Role of Iron Therapy in Heart Failure: A Consensus Statement from India.

Iron deficiency (ID) with or without anemia is frequently observed in patients with heart failure (HF). Uncorrected ID is associated with higher hospitalization and mortality in patients with acute HF (AHF) and chronic HF (CHF). Hence, in addition to chronic renal insufficiency, anemia, and diabetes, ID appears as a novel comorbidity and a treatment target of CHF. Intravenous (IV) ferric carboxymaltose (FCM) reduces the hospitalization risk due to HF worsening and improves functional capacity and quality of life (QOL) in HF patients. The current consensus document provides criteria, an expert opinion on the diagnosis of ID in HF, patient profiles for IV FCM, and correct administration and monitoring of such patients.

Angiotensin Receptor-Neprilysin Inhibitor Therapy and Cardiac Remodeling in Heart Failure: Consensus Statement from India.

Adverse cardiac remodeling refers to progressive structural and functional modifications in the heart because of increased wall stress in the myocardium, loss of viable myocardium, and neurohormonal stimulation. The guideline-directed medical therapy for Heart failure (HF) includes Angiotensin receptor-neprilysin inhibitor (ARNI) (sacubitril/valsartan), ß-blockers, sodium-glucose co-transporter 2 (SGLT2) inhibitors, and mineralocorticoid receptor antagonists (MRA). ARNI is under-prescribed in India despite its attractive safety and efficacy profile. Therefore, the consensus discusses objectives and topics related to ARNI in the management of cardiac remodeling, and experts shared their views on the early timely intervention of effective dosage of ARNI to improve the diagnosis and enhance mortality and morbidity benefits in cardiac reverse remodeling (CRR).

Noninvasive Measurement of Aortic Pressure and Evaluation of Arterial Stiffness in Patients with Hypertension: An Observational Study.

AIM: Arterial stiffness, a major marker of vascular impedance, has been identified as a predictor of adverse cardiac outcomes. The present study determined the relationship between blood pressure (BP) and arterial stiffness measured noninvasively using a periscope in hypertensive patients. It has also evaluated the usefulness of indices of arterial stiffness in cardiovascular (CV) risk stratification and the necessity to implement these aortic pressure parameters in clinical practice. METHODS: The prospective, observational study involved patients with hypertension between the age of 18 and 80 years. The demographic and anthropometric measurements of all the participants were recorded and various central and peripheral (brachial) arterial pressure parameters were measured using a periscope. The clinical variables were compared separately for different CV risk grades and arterial stiffness index (ASI) using Kruskal-Wallis test for non-normal data and chi-square test for count data. The correlation of different parameters with CV risk grade and ASI were evaluated using Spearmen's correlation method. The agreement of different ASI indices with CV risk grades was assessed using Kappa method. RESULTS: The study recruited a total of 3,032 patients with hypertension. Classification of the subjects for CV risk grades had demonstrated that major proportion of the patients (n = 713) had moderate and severe CV risks (n = 708). The classification of hypertensive patients for arterial stiffness had shown that 1,037 subjects had severe arterial stiffness. Classification of arterial stiffness based on BP levels had demonstrated that 623 patients with severe arterial stiffness and 315 with borderline arterial stiffness had stage II hypertension, and 480 patients with normal BP had no arterial stiffness. Brachial ASI had a strong correlation with systolic BP (SBP). A very good agreement with K value 0.871 was noted for Kappa agreement of arterial stiffness indices with CV risk. CONCLUSION: The present study corroborates the use of central BP parameters as indicators of arterial stiffness in hypertensive subjects. Noninvasive measurement of these indices has wider implications in personalized risk assessment of CV risk in subjects with hypertension.

Evaluation of Effectiveness and Tolerability of Fondaparinux in the Management of Symptomatic Acute Coronary Syndrome: A Real-World Evidence-Based Study on an Indian Population.

INTRODUCTION: Fondaparinux is a low molecular weight heparin anticoagulant used to manage the full spectrum of acute coronary syndrome (ACS) patients and has proved its efficacy and safety in multiple clinical trials. However, there are limited data available showing whether the same results could be reproduced in real-world practice on an Indian population. Our objective was to determine the effectiveness and tolerability of fondaparinux in the management of symptomatic ACS in real-world clinical practice. METHODS: The EMR data of hospitalized ACS patients (n = 611), from January 2015 to January 2020, representing UA or NSTEMI or STEMI and were prescribed fondaparinux (2.5 mg once daily) to manage ACS were analyzed. The effectiveness was analyzed as recurrence of ACS and tolerability as total incidence of major bleeding during hospitalization, at 30 days and 180 days. Appropriate statistical analysis was used with a statistically significance of p value < 0.05. RESULTS: The incidence of recurrent ACS was not seen during hospitalization and in the first 30 days, while in only 0.65% (n = 4) patients, ACS reoccurred within 180 days. In a mean duration of 172.75 ± 3.20 days, UA was reported in 0.49% (n = 3) patients, NSTEMI in 0.16% (n = 1) of patients, and STEMI was not documented. None of the major bleeding events occurred during the entire study period, whereas minor bleeding events were reported during hospitalization 0.98% (n = 6) and at 30 days 0.16% (n = 1). The bleeding events were statistically insignificant (p value > 0.05). No incidences of stent thrombosis were reported during the entire study period. CONCLUSIONS: In the real world, fondaparinux was found to be effective and tolerable when used to manage symptomatic ACS patients regardless of revascularization procedure with no incidence of stent thrombosis, and minimal recurrent ACS and insignificant increase in bleeding events.

Therapeutic adherence in hypertension: Current evidence and expert opinion from India.

Hypertension (HTN) is a globally prevalent non-communicable disease contributing significantly to cardiovascular (CV) morbidity and mortality. In achieving control of HTN, therapeutic adherence plays a crucial role. Studies from India identify varying rates of adherence to antihypertensive medications. Multiple factors determine treatment adherence in HTN. In India, factors such as lower socioeconomic status, health literacy, asymptomatic nature of disease, forgetfulness, cost of medications, and duration of HTN determine the adherence. An excellent physician-patient relationship incorporating adequate counseling along with the use of other methods can identify poor adherence. Improving adherence necessitates incorporating a multipronged approach with strategies directed at physicians, patients, and health systems. With innovation in therapeutics, the pharmaceutical sector can contribute significantly to improve adherence. Furthermore, increasing adherence to lifestyle interventions can help achieve better HTN control and improve CV outcomes. In the Indian context, more emphasis is necessary on patient education, enhanced physician-patient relationship and communication, increased access to health care, and affordability in improving therapeutic adherence in HTN.

Expert Opinion on P2Y12 Inhibitors Use in Management of Acute Coronary Syndromes: Focus on Ticagrelor.

Ticagrelor is a potent, oral P2Y12 inhibitor used as a part of dual antiplatelet therapy (DAPT) in acute coronary syndromes (ACS). New evidence has emerged for its use in ACS, which may be crucial for the Indian context. This brought together nearly 150 experts in ACS management across the country who reviewed the current evidence and discussed the same through a series of 10 meetings on an online platform. With all experts' agreement, the key expert opinions for the P2Y12 inhibitors use in ACS management were finalized. These include the following. In ACS patients aged <75 years, with diabetes, a history of stroke/transient ischemic attack, and chronic kidney disease, ticagrelor may be preferred over other P2Y12 inhibitors. It may also be preferred in the elderly above 75 years with clopidogrel is a suitable alternative in patients at high-risk of bleeding. Rates of stent thrombosis are lower with ticagrelor than clopidogrel. In patients managed with fibrinolysis, use ticagrelor after 48 hours if streptokinase was the fibrinolytic agent or it can be used after 12 to 24 hours if fibrin-specific fibrinolytic was used. Rates of major bleeding in patients treated with fibrinolysis are similar to clopidogrel. Prehospital administration may be preferred over in-hospital administration with expected bleeding rates similar to clopidogrel. Switching among P2Y12 inhibitors should be done with due consideration of their pharmacodynamics. At present, DAPT should be continued for 12 months with discontinuation after three to six months in patients with high bleeding risk. The use of low dose ticagrelor may be considered in cases with high-bleeding risk. DAPT or ticagrelor continuation beyond one year should be individualized considering ischemic and bleeding risks. Dyspnea is a common, mild, and transient and does not necessitate ticagrelor discontinuation. Severe dyspnea should be investigated thoroughly. In conclusion, ticagrelor (180 mg, 90 mg, and 60 mg doses), a potent antiplatelet is expected to reshape the antiplatelet use in the management of ACS.

Last ditch CRT: right is not always wrong!

Cardiac resynchronization therapy (CRT) has become the mainstay of refractory heart failure treatment. Usually the patients having right bundle branch block (RBBB) on electrocardiogram are considered as relative contraindication as there is no or minimal dyssynchrony in them. We present a case where CRT was put in as last resort in a patient with RBBB and was successful. Short literature review is done on the CRT implantation in patients with RBBB.

Successful RF ablation of atrial tachycardia from the non-coronary aortic cusp.

A 51-year-old lady presented with recurrent episodes of supraventricular tachycardia since 1 year. EP study revealed easily inducible atrial tachycardia. Endocardially, the earliest activation site was found in the His bundle region (-18 ms). The aorta was therefore mapped, and a site in the non-coronary cusp was found with an activation time of -30 ms. RF energy at this site successfully eliminated tachycardia. She is asymptomatic at 8 months of follow-up, without any anti-arrhythmic drug.

Occurrence of "J waves" in 12-lead ECG as a marker of acute ischemia and their cellular basis.

The "J wave" (also referred to as "the Osborn wave,""the J deflection," or "the camel's hump") is a distinctive deflection occurring at the QRS-ST junction. In 1953, Dr. John Osborn described the "J wave" as an "injury current" resulting in ventricular fibrillation during experimental hypothermia. Although "J Wave" is supposed to be pathognomonic of hypothermia, it is seen in a host of other conditions such as hypercalcemia, brain injury, subarachnoid hemorrhage, cardiopulmonary arrest from over sedation, the Brugada syndrome, vasospastic angina, and idiopathic ventricular fibrillation. However, there is paucity of literature data as regards to ischemic etiology of "J Wave." In this article, we present a case where "J waves" were probably induced by ischemia. We also discuss the mechanism of ischemia-induced "J wave" accentuation and its prognostic implications.

Transjugular approach to balloon mitral valvuloplasty helps overcome impediments caused by anatomical alterations.

Ten patients who had anatomic alterations that cause impediments to successful completion of conventional transfemoral balloon mitral valvuloplasty (BMV) underwent transjugular BMV. They included six patients in whom conventional BMV could not be completed due to cardiac anatomic distortion; two patients with dextrocardia (one with visceroatrial situs solitus and the other with situs inversus); two patients with venous abnormalities (one with azygous continuation of the inferior vena cava and the other with bilateral iliac/femoral vein occlusion). Transjugular BMV was successful in all 10 patients (mean mitral valve area increasing from 0.68 +/- 0.17 to 1.92 +/- 0.40 cm(2); range, 1.56-2.76 cm(2)); it was quick (mean total fluoroscopy time, 10.5 +/- 2.7 min; range, 7.3-15.2 min); and it was safe (no major or minor complications except one patient who developed severe mitral regurgitation that only required medical therapy). The jugular approach to BMV overcomes many of the technical problems caused by anatomic changes that are encountered in transfemoral BMV and complements the latter approach.
