival microbiota, has been linked to cardiovascular disease; however, its relationship to heart failure (HF) and its subtypes (heart failure...


Conclusions: Periodontal status was associated with incident HF, HFpEF, and HFrEF, as well as unfavorable changes in CRP and NT-proBNP.

Defining the Phenotypes for Heart Failure With Preserved Ejection Fraction - Current Heart Failure Reports

Defining the Phenotypes for Heart Failure With Preserved Ejection Fraction - Current Heart Failure Reports

Source : https://link.springer.com/article/10.1007/s11897-022-00582-x

Purpose of Review Heart failure with preserved ejection fraction (HFpEF) imposes a significant burden on society and healthcare. The lack in efficacious therapies is likely due to the significant heterogeneity...


Summary: We synthesized the literature and propose three broad phenotypes: (1) young, with few comorbidities, usually obese and with low natriuretic peptide levels, (2) obese with substantive cardiometabolic burden and comorbidities and impaired ventricular relaxation, (3) old, multimorbid, with high rates of atrial fibrillation, renal and...

Case 1: A 68-year-old female patient presents with fatigue, chest pain, palpitations, dyspnea, and syncope while performing normal physical activity. She is comfortable at rest, with limited impairment of functional status. She is categorized as having HFpEF NYHA Class II, with an LVEF of 58% and an eGFR of 61 mL/min/1.73 m2. She is currently taking ACE inhibitors and diuretics.

Case 2: A 65-year-old man is experiencing symptoms fatigue, chest pain, palpitations, dyspnea, and syncope with less than normal physical activity. He is comfortable at rest only, with limitations on functional status. He recently transitioned to HFpEF NYHA Class III, with an LVEF of 35% and eGFR of 58 mL/min/1.73 m2. He is currently taking an ARB, diuretic, and beta blocker.

In both patients, the addition of which agent would result in a relative risk reduction in time to cardiovascular death or hospitalization due to heart failure? Before prescribing this drug, in which patients should renal function and volume status be tested? What are the most common adverse reactions for this drug (i.e., occurring in ≥5% of patients)?

    Jardiance can be helpful in both patients. I would assure creatinine clearance is above 25 cc/min before prescribing SGLT2 inhibitor like Jardiance. Volume status should be assessed clinically from physical Show More

    I would start with adding spironolactone and empaliflozin in patient 1 and recheck renal function and electrolytes in 1-2 weeks. In patient 2, I would change ARB to Entresto and Show More
