Heart failure (HF) is a progressive clinical syndrome characterized by the inability of the heart to efficiently perform its circulatory function. The burden of HF has been increasing globally, including in India, leading to higher mortality rates, hospitalizations, and diminished quality of life. The incidence of HF in India is expected to rise due to factors such as an aging population, increased cardiovascular risk factors, and the persistence of diseases like rheumatic heart disease. Despite advances in medical therapy, HF continues to impose a significant healthcare and economic burden. To understand the underlying substrate of hypertension leading to HF, a group of 20 experts from various regions of India participated in a national-level expert panel meeting. The experts reviewed scientific literature and discussed the management of hypertension, dyslipidemia, and HF in the Indian context. Consensus statements were developed based on the discussions and approved by all participating experts. Key findings include early onset of end-organ damage and microalbuminuria in Indian hypertensive patients, elevated sympathetic overactivity in certain subgroups, and the efficacy of combination therapies and calcium channel blockers. The management of dyslipidemias was found to be suboptimal, with physician inertia and concerns about side effects being barriers to guideline-directed therapy. Recommendations were made to improve physician education and patient awareness. In HF management, challenges were identified, and strategies were proposed to optimize guideline-directed medical therapy and implement newer therapies such as angiotensin receptor-neprilysin inhibitors (ARNIs) and sodium-glucose cotransporter-2 (SGLT2) inhibitors. This consensus document provides valuable insights and recommendations for managing hypertension, dyslipidemia, and HF in the Indian population, with the potential to improve patient outcomes and reduce the burden of HF.

In heart failure, sympathetic overdrive is evidenced by norepinephrine spillover, receptor level changes, etc. Beta-blockers continue to be the cornerstone of treatment in patients with chronic heart failure due to their ability to counteract sympathetic overdrive. Extensive clinical research has demonstrated that long-term beta-blocker treatment with metoprolol succinate, carvedilol, or bisoprolol enhances left ventricular function and reverses left ventricular remodeling, decreases hospitalization risk, and increases survival. The aim of this consensus paper is to identify patient profiles, initiation or up-titration of beta-blockers and benefits of chirally pure beta-blocker in patients with heart failure. This expert consensus will ensure precise implementation of beta-blockers in heart failure as a part of guideline-directed medical therapy., (© Journal of the Association of Physicians of India 2024.)

The rapidly increasing burden of hypertension is responsible for premature deaths from cardiovascular disease (CVD), renal disease, and stroke, with a tremendous public health and financial burden. Hypertension detection, treatment, and control vary worldwide; it is still low, particularly in low- and middle-income countries (LMICs). High blood pressure (BP) and CVD risk have a strong, linear, and independent association. They contribute to alarming numbers of all-cause and CVD deaths. A major culprit for increased hypertension is sympathetic activity, and further complications of hypertension are heart failure, ischemic heart disease (IHD), stroke, and renal failure. Now, antihypertensive interventions have emerged as a global public health priority to reduce BP-related morbidity and mortality. Calcium channel blockers (CCB) are highly effective vasodilators. and the most common drugs used for managing hypertension and CVD. Cilnidipine, with both L- and N-type calcium channel blocking activity, is a promising 4th generation CCB. It causes vasodilation via L-type calcium channel blockade and inhibits the sympathetic nervous system (SNS) via N-type calcium channel blockade. Cilnidipine, which acts as a dual L/N-type CCB, is linked to a reduced occurrence of pedal edema compared to amlodipine, which solely blocks L-type calcium channels. The antihypertensive properties of cilnidipine are very substantial, with low BP variability and long-acting properties. It is beneficial for hypertensive patients to deal with morning hypertension and for patients with abnormal nocturnal BP due to exaggerated sympathetic nerve activation. Besides its BP-lowering effect, it also exhibits organ protection via sympathetic nerve inhibition and renin-angiotensin-aldosterone system inhibition; it controls heart rate and proteinuria. Reno-protective, neuroprotective, and cardioprotective effects of cilnidipine have been well-documented and demonstrated., (© Journal of the Association of Physicians of India 2024.)

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), β-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)., (© Journal of the Association of Physicians of India 2011.)

Background: Primary Sjogren's Syndrome (pSS) with Hypokalemic Periodic Paralysis(HPP) whether an association or a different clinical subset needs review., Aim: To generate a consensus on the importance of pharmaco-invasive therapy for STEMI patients when primary PCI cannot be expeditiously performed in metro and tier-I cities in India., Methodology: A total of 8 expert panel groups comprising 48 experts from Cardiology specialty in India were convened. These groups individually reviewed the evidence on various types of fibrinolytic agents, their importance in STEMI management in general and in India and finally shared their experience and views on the importance of pharmaco-invasive therapy during STEMI management in metro and tier-I cities in India. Individual group opinions were compiled into one document and the consensus was finalized after it was approved by all panel members., Results: The board concluded that in metro and tier-I cities, pharmaco-invasive therapy, preferably using third generation fibrinolytic agents such as Reteplase and Tenecteplase, should be instituted to all patients for whom a delay in primary PCI of greater than 120 minutes from the time of ECG confirmation is anticipated. This will enhance the time window to preserve the myocardium from further damage arising due to patient related, transportation related or in- hospital delays. The present article also highlights the importance of third generation fibrinolytics in pharmaco-invasive therapy and looks at strategies to augment their use., Conclusion: Pharmaco-invasive therapy is recommended in STEMI patients even in metro and tier-I cities of India, where delay in access to PCI is anticipated, in place of a strategy of promoting only primary PCI., (© Journal of the Association of Physicians of India 2011.)

Objective: Primary objective of this study was to compare the efficacy of Prasugrel vs. Clopidogrel in the patients with acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI) by measuring inhibition of platelet aggregation after loading and maintenance dose of both the drugs. The patients were also assessed for safety of the drugs., Methods: This was a randomised, double-blind, double-dummy, comparative, multicentric clinical trial in patients with acute coronary syndrome (unstable angina, non-ST elevation MI and ST elevation MI) undergoing PCI. The patients were randomly assigned to receive prasugrel (loading dose of 60 mg followed by maintenance dose of 10-mg once daily) or clopidogrel (loading dose of 300 mg followed by maintenance dose of 75 mg once daily) for a period of 12 weeks. All the patients were co-prescribed aspirin 325 mg with both the drugs. The primary efficacy end point in this study was percentage inhibition of ADP induced platelet aggregation (IPA) at 4 +/- 1 hours after the loading dose and at 30 +/- 3 days during maintenance treatment. The platelet aggregation of both the drugs was measured by whole blood aggregometer using 10 mmol of ADP as an aggregant. Though this study was not powered to see the difference in clinical efficacy parameters, the patients were observed for the incidence of nonfatal MI, nonfatal stroke, re-hospitalization, death, or need for urgent revascularization due to a cardiac ischemic event at days 30 and 90 during the study. The safety of study drugs were evaluated by incidence of major bleeding, reported adverse drug reaction and alterations of any laboratory parameters., Result: A total of 220 patients were enrolled at 11 centres across India. Ten patients were given the loading dose of prasugrel or clopidogrel but did not underwent PCI due to change in investigator's decision to go for PCI. Out of 210 eligible patients, 21 patients were discontinued during the study. 157 patients were evaluated for platelet inhibition after loading dose at 4 hours and 150 patients at day 30 during maintenance phase of antiplalelet therapy. The investigators could not perform this test in remaining patients due to urgency and criticality of the patients. 189 patients were observed for the incidence of nonfatal MI, nonfatal stroke, rehospitalisation, urgent revascularisation or death due to a cardiac ischemic event. All eligible patients who received at least a loading dose were evalauted for safety. In prasugrel group, 85 and 77 patients were evaluated for IPA at 4 hours and day 30 respectively whereas in clopdogrel group 72 and 73 patients were tested for IPA at 4 hours and at 30 days. Patients in prasugrel group have demonstrated significantly higher inhibition of platelets as compared to clopidogrel group (82.5% vs 71.1%) at 4 hours and at 30 days (84.1% vs 67.4%). The difference in inhibition of platelets between prasugrel and clopidogrel after loading dose and maintenenace dose was statistically significant (p < or = 0.01). The patients were also evaluated for drug hyporesponsiveness to antiplatelet therapy if IPA was < 20% at day 30 from the baseline. More patients on prasugrel have shown response to antiplatlet therapy than on clopidogrel (97.4% vs 87.6%). The difference between the two groups was statistically significant (p < 0.05). There was no difference observed during the study in the incidence of nonfatal MI, nonfatal stroke, death, rehospitalisation or need for urgent revascularisation due to a cardiac event between prasugrel and clopidogrel. Both the drugs were found to be to be well tolerated and have comparable safety profile., Conclusion: This study suggests that prasugrel is more effective than clopidogrel as an anti platelet drug as evident by inhibition of platelet aggregation. More patients on clopidogrel are likely to have poor response to therapy as compared to prasugrel. Both the drugs were well tolerated and have comparable safety profile.

Metoprolol is a widely used cardioselective beta-blocker. However, like all other beta-blockers it is also a racemic mixture of R- and S- isomers. The beta 1 blocking activity (cardioselectivity) of metoprolol resides in S-isomer while R-isomer exhibits beta 2 blocking activity. As both these isomers have different pharmacological properties, racemic metoprolol can be considered a combination of two different drugs in a fixed 1:1 ratio. The needless administration of the non beta-blocking R-enantiomer that makes up 50% of racemate actually puts the patient at an increased risk of side-effects, drug interactions and loss of cardioselectivity with up-titration of dosing. Clinical experience with chirally pure S-metoprolol at half the dose of racemate has shown it to be as effective as racemate in the treatment of patients with hypertension and angina. S-metoprolol has been shown to be effective and well-tolerated in patients with coexisting diabetes, COPD, and hyperlipidaemia. This confirms higher cardioselectivity of S-metoprolol in clinical settings. Less interaction potential of S-metoprolol compared to R-isomer further makes it a sensible choice in patients taking CYP2D6 inhibitors or in patients with heart failure or hepatic insufficiency. This article reviews differing properties of two isomers of metoprolol with focus on clinical experience with S-metoprolol.
