- Abstract
Loop diuretics, including torsemide, furosemide, bumetanide, and piretanide, act by inhibiting the sodium-potassium-chloride (Na
+ /K+ /2Cl- ) cotransporter in the thick ascending limb of the loop of Henle within the nephron. This mechanism is pivotal in managing fluid retention associated with conditions such as heart failure, cirrhosis, chronic kidney disease, and hypertension. A comprehensive understanding of how these diuretics uniquely target this transporter provides crucial insights into effectively addressing fluid overload across diverse clinical conditions., (© Journal of the Association of Physicians of India 2024.)- Published

- Abstract
The incidence of heart failure (HF) in India is estimated to be 0.5-1.7 cases per 1,000 people per year, and approximately 4,92,000-1.8 million new cases are detected every year. Despite the high rate of mortality associated with HF, most patients do not receive maximal guideline-directed medical therapy (GDMT). Current guidelines advocate early multidrug combination therapy with four classes of drugs, namely, beta-blockers (BBs), mineralocorticoid receptor antagonists (MRAs), angiotensin receptor-neprilysin inhibitors (ARNIs), and sodium-glucose transport protein 2 inhibitors (SGLT-2is), particularly in patients with heart failure with reduced ejection fraction (HFrEF). ARNIs reduce cardiac morbidity and mortality in patients with HFrEF. However, recent data indicated that only 4.8% of patients with HFrEF receive ARNI in India. Hence, at a national consensus on HF meeting, cardiology experts from India formulated a national consensus on the use of ARNI in HF based on current evidence and guidelines. The consensus states that ARNI should be used early in HF, particularly in de novo patients with HFrEF, and those with acute decompensated heart failure (ADHF), irrespective of the presence of low systolic blood pressure (SBP) or diabetes. Moreover, those with HFrEF on renin-angiotensin-aldosterone system (RAAS) inhibitors should be switched to ARNI to reduce the risk of repeated hospitalization for HF, worsening HF, and cardiac death, and to improve the quality of life (QoL). Starting ARNI during the first hospitalization is preferable, and it is safe and effective across all doses. ARNIs can also be used for secondary benefits in patients with preserved ejection fraction [heart failure with preserved ejection fraction (HFpEF)] and HF with mildly reduced EF [heart failure with mildly reduced ejection fraction (HFmrEF)]., (© Journal of the Association of Physicians of India 2024.)

- Abstract
Chronic kidney disease (CKD) is a major contributor to morbidity and mortality in India. CKD often coexists with heart failure (HF), diabetes, and hypertension. All these comorbidities are risk factors for renal impairment. HF and CKD are pathophysiologically intertwined, and the deterioration of one can worsen the prognosis of the other. There is a need for safe renal pharmacological therapies that target both CKD and HF and are also useful in hypertension and diabetes. Neurohormonal activation achieved through the activation of the sympathetic nervous system (SNS), the renin-angiotensin-aldosterone system (RAAS), and the natriuretic peptide system (NPS) is fundamental in the pathogenesis and progression of CKD and HF. Angiotensin receptor neprilysin inhibitor (ARNi), sodium-glucose cotransporter 2 inhibitors (SGLT-2i), and selective β1-blocker (B1B) bisoprolol suppress this neurohormonal activation. They also have many other cardiorenal benefits across a wide range of CKD patients with or without concomitant HF, diabetes, or hypertension. This consensus statement from India explores the place of ARNi, SGLT-2i, and bisoprolol in the management of CKD patients with or without HF and other comorbidities., (© Journal of the Association of Physicians of India 2024.)

- Abstract
Heart failure (HF) is a global health concern that is prevalent in India as well. HF is reported at a younger age in Indian patients with comorbidity of type 2 diabetes (T2DM) in approximately 50% of patients. Sodium-glucose cotransporter-2 inhibitors (SGLT2i), originally approved for T2DM, are new guideline-recommended and approved treatment strategies for HF. Extensive evidence highlights that SGLT2i exhibits profound cardiovascular (CV) benefits beyond glycemic control. SGLT2i, in conjunction with other guideline-directed medical therapies (GMDT), has additive effects in improving heart function and reducing adverse HF outcomes. The benefits of SGLT2i are across a spectrum of patients, with and without diabetes, suggesting their potential place in broader HF populations irrespective of ejection fraction (EF). This consensus builds on the updated evidence of the efficacy and safety of SGLT2i in HF and recommends its place in therapy with a focus on Indian patients with HF., (© Journal of the Association of Physicians of India 2024.)

- Abstract
In India, heart failure (HF) is an important health concern affecting younger age groups than the western population. A limited number of Indian patients receive guideline-directed medical therapy (GDMT). Selective β-1 blockers (BB) are one of the GDMTs in HF and play an important role by decreasing the sympathetic overdrive. The BB reduces heart rate (HR) reverse the adverse cardiac (both ventricular and atrial), vascular, and renovascular remodeling seen in HF. Bisoprolol, a β-1 blocker, has several advantages and can be used across a wide spectrum of HF presentations and in patients with HF and comorbid conditions such as coronary artery disease (CAD), atrial fibrillation (AF), post-myocardial infarction (MI), uncontrolled diabetes, uncontrolled hypertension, and renal impairment. Despite its advantages, bisoprolol is not optimally utilized for managing HF in India. This consensus builds on updated evidence on the efficacy and safety of bisoprolol in HF and recommends its place in therapy with a focus on Indian patients with HF., (© Journal of the Association of Physicians of India 2023.)

- Abstract
Heart failure is associated with an increased frequency of hospitalization, reduced life span, and greater risk to public health, thus posing a challenge. In India, torsemide is one of the commonly used loop diuretics for decongestion in heart failure. However, this use of torsemide, including its dosing, and up/down titration, is based on practical experience. Loop diuretic therapy for heart failure patients poses several dilemmas due to the lack of robust evidence based on which treatment decisions can be made. To guide physicians on the optimal use of torsemide in heart failure patients with or without renal impairment, a panel of expert cardiologists and nephrologists from India convened to develop this expert opinion document for the use of torsemide. This expert opinion on torsemide will pave the way for optimal management with loop diuretic therapy in real-world heart failure patients., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Chopra et al.)

- Abstract
Aims: The prevalence of premature coronary artery disease (CAD) in India is two to three times more than other ethnic groups. Untreated heterozygous familial hypercholesterolemia (FH) is one of the important causes for premature CAD. As the age advances, these patients without treatment have 100 times increased risk of cardiovascular (CV) mortality resulting from myocardial infarction (MI). Recent evidence suggests that one in 250 individuals may be affected by FH (nearly 40 million people globally). It is indicated that the true global prevalence of FH is underestimated. The true prevalence of FH in India remains unknown., Methods: A total of 635 patients with premature CAD were assessed for FH using the Dutch Lipid Clinical Network (DLCN) criteria. Based on scores, patients were diagnosed as definite, probable, possible, or no FH. Other CV risk factors known to cause CAD such as smoking, diabetes mellitus, and hypertension were also recorded., Results: Of total 635 patients, 25 (4%) were diagnosed as definite, 70 (11%) as probable, 238 (37%) as possible, and 302 (48%) without FH, suggesting the prevalence of potential (definite + probable) FH of about 15% in the North Indian population. FH is more common in younger patients, and they have lesser incidence of common CV risk factors such as diabetes, hypertension, and smoking than the younger MI patients without FH (26.32% vs.42.59%; 17.89% vs.29.44%; 22.11% vs.40.74%)., Conclusion: FH prevalence is high among patients with premature CAD admitted to a cardiac unit. To detect patients with FH, routine screening with simple criteria such as family history of premature CAD combined with hypercholesterolemia, and a DLCN criteria score >5 may be effectively used., (Copyright © 2019 Cardiological Society of India.

- Abstract
Background: The PANARrhythMia and Heart Failure Registry (PANARM HF) characterized demographic, clinical and interventional therapy indication profiles of cardiac arrhythmia (CA) and heart failure (HF) patients in India., Methods: Consulting Physicians (CP) who medically manage CA and HF patients enrolled patients with one or more of the following: syncope, pre-syncope, dyspnea, palpitation, fatigue and LV dysfunction. The CPs were trained by interventional cardiologists (IC) to identify CA/HF patients indicated for implantable device/radiofrequency ablation (RFA). 59 CP's, 16 IC's & 2205 patients from 12 cities participated. Demographic, clinical, device/RFA indication and referral-consultation profiles were created. IC's provided device/RFA recommendations based on these profiles., Results: The CA/HF distribution of patients was: HF - 58%, bradyarrhythmia - 15%, atrial fibrillation - 15%, other supraventricular tachyarrhythmia - 10% and ventricular tachycardia/fibrillation - 4.5%. 62% of the CA/HF population was male and 45% were below age 60. Coronary artery disease (52%), hypertension (44%), diabetes (30%) & myocardial infarction (20%) were prominent. 1011 (46%) of the CA/HF population were potential device/RFA candidates according to the IC's. However, only 700 (69%) of these patients were referred to the IC by the CP. Of referred patients, only 177 (25%) consulted the IC and were recommended therapy. Thus, 824 (83%) of patients indicated for interventional therapy were not advised therapy or did not opt for it., Conclusion: The India PANARM HF study provides new information and insights into the demographic, clinical, interventional therapy, referral and consultation pattern profiles of CA/HF patients in India., (Copyright © 2016.

- Abstract
Anomalies of the supra-diaphragmatic portion of the inferior caval vein are rare in patients with normal sinus. We recently encountered a patient with situs solitus and infundibular pulmonic stenosis who had bifurcation of the supra-diaphramatic portion of the inferior caval vein with anomalous high insertion of one portion into the mid-right atrium. The other division joined the coronary sinus which also received a persistent left superior caval vein and left hepatic veins. Biplane angiography was used to delineate the anatomy. Pre-operative delineation is required as this anomaly complicates cardio-pulmonary bypass.

- Abstract
Thirty-three surgically proven cases of constrictive pericarditis were studied pre-operatively by echocardiography for left atrial dilatation and 18 of them underwent post-operative study at a mean follow-up period of 229 +/- 105 days. The degree of left atrial dilatation in these patients was compared with patients of restrictive cardiomyopathy (n = 8) and sex matched controls of similar age (n = 33). Significant left atrial dilatation was present in patients of constrictive pericarditis compared to controls and it was of a similar or greater degree compared to patients of restrictive cardiomyopathy (the left atrium to aorta ratio was 1.7 +/- 0.31, 1.53 +/- 0.18 and 1.07 +/- 0.1, in constrictive pericarditis, restrictive cardiomyopathy and controls, respectively, P = NS for constrictive pericarditis vs. restrictive cardiomyopathy and P < 0.001 for constrictive pericarditis vs. controls). There was no correlation of degree of left atrial dilatation with clinical and hemodynamic variables. Postoperatively, there was regression of left atrial size in patients with normal hemodynamics (n = 12, pre- vs. post-operative left atrium to aorta ratio 1.65 +/- 0.23 vs. 1.32 +/- 0.14, P < or = 0.001) and persisting or increasing left atrial dilatation in patients with persisting hemodynamic abnormality (n = 6, left atrium to aorta ratio 1.66 +/- 0.23 vs. 1.82 +/- 0.15, P = NS). We conclude that significant left atrial dilatation is a consistent echocardiographic feature of constrictive pericarditis. Hemodynamic normalization following successful pericardiectomy is associated with regression of atrial size.

- Abstract
Doppler echocardiographic characteristics of 57 normally functioning Sorin prosthetic valves (a tilting valve) in the mitral position were studied in the early postoperative period. The three valve sizes (in mm) studied were: 25 (n = 15), 27 (n = 32) and 29 (n = 10). The mean gradients (mmHg) and the valve area (Sq cm) calculated by pressure half time method) for the three valve sizes were 3.46 +/- 1.69 and 2.49 +/- 0.26; 3.46 +/- 1.25 and 2.57 +/- 0.44; and 3.2 +/- 1.23 and 2.55 +/- 0.41; respectively. There was no significant difference in gradients and valve area between the three sizes, variations in pressure half time and therefore the calculated valve area was large. Color Doppler evaluation revealed a bifid nonturbulent jet directed anteriorly towards the interventricular septum. 12 patients (20%) had mild valvar and 7 (12%) had paravalvar mitral regurgitation (mild in 5 and moderate in 2) without any associated prosthetic valve dysfunction. The paravalvar regurgitation persisted in all the 5 patients restudied at 5-12 months postoperatively. Sorin prosthetic valves have similar gradients and valve area when compared to other disc valves. The incidence of of paravalvar regurgitation was slightly higher in our series. The limitations of Doppler derived gradients and area of prosthetic valve are discussed.

- Abstract
We studied 33 surgically proven cases of constrictive pericarditis during the period 1989-1991 by color Doppler echocardiography and angiography to look for incidence and postoperative outcome of atrioventricular regurgitation. The mean age was 27.2 + 16.5 years (21 males, 12 females). There was a very high incidence of mitral (79%, trivial in 13, mild in 11 and moderate in 2) and tricuspid (73%, trivial in 7, mild and moderate in 6 each and severe in 5) regurgitation. There was good correlation between 'color Doppler' and angiography for detection and quantification of these regurgitations (r = 0.89 for mitral and 0.76 for tricuspid regurgitation, respectively). There were no preoperative clinical or hemodynamic predictors for the incidence or severity of these regurgitations. Immediate postoperative (7-10 days) evaluation by color Doppler did not show any change in these regurgitations. A follow-up study (by color Doppler and angiography) in 18 patients at a mean period of 229 + 105 days revealed regression of these regurgitations by at least 1 grade in 50% of patients. Patients with persisting regurgitations had persisting hemodynamic abnormality and relatively longer duration of symptoms. The presence of atrio-ventricular regurgitations should not be taken as evidence favoring diagnosis of restrictive cardiomyopathy and against that of constrictive pericarditis. The mechanism of these regurgitations is not clear to us.
