Telmisartan Plus Amlodipine as the Preferred Initial Combination in Newly Diagnosed Indian Patients with Hypertension: An Expert Consensus Statements.

INTRODUCTION: Hypertension (HTN) remains one of the most important risk factors for cardiovascular (CV) diseases and a leading cause of mortality worldwide. Despite improvement in detection and treatment, poor blood pressure (BP) control rates are observed globally. The situation in India is alarming with only 22.5% of patients maintaining their BP under control. Initiating early and effective treatment for HTN helps control BP within normal limits and reduces associated health risks. In India, currently, there are no guidelines on the choice of dual combination treatment that can be considered an initial treatment for newly diagnosed HTN patients to achieve effective BP control and reduce CV risks. OBJECTIVE: To provide consensus recommendations for preferred initial combinations in newly diagnosed Indian patients with HTN. METHODOLOGY: A core group of 100 experts with HTN expertise conceptualized and formulated the four key questions based on answerability, effectiveness, potential for translation to clinical practice, novelty, and potential impact on the healthcare burden. A mix of Delphi and Child Health and Nutrition Research Initiative (CHNRI) methods was adopted for acceptance or refusal of recommendations. Likert scale 1-9 was used for scoring. A score of ≥7 was considered "statement accepted," >6.50 "near to acceptance" and <6.50 "not accepted." A vote of ≥7 by at least two-thirds of the experts (66.66%) was mandatory for acceptance of the recommendation. CONCLUSION: Combination therapy could be necessary for a majority of newly diagnosed Indian patients for effective BP control. It can manage HTN with better clinical outcomes. Based on mean rating scores from experts, telmisartan plus amlodipine can be considered the preferred initial combination in the management of newly diagnosed Indian patients with HTN to achieve better BP control and improve CV outcomes.

Hydropneumopericardium: A rare complication of pericardiocentesis.

Hydropneumopericardium is defined as the presence of air and water in the pericardial cavity. Several causes have been postulated which can lead to hydropneumopericardium including trauma, infections secondary to gas-producing bacilli, fistula formation, positive pressure ventilation or even spontaneously without an underlying cause in healthy adults and rarely after pericardiocentesis. We report an uncommon instance of hydropneumopericardium after pericardiocentesis in a 35-year-old man, which developed due to a leaky drainage system. It was immediately drained through the subxiphoid approach under echocardiographic guidance, and the patient was relieved. Hydropneumopericardium is an uncommon but easily diagnosable and avoidable complication of pericardiocentesis. It should be suspected whenever the patient develops increasing dyspnoea following a temporary relief by pericardiocentesis.

Spectrum of interstitial lung diseases and their association with pulmonary hypertension.

Interstitial lung diseases (ILDs) are an intriguing group of pulmonary disorders, which still require the study of epidemiological, genetic, pathophysiological, clinical, and radiological parameters. Pulmonary hypertension (PH) is an underreported complication in interstitial lung diseases which is associated with worse outcome. In our study, we have reported the spectrum of ILDs and estimated the prevalence of pulmonary hypertension among these subjects at a tertiary care centre. A cross-sectional study was performed in which demographical, clinical, radiological, and histological data of subjects with ILD, attending the department of Respiratory Medicine in the University was collected from 1st September 2018 to 31st August 2019. Serological tests were done wherever indicated. Standard criteria along with multidisciplinary opinion were needed to arrive at the final diagnosis. All subjects were screened for pulmonary hypertension via 2-D echocardiography. Mean pulmonary artery pressure ≥20 mmHg was used to define PH. In the defined period, 239 subjects were enrolled (58% females, n=141; mean age 52.38±13.40 years). A tissue diagnosis was obtained in 34% cases.  The most common ILD was hypersensitivity pneumonitis (32.2%), followed by autoimmune-ILD (31.4%), idiopathic pulmonary fibrosis (IPF) (15.9%) and sarcoidosis (12.6%), non-IPF idiopathic interstitial pneumonitis (2.1%) and rest 21 (5.9%) subjects were diagnosed as other types of ILD.  Pulmonary hypertension was seen in 46.0% of subjects.

The time to reversal of complete atrioventricular block and its predictors in acute ST-segment elevation myocardial infarction.

OBJECTIVE: The purpose of this study was to determine the time to reversal of complete AV block (CAVB) in ST-segment elevation myocardial infarction (STEMI) with various modalities of treatment and to examine the factors associated with early reversal of CAVB. METHODS: We prospectively assessed the STEMI patients complicated by CAVB. The mean time to reversal of CAVB was analyzed and compared according to the treatment received. Multivariate logistic regression analysis was performed to find the predictors of mortality. RESULTS: Of 3954 patients with STEMI, CAVB was present in 146(3.7%) patients. Inferior wall myocardial infarction (IWMI) was more commonly associated with CAVB than anterior wall myocardial infarction (AWMI) (74.7% vs 25.3%). The mean time to reversal of CAVB was 25.4 ± 35.5 h. It was significantly lower with the primary percutaneous coronary intervention (PCI) compared to thrombolysis (5.21 ± 10.54 vs 12.98 ± 17.14; p = 0.0001). Predictors of early reversal of CAVB were early presentation to hospital (<6 h) from symptom onset, presence of IWMI, any revascularization done, primary PCI performed in comparison to thrombolysis, and normal serum creatinine levels. The presence of older age, broader QRS complex, cardiogenic shock/heart failure, and elevated creatinine were independent predictors of mortality. The CAVB reverted in all the alive patients except one who required permanent pacemaker implantation. CONCLUSION: CAVB is uncommon in STEMI and it recovers in a vast majority of surviving patients. The time to reversal of CAVB in STEMI is lower with primary PCI compared to thrombolysis. Outcomes are poor without revascularization in such patients.

An unusual case of isolated right-sided infective endocarditis masquerading as non-resolving pneumonia.

Right-sided infective endocarditis in non-intravenous drug abusers and non-immunocompromised patients is rare. The diagnosis is difficult as it can present as a respiratory illness leading to delays in diagnosis and development of complications, which can be fatal. The standard Duke criteria may not be adequate for diagnosis. We present a patient with isolated right-sided infective endocarditis mimicking right lower lobe non-resolving pneumonia who did not respond to antitubercular therapy.

Syndrome 'Z': A Predictor of Angiographic Severity of Coronary Artery Disease in Patients of Acute Coronary Syndrome.

BACKGROUND: Owing to the growing evidence that the pathophysiology of obstructive sleep apnoea (OSA) and metabolic syndrome (MS) overlap considerably and both adversely impact cardiovascular health, we hypothesised that the presence of OSA with MS additively and adversely affect the severity of coronary artery disease (CAD). Exploration and understanding of this may have direct implications for the development of targeted, preventive strategies for CAD. Thus, this prospective study was aimed to determine the prevalence of 'Syndrome Z' in patients of MS who present with an acute coronary event and to correlate it with the angiographic severity of CAD in these patients. METHODS: The present study was a single centre, cross sectional study conducted in a university teaching hospital. In a span of 6 months, 922 patients with acute coronary syndromes (ACS) were screened for the study. Among these, 861 patients had no evidence of MS. The remaining 61 patients who were diagnosed to have MS were then subjected to an overnight sleep study. Only 58 had good sleep data so were included for further analysis. Angiographic parameters in terms of number of vessels involved and culprit lesions were noted and correlated with presence and absence of OSA and also with its severity based on the Apnoea/Hypopnoea Index (AHI). RESULTS: The prevalence of OSA positivity in patients with MS who presented with ACS was 34.5% (n=20). Most of the patients in the OSA negative group (78.9%, n=30) had disease limited to only one vessel while in the OSA positive group only a minority (15%, n=3) of patients had their disease limited to a single vessel (p=0.001). The number of lesions in the culprit vessel was also significantly less in the OSA negative group compared to the OSA positive group. While in the OSA negative group 68.4% (n=26) patients had a solitary lesion, followed by two and three lesions in 15.8% (n=6) of the patients each, multiple lesions were more common in OSA positive patients, involving 80% of cases (45.0%, n=9 with two lesions; 35.0%, n=7 with three lesions; only 20%, n=4 had a solitary lesion). CONCLUSIONS: Prevalence of 'Syndrome Z' is high in patients having MS presenting with ACS and it correlates with the angiographic severity of CAD.

Predictors of permanent pacemaker implantation following transcatheter aortic valve replacement-the search is still on!

Several anatomical, demographic, clinical, electrocardiographic, procedural, and valve-related variables can be used to predict the probability of developing conduction abnormalities after transcatheter aortic valve replacement (TAVR) that necessitate permanent pacemaker (PPM) implantation. These variables include calcifications around the device landing zone and in the mitral annulus; pre-existing electrocardiographic abnormalities such as left and right bundle branch blocks (BBB), first- and second-degree atrioventricular blocks, as well as bifascicular and trifascicular blocks; male sex; diabetes mellitus (DM); hypertension; history of atrial fibrillation; renal failure; dementia; and use of self-expanding valves. The current study supports existing literature by demonstrating that type 2 DM and baseline right BBB are significant predictors of PPM implantation post-TAVR. Regardless of the side of the BBB, this study demonstrated, for the first time, a linear association between the incidence of PPM implantation post-TAVR and every 20 ms increase in baseline QRS duration (above 100 ms). After a 1-year follow-up, patients who received PPM post-TAVR had a higher rate of hospitalization for heart failure and nonfatal myocardial infarction.

Complete atrioventricular block-an uncommon clinical presentation in an adult patient with proven dengue fever.

Dengue is a viral disease that clinically presents with fever, thrombocytopenia-related haemorrhagic complications and shock in its severest form. This female patient in her 40s primarily presented to the emergency department of the cardiac centre as syncopal attacks with a complete atrioventricular block. Temporary cardiac pacing as an emergency procedure helped to maintain cardiac rhythm and haemodynamics. A history of recent onset fever helped us to suspect and confirmed by serology for dengue pathology. Normal sinus rhythm was restored after 2 days, and we removed the temporary pacing. Cardiac arrhythmia did not recur in 6 months of follow-up. The aetiology for dengue-related cardiac arrhythmia is still not established. In the recovery phase from fever, complete heart block may show up as a primary presentation in the emergency. Its timely diagnosis and temporary pacing may allow spontaneous recovery. The inclusion of electrocardiography in dengue patient guidelines should help clinicians to dictate its treatment.

Sinus Node Dysfunction and Pulmonary Hypertension-"Double Trouble" with Lithium Therapy.

Lithium is considered a gold standard drug for the management of bipolar disorder and is a widely used mood-stabilizing drug in psychiatry practice. However, its side effects are of important concern. The narrow therapeutic index of lithium predispose to its toxicity/side effects, but various case reports and research has shown that adverse drug reactions can occur even in the therapeutic range. We present the case of a 56-year-old woman with no history of cardiac illness presenting with tachycardia-bradycardia syndrome along with moderate pulmonary hypertension. Patients recovered to sinus rhythm after withholding lithium therapy for 1 week while her mean pulmonary artery pressure remained the same at day 10 of drug withdrawal.

The unpredictable resorption of bioresorbable scaffolds-A tale of two ABSORBs.

Bioresorbable stents represent a revolutionary treatment for coronary artery disease. Such a device offers the prospect for complete naturalization of artery lumen after strut resorption and restoration of vasomotion while curtailing the duration of dual anti-platelet therapy. The prototype bioresorbable scaffold (BRS-ABSORB GT1) demonstrated good feasibility and safety in the initial studies compared to metallic drug eluting stent but later fell out of favor due to multiple report of stent thrombosis and target lesion failure. Unpredictable resorption of struts turned out to be one of the "Achilles heel" of the BRS and stent strut were still visible in vessel on optical coherence tomography (OCT) at 3 years. We report a case of differential resorption of two ABSORB BRS implanted simultaneously in the same patient by the same operator. Follow up coronary angiogram revealed only minimal plaques on right coronary artery (RCA) and left anterior descending artery (LAD). The BRS were identified on cine-angiogram by their radio-opaque markers at both ends. The OCT run in LAD artery revealed "ghost remnants" of BRS struts in LAD, whereas the RCA BRS had completely healed with minimal "ghost" struts. The ghost remnants of BRS resembled the original "Check box" appearance on OCT during the index implantation.

Hybrid Pulmonary Sequestration, Cystic Pulmonary Adenomatoid Malformation, and Dextrocardia: A Triple Whammy.

Pulmonary sequestration and cystic pulmonary adenomatoid malformation are rare congenital cystic disorders of the lungs. The presence of both the diseases in the same individual is therefore very uncommon. Pulmonary sequestration is a nonfunctional pulmonary tissue mass that derives its blood supply from systemic blood supply other than pulmonary circulation. Congenital cystic pulmonary adenomatoid malformation represents a mass consisting of abnormal bronchiolar air spaces and a deficiency of functional alveoli. This is the case report of a 9-year-old girl with intermittent fever, left-sided chest pain, and cough for the past 15 days along with recurrent coughs since childhood suggestive of hybrid pulmonary sequestration, congenital cystic adenomatoid malformation, and dextrocardia.

Reliability of Fractional Flow Reserve in Non-Infarct-Related Arteries in ST-Segment Elevation Myocardial Infarction Patients Undergoing a Pharmaco-Invasive Approach.

Objectives We investigated the reproducibility of fractional flow reserve (FFR) of significant stenoses (≥70% narrowing) in the non-infarct related artery (NIRA) during the pharmaco-invasive percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) within 24 hours of thrombolysis and at a follow up of 2-3 weeks. Background STEMI with multivessel disease has worse outcomes. The benefits of FFR-directed PCI of NIRA at the time of primary PCI are yet controversial. Assessing the hemodynamic severity of the NIRA may help in deciding the management strategy of these lesions, save time, and avoid complications. Methods Thirty-one patients undergoing PCI for STEMI under a pharmaco-invasive approach were prospectively recruited. The FFR measurements in 34 stenoses (≥70% diameter stenosis) were obtained immediately after PCI of the culprit stenosis and were repeated at a mean follow-up of 17.6 ± 3.55 (14-21) days. In addition, time to thrombolysis, time from symptom onset to PCI, left ventricular ejection fraction (LVEF), quantitative coronary angiographic measurements of the non-culprit stenoses, and thrombolysis in myocardial infarction (TIMI) flow were recorded. Results There was a significant change in FFR values at follow-up as compared to baseline (0.78 ± 0.08 (0.68-0.93) to 0.77 ± 0.08 (0.67-0.93)) (p = 0.014). In four of the lesions, the FFR values differed by >0.05 at follow-up. The follow-up FFR values led to a change in the management strategy in 5 out of 31 patients (15%) of the lesions. The TIMI flow, percentage diameter stenosis, minimum lumen diameter, and LVEF did not change. There were no predictors of this change in FFR values. Conclusions During the acute phase of STEMI, the severity of non-culprit coronary artery stenoses can not be reliably assessed by FFR. The prolonged jeopardized state of myocardium in pharmaco-invasive PCI as compared to primary PCI seems to be responsible.

Monitoring Macro- and Microcirculation in the Critically Ill: A Narrative Review.

Circulatory shock is a common and important diagnosis in the critical care environment. Hemodynamic monitoring is quintessential in the management of shock. The currently used hemodynamic monitoring devices not only measure cardiac output but also provide data related to the prediction of fluid responsiveness, extravascular lung water, and also pulmonary vascular permeability. Additionally, these devices are minimally invasive and associated with fewer complications. The area of hemodynamic monitoring is progressively evolving with a trend toward the use of minimally invasive devices in this area. The critical care physician should be well-versed with current hemodynamic monitoring limitations and stay updated with the upcoming advances in this field so that optimal therapy can be delivered to patients in circulatory shock.

Anticoagulation for Left Ventricle Thrombus-Case Series and Literature Review for Use of Direct Oral Anticoagulants.

Left ventricular thrombus is a known complication following acute myocardial infarction that can lead to systemic thromboembolism. To obviate the risk of thromboembolism, the patient needs anticoagulation in addition to dual antiplatelet therapy. However, combining antiplatelets with anticoagulants substantially increases the bleeding risk. Traditionally, vitamin K antagonists (VKAs) have been the sheet anchor for anticoagulation in this scenario. The use of direct oral anticoagulants has significantly attenuated the bleeding risk associated with anticoagulation for atrial fibrillation and venous thromboembolism. Furthermore, in patients with atrial fibrillation undergoing percutaneous coronary intervention, the use of direct oral anticoagulants (DOACs) in conjunction with antiplatelets has been found to be noninferior in reducing ischemic events while significantly attenuating the bleeding compared with VKA. After initial case reports, multiple observational and nonrandomized studies have now safely and effectively utilized direct oral anticoagulants for anticoagulation in left ventricular thrombus. Here, we report a series of two cases presenting with left ventricular thrombus following acute myocardial infarction. In this case series, we try to address the issues concerning the choice and duration of anticoagulation in the case of postinfarct left ventricular thrombus. Pending the results of large randomized control trials, the judicious use of direct oral anticoagulant is warranted when taking into consideration the ischemic and bleeding profile in an individualized approach.

Bempedoic Acid: An Emerging Therapy for Uncontrolled Low-Density Lipoprotein (LDL) Cholesterol.

Atherosclerotic cardiovascular disease (ASCVD) is a silent epidemic, which is progressing relentlessly across the globe. Developing countries such as India have a high prevalence of dyslipidemia and consequently a huge burden of coronary artery disease (CAD) and ASCVD. Low-density lipoprotein is regarded as the primary culprit in the genesis of ASCVD, and statins are the first line therapy for LDL-C lowering. Statin therapy has unequivocally demonstrated the benefit of lowering LDL-C in patients across the spectrum of CAD and ASCVD. Muscle symptoms and worsening of glycemic homeostasis could be challenges with statin therapy, especially with the use of high doses. A large fraction of patients are also unable to achieve their LDL goals with statins alone in clinical practice. Moreover, LDL-C goals have become aggressive over years, necessitating a combination of lipid lowering therapies. PCSK-9 inhibitors and Inclisiran have emerged as robust and safe lipid-lowering agents, but parenteral administration and high cost precludes their widespread use. Bempedoic acid is a novel lipid-lowering agent working upstream of statins by inhibiting the enzyme ATP citrate lyase (ACL). The drug produces an average LDL lowering of 22-28% in statin-naïve patients and 17-18% when given to preexisting statin users. Because skeletal muscles lack the ACL enzyme, there is minimal risk of muscle-related symptoms. In combination with ezetimibe, the drug synergistically reduced LDL-C by 39%. Moreover, the drug has no adverse effect on glycemic parameters and lowers hsCRP (inflammation) like statin. The series of four randomized CLEAR trials, involving >4000 patients, have shown consistent LDL lowering across the spectrum of ASCVD patients with or without background therapy. The large and only cardiovascular outcome trial of the drug (CLEAR Outcomes) has recently demonstrated a 13% reduction of MACE at 40 months. Rise in levels of uric acid (four times) and acute gout (three times) are more common compared to placebo with the drug, owing to competitive renal transportation by OAT 2. In a nutshell, Bempedoic acid represents a value addition to the inventory of dyslipidemia management.

A tale of two in stent restenosis in same patient: Surprising findings from optical coherence tomography.

Key Clinical Message: The morphology of in-stent restenosis (ISR) in drug eluting stents varies greatly from that of bare metal stents. Optical coherence tomography (OCT) is a useful aid for identifying the nature of ISR and planning the treatment accordingly, which may be by intravascular lithotripsy, cutting balloon or Rotablator, which can be used upfront if OCT shows calcified neoatherosclerosis. Abstract: Restenosis is the decrease in the diameter of the vessel lumen after the performance of percutaneous intervention (PCI), which may or may not involve the implantation of a stent. The morphology of in-stent restenosis (ISR) in drug eluting stents (DES) vary greatly from that of bare metal stents (BMS). We present the case of a 60-years-old lady, who was a follow up case of PCI of the left anterior descending artery with DES and left circumflex artery using BMS 16 years ago. Optical coherence tomography (OCT) revealed both neoatherosclerosis and neointimal hyperplasia in both DES as well as BMS. The morphology of ISR in DES differed from that of BMS. PCI and pharmacological strategies form the main stream of management in case of neointimal hyperplasia. Detection of pattern of ISR on OCT can direct the management of a particular patient, which may be by the use of adjunct devices like intravascular lithotripsy, cutting balloon and Rotablator, which can be used upfront if OCT shows calcified neoatherosclerosis.
