Lipid Association of India 2023 update on cardiovascular risk assessment and lipid management in Indian patients: Consensus statement IV.

OBJECTIVE: In 2016, the Lipid Association of India (LAI) developed a cardiovascular risk assessment algorithm and defined low-density lipoprotein cholesterol (LDL-C) goals for prevention of atherosclerotic cardiovascular disease (ASCVD) in Indians. The recent refinements in the role of various risk factors and subclinical atherosclerosis in prediction of ASCVD risk necessitated updating the risk algorithm and treatment goals. METHODS: The LAI core committee held twenty-one meetings and webinars from June 2022 to July 2023 with experts across India and critically reviewed the latest evidence regarding the strategies for ASCVD risk prediction and the benefits and modalities for intensive lipid lowering. Based on the expert consensus and extensive review of published data, consensus statement IV was commissioned. RESULTS: The young age of onset and a more aggressive nature of ASCVD in Indians necessitates emphasis on lifetime ASCVD risk instead of the conventional 10-year risk. It also demands early institution of aggressive preventive measures to protect the young population prior to development of ASCVD events. Wide availability and low cost of statins in India enable implementation of effective LDL-C-lowering therapy in individuals at high risk of ASCVD. Subjects with any evidence of subclinical atherosclerosis are likely to benefit the most from early aggressive interventions. CONCLUSIONS: This document presents the updated risk stratification and treatment algorithm and describes the rationale for each modification. The intent of these updated recommendations is to modernize management of dyslipidemia in Indian patients with the goal of reducing the epidemic of ASCVD among Indians in Asia and worldwide.

An 85-Year-Old Man with Fever, Dyspnea, and Dry Cough Diagnosed with Idiopathic Hypereosinophilic Syndrome, Successfully Treated with High-Dose Corticosteroids.

BACKGROUND Idiopathic hypereosinophilic syndrome (I-HES) is a rare disease diagnosed as absolute eosinophil count >1500 cells/µl and end-organ involvement attributable to tissue eosinophilia with no secondary cause of underlying eosinophilia. The mean age of presentation for I-HES is 44 years. The skin, lungs, and gastrointestinal (GI) system are most common sites of presenting manifestations, including fatigue, cough, dyspnea, myalgias, angioedema, rash, fever, nausea, and diarrhea. Although cardiac and neurologic symptoms are less common at presentation, they can be life-threatening. CASE REPORT We report the case of an 85-year-old man who presented with fever, malaise, and loss of appetite for 3 weeks, followed by dyspnea and dry cough for 2 weeks. His absolute eosinophil count was 9000 cells/µl, which was not responding to empirical antibiotic therapy, with worsening of symptoms, suggesting a non-infective origin. He was then extensively evaluated to establish underlying an etiology for specific treatment, which was negative for common causes like atypical infections, malignancy, and autoimmune disorders. He was then started on corticosteroid therapy to overcome an exaggerated immune response and reduce inflammation-related injury, to which he responded well. On follow-up, hypereosinophilia was fully cured, with reversal of end-organ involvement including myocarditis and pneumonitis. CONCLUSIONS This report shows that idiopathic HES can present with various clinical features and that accurate diagnosis, excluding known causes of eosinophilia, and early management are essential to prevent long-term organ damage. Our patient responded to prompt treatment with high-dose corticosteroids.

Clinical profile and outcome of cardiac manifestations in patients presenting with multisystem inflammatory syndrome in children associated with SARS-CoV-2 infection.

Multisystem inflammatory syndrome in children (MIS-C) can cause significant morbidity and mortality in children. This study was conducted to assess the pattern and outcome of cardiac abnormalities in MIS-C. This retrospective study was conducted in children with MIS-C between 1 month and 18 years. We enrolled 53 children with a mean age of 7.78 ± 4.62 years. Overall, 35.8% of children with MIS-C had cardiac manifestations in the form of coronary artery abnormalities (CAAs) or left ventricular (LV) dysfunction. Younger age (P 0.009) and high C-reactive protein at admission (P = 0.001) were significant predictors of cardiac involvement. CAAs were seen in 11.3% of children. On follow-up, 67% and 83% of children showed regression of CAA at 1 and 6 months, respectively. 24.5% of patients had presented with LV dysfunction. LV ejection fraction improved significantly at 1 month (P = 0.002) and 6 months (P = 0.001). Cardiac outcomes in MIS-C were favorable with timely identification and treatment.

Role of two-dimensional strain echocardiographic parameters in suspected acute coronary syndrome patients with initial non-diagnostic electrocardiogram and troponins: An observational study.

INTRODUCTION: Diagnosis of acute coronary syndrome (ACS) is often challenging especially in presence of initial normal troponins and non-specific electrocardiogram. The index study aimed at determining the diagnostic value of strain echocardiography in patients with suspected ACS but with non-diagnostic electrocardiogram and echocardiography findings. METHODS: The study was conducted on 42 patients with suspected ACS and non-diagnostic electrocardiograms, normal quantitative troponin-T levels, and left ventricular function. All patients underwent conventional and 2D-strain echocardiography followed by coronary angiography, within 24 h of admission. Patients with regional wall motion abnormalities (RWMA), valvular heart disease, suspected myocarditis, and past coronary artery disease (CAD) were excluded. RESULTS: Amongst the global strains, the global circumferential strain (GCS) was significantly reduced (p = .014) amongst those with significant CAD on angiography as opposed to global longitudinal strain (GLS) which was similar in the two groups (p = .33). The GCS/GLS ratio was also significantly reduced in patients with significant CAD compared to those with normal/mild disease on coronary angiography (p = .025). Both the parameters had good accuracy in predicting significant CAD. GCS displayed a sensitivity of 80% and a specificity of 86% at an optimal cut-off 31.5% (AUROC: .93, 95% CI: .601-1.000; p = .03), and likewise GCS/GLS ratio had a sensitivity of 80% and a specificity and 86% at a cut-off of 1.89% (AUROC: .86, 95% CI: .592-1.000; p = .049). GLS and peak atrial longitudinal strain (PALS) did not differ significantly in patients with/without significant CAD (p = .32 and .58, respectively). CONCLUSION: GCS and GCS/GLS ratio provides incremental value in comparison to GLS, PALS, and tissue Doppler indices (E/e') in patients with suspected ACS and non-diagnostic electrocardiogram and troponins. GCS at cut-off of >31.5% and GCS/GLS ratio >1.89 can reliably exclude patients with significant CAD in this setting.

Prevalence and predictors of lower extremity atherosclerotic disease amongst high-risk patients using ankle brachial index.

INTRODUCTION: The prevalence of lower extremity artery disease (LEAD) continues to increase worldwide. This is expected to translate into logarithmic rise in lower-limb amputations especially in the developing world. Majority of patients suffering from LEAD remain asymptomatic until late and are vulnerable to limb-threatening complications unless actively screened and treated. METHODS: This was a prospective, single-center, observational study to determine the prevalence and predictors of LEAD. Patients with known atherosclerotic vascular disease (but not known LEAD) or those at risk were enrolled. All underwent ankle brachial index (ABI) measurement as per the standard protocol. A threshold of ABI ≤0.90 was taken to diagnose LEAD. RESULTS: A total of 1000 patients were enrolled. The mean age of the group was 61.4 ± 10.0 years and the prevalence of LEAD was 10.2%. Amongst those who had LEAD, the majority of patients (69.6%) had no symptoms. The prevalence of LEAD in diabetic population in our study was 13.2% and it was 30.9% in coronary artery disease patients . Factors independently linked to LEAD on regression analysis included advanced age, presence of diabetes, smoking history, lower serum HDL and a lower ejection fraction. CONCLUSIONS: The vast majority of patients suffering from LEAD are asymptomatic. Early diagnoses and institution of appropriate medical and physical therapy can prevent excess morbidity and mortality due to LEAD. Factors independently linked to LEAD are advanced age, presence of diabetes, smoking history, lower serum HDL and a lower ejection fraction. The presence of either of these should signal undertaking of appropriate steps to unmask underlying LEAD.

Role of Sildenafil in Management of Pediatric Acute Respiratory Distress Syndrome.

Acute respiratory distress syndrome (ARDS) has high mortality and multiple therapeutic strategies have been used to improve the outcome. Inhaled nitric oxide (INO), a pulmonary vasodilator, is used to improve oxygenation. This study was conducted to determine the role of sildenafil, an oral vasodilator, to improve oxygenation and mortality in pediatric ARDS (PARDS). The prevalence of pulmonary hypertension in PARDS was studied as well. Inclusion criteria included children (1-18 years) with ARDS requiring invasive ventilation admitted to the pediatric intensive care unit of a teaching hospital in Northern India over a 1-year period of time. Thirty-five patients met the inclusion criteria. Pulmonary arterial pressure (PAP) was determined by echocardiogram. Patients with persistent hypoxemia were started on oral sildenafil. The majority of patients (77%) had a primary pulmonary etiology of PARDS. Elevated PAP (>25 mm Hg) was detected in 54.3% patients at admission. Sildenafil was given to 20 patients who had severe and persistent hypoxemia. Oxygenation improved in most patients after the first dose with statistically significant improvement in PaO 2 /FiO 2 ratios at both 12 and 24 hours following initiation of therapeutic dosing of sildenafil. Improvement in oxygenation occurred irrespective of initial PAP. Outcomes included a total of 57.1% patients discharged, 28.6% discharged against medical advice (DAMA), and a 14.3% mortality rate. Mortality was related to the severity of PARDS and not the use of sildenafil. This is the first study to determine the effect of sildenafil in PARDS. Sildenafil led to improvement in oxygenation in nearly all the cases without affecting mortality. Due to unavailability of INO in most centers of developing countries, sildenafil may be considered as an inexpensive alternative in cases of persistent hypoxemia in PARDS. We recommend additional randomized controlled trials to confirm the effect of sildenafil in PARDS as determined in this study.

Clinical profile of patients with cardiac amyloidosis in India.

Limited data exists on patients with cardiac amyloidosis (CA) in India, due to underdiagnosis and late presentation. We present single centre data from 13 patients over a 4 year period with a median age of 65 years. A majority presented with symptomatic heart failure (69%) and eight patients had confirmed AL amyloidosis. At the end of the follow up period, 46% patients died, with 30% of the overall cohort dead within six months. Among the survivors, 71% continue to have NYHA grade III/IV symptoms. A suggested algorithm for earlier diagnosis in resource constrained settings is also presented.

Autoimmune polyendocrine syndrome II presenting paradoxically as Takotsubo cardiomyopathy: a case report and reappraisal of pathophysiology.

BACKGROUND: Takotsubo cardiomyopathy (TCM) is a rare disease entity characterized by acute, non-ischemic, reversible myocardial dysfunction that mimics acute myocardial infarction. Activation and excessive outflow of sympathetic nervous system are believed to be central to the figure in the disease pathogenesis. Adrenocortical hormones potentiate the systemic actions of sympathetic nervous system and accordingly are essential for regulation of myocardial function. We present an unusual case of a middle-aged woman with primary adrenal insufficiency who presented paradoxically with TCM. CASE PRESENTATION: A 50-year-old woman with past history of hypothyroidism presented to emergency department with history of acute chest pain and syncope. There was no significant drug history or history of an emotional or physical stimulus prior to admission. Prominent pigmentation over the tongue and skin creases of hands were noted. On presentation, she was in shock and had ventricular tachycardia which required electrical cardioversion. The subsequent electrocardiogram demonstrated diffuse T-wave inversions with prolonged QTC. There was apical hypokinesia on echocardiogram, and cardiac biomarkers were elevated. There was persistent inotropic requirement. She had marked postural symptoms, and a postural blood pressure drop of 50 mm Hg was present. Initial laboratory parameters were significant for hyperkalemia (7.8 mEq/L) and hyponatremia (128 mEq/L). These findings prompted evaluation for adrenal insufficiency which was confirmed with appropriate tests. Autoimmune polyendocrine syndrome II was thus diagnosed based on the above findings. Coronary angiography revealed normal coronaries. The diagnoses of TCM was established in accordance with the International Takotsubo Diagnostic Criteria. She was started on stress dose steroid replacement therapy and improved dramatically. At one month of follow-up, the patient is asymptomatic, and there was normalization of her left ventricular function. CONCLUSIONS: Intricate relationship and interplay exist between the steroid hormones and catecholamines in the pathogenesis of TCM. Steroid hormones not only potentiate the actions of catecholamines, but they also regulate and channelize catecholaminergic actions preventing their deleterious effects on the cardiac tissue. Hence, both steroid deficiency and exogenous steroid replacement may precipitate TCM. Evidence from more such cases and larger perspective studies in future will further improve our understanding of this complex disease process and its myriad associations.

Effect of environment and season on acute decompensated heart failure: Data from low-to middle-income country.

OBJECTIVES: The environmental effect in heart failure (HF) patients is well established. However, the data is limited from low-to middle-income countries like India. This study determined the impact of environment on acute decompensated HF (ADHF) admissions and mortality in India. METHODS: Retrospectively, the data of all HF patients admitted between April 2017 and March 2019 was accessed through electronic hospital records. Simultaneously, the environmental-related data was collected from the central pollution control board. RESULTS: The study included 4561 patients of ADHF. The peak of monthly ADHF events (admission and mortality) was observed during the chilly month (January) while the lowest rates were observed in summer months (May-June). The most significant factor correlating inversely with the monthly ADHF admission (r = -0.78, p = 0.003) and mortality (r = -0.65, p = 0.004) was the maximum air temperature, and it was found to be the independent predictor for both ADHF mortality [t = -2.78, ß = -0.84; 95%CI(-6.0 to -0.6), p = 0.021] and admission [t = -4.83, ß = -0.91; 95%CI(-19.8 to -6.9), p = 0.001]. The above correlation was better seen in the elderly subset and male gender. Humidity and the air pollution attributes did not have a significant correlation with ADHF admission or mortality. CONCLUSION: In conclusion, even in low-to middle-income country like India, a periodic effect of season was demonstrated for ADHF mortality and admission, with a peak in ADHF events noted during winter months especially in the regions having extremes of seasons. Air pollution could not affect the ADHF outcome for which further studies are needed.

Impact of a nurse-led teleconsultation strategy for cardiovascular disease management during COVID-19 pandemic in India: a pyramid model feasibility study.

OBJECTIVE: The COVID-19 pandemic necessitated the use of telemedicine to maintain continuity of care for patients with cardiovascular diseases (CVDs). This study aimed to demonstrate the feasibility of implementing a nurse-led teleconsultation strategy for CVD management during the COVID-19 pandemic in India and evaluated the impact of nurse-led teleconsultations on patient treatment satisfaction. DESIGN, SETTING AND PARTICIPANTS: We developed a two-stage teleconsultation strategy and tested the feasibility of implementing a nurse-led teleconsultation strategy to manage CVD in a northern state (Punjab) in India. A multidisciplinary team of experts developed the treatment protocol used for teleconsultations to manage CVD. Nurses were trained to provide teleconsultation, triaging of patients and referrals to the physicians. Patients with CVD who had an outpatient visit or hospitalisation between September 2019 and March 2020 at the Dayanand Medical College Hospital, Ludhiana, India, were contacted by phone and offered teleconsultations. Telemedicine strategy comprised: stage 1 nurse-led teleconsultations and stage 2 physician-led teleconsultations. Descriptive analysis was performed to report the proportion of patients triaged by the two-stage telemedicine strategy, and patient's clinical characteristics, and treatment satisfaction between the nurse-led versus physician-led teleconsultations. RESULTS: Overall, nurse-led stage 1 teleconsultations were provided to 12 042 patients with CVD. The mean (SD) age of the participants was 58.9 years (12.8), and men were 65.4%. A relatively small proportion of patients (6.3%) were referred for the stage-2 physician-led teleconsultations and of these only 8.4% required hospitalisations. During stage 1 nurse-led teleconsultations, patients were referred to the physicians due to uncontrolled diabetes (24.9%), uncontrolled hypertension (18.7%) and congestive heart failure (16.2%). The patient's treatment satisfaction was similar between the nurse-led versus physician-led teleconsultations (p=0.07). CONCLUSION: This study showed that a nurse-led telemedicine strategy is feasible to implement in a resource-constraint setting for triaging patients with CVD and reduces physician's burden.

The incidence and clinical impact of thrombotic events in hospitalized COVID-2019 illness.

BACKGROUND: Coronavirus disease-2019 (COVID-19) infection and thrombosis are of great clinical importance as this association has shown to increase mortality. We intend to estimate the incidence of thrombotic events (TE) and their impact on clinical outcomes in hospitalized COVID-19 patients. METHODS: This was an analytical cross-sectional study. The study population comprised of hospitalized COVID-19 patients between 1st March 2021 and 31st May 2021. The clinico-demographic data, thrombotic events, and clinical outcomes were collected from electronic health records. RESULTS: A total of 1274 patients were analyzed. The median age of the study population was 56 years (IQR: 44-66 years). The estimated incidence of TE was 5.8% (N.=74); 60.8% of these TE occurred in patients having severe/critical COVID-19 illness and 70.3% of TE occurred in patients in the intensive care unit. Venous events (3.9%) were common compared to arterial events(1.9%). On multivariate logistic regression analysis, total leukocyte count, C-reactive protein, and D-dimer level were found to be the independent predictors of having TE. Receiver operator curve revealed a cut-off point of 872.5 DDU µg/L for D-dimer level (sensitivity: 67.6% and specificity: 72.1%; P<0.001, area under curve 0.78) for predicting TE. Patients with TE had significantly higher mortality compared to those without TE (58.1% vs. 22.2%; P<0.001); and the presence of TE (OR=2.94; 95% CI:1.7-5.1, P<0.001) was found to be the independent predictor of mortality. CONCLUSIONS: The incidence of TE is high for hospitalized COVID-19 patients and it is even higher in severe/critical COVID illness. Its presence has shown to double the mortality compared to those without it.

An Optimized Machine Learning Model Accurately Predicts In-Hospital Outcomes at Admission to a Cardiac Unit.

Risk stratification at the time of hospital admission is of paramount significance in triaging the patients and providing timely care. In the present study, we aim at predicting multiple clinical outcomes using the data recorded during admission to a cardiac care unit via an optimized machine learning method. This study involves a total of 11,498 patients admitted to a cardiac care unit over two years. Patient demographics, admission type (emergency or outpatient), patient history, lab tests, and comorbidities were used to predict various outcomes. We employed a fully connected neural network architecture and optimized the models for various subsets of input features. Using 10-fold cross-validation, our optimized machine learning model predicted mortality with a mean area under the receiver operating characteristic curve (AUC) of 0.967 (95% confidence interval (CI): 0.963-0.972), heart failure AUC of 0.838 (CI: 0.825-0.851), ST-segment elevation myocardial infarction AUC of 0.832 (CI: 0.821-0.842), pulmonary embolism AUC of 0.802 (CI: 0.764-0.84), and estimated the duration of stay (DOS) with a mean absolute error of 2.543 days (CI: 2.499-2.586) of data with a mean and median DOS of 6.35 and 5.0 days, respectively. Further, we objectively quantified the importance of each feature and its correlation with the clinical assessment of the corresponding outcome. The proposed method accurately predicts various cardiac outcomes and can be used as a clinical decision support system to provide timely care and optimize hospital resources.

Changing microbiological profile and antimicrobial susceptibility of the isolates obtained from patients with infective endocarditis - The time to relook into the therapeutic guidelines.

The microbiological profile, associated risk factors and demographic characteristics of patients with IE has changed in the recent times. In the present study, the antibiotic susceptibility profile of 66 isolates (40 from IDU and 26 from non IDU) recovered over a period of three years from the patients with definitive diagnosis of IE along with their absolute minimum inhibitory concentrations (MIC-µg/ml) was determined as per CLSI, 2017 guidelines. Staphylococcus aureus was found to be the predominant pathogen associated with IE out of which 90.2% isolates were MRSA, although none of the isolates were found resistant to vancomycin, teicoplanin, daptomycin and linezolid. Pseudomonas aeruginosa isolates were 100% susceptible to carbapenams, however variable resistance was observed against other antimicrobials. All Enterococci were found to be 100% susceptible to linezolid and daptomycin, whereas vancomycin resistant enterococci phenotype was observed in 25% of the Enterococcal isolates. A noticeable difference in the antimicrobial susceptibility profile and their MICs were observed in the present study, as compared to published literature across the globe and within the country. However, no statistically significant difference (λ 2 test, p > 0.01)in the AST pattern of isolates from IDU vs. Non IDU was observed. After reviewing the local antibiogram it seems that we need to have our own regional guidelines, which may partially replace the currently prevailing AHA/ESC guidelines.

Managing patients of shock and acute kidney injury in tertiary care cardiac ICU: Experience with continuous renal replacement therapy.

BACKGROUND: Clinical experience on details of CRRT initiation and outcomes in cardiac intensive care unit (CICU) patients is not available from developing countries like India. This study shares the 5-year clinical experience of managing CICU patients requiring CRRT in a tertiary care cardiac center of North India. MATERIALS AND METHODS: Medical records of all CICU patients with acute kidney injury (AKI) managed by CRRT from October 2011 to September 2016 at tertiary referral center in North India were retrospectively reviewed. Multiple logistic regression analysis was used to identify predictors of post-CRRT mortality. RESULTS: A total of 630 patients received CRRT during the study period. Most commonly AKI developed in patients with acute coronary syndrome (30.2 %) with cardiogenic shock. 55.9 % of the CRRT patients were >60 years of age, and/or on multiple supports in ICU including, mechanical ventilation, high doses of inotropes & vasopressors and other cardiovascular support. Of those on CRRT, 130 (20.6 %) patients had died, 215 (34.1 %) were discharged and 285 (45.2 %) could not complete the desired course. Multivariate regression analysis showed independent association of mortality with high vasoactive-inotropic score, single CRRT cycle and low mean arterial pressure in CRRT patients. CONCLUSION: About 34.1 % of patients receiving CRRT were alive at discharge, emphasizing the feasibility and utility of CRRT as a promising modality in this population for improving outcomes.

Do anti-platelet drugs improve duration of continuous renal replacement therapy? A retrospective cohort study in cardiac ICU patients.

OBJECTIVE: The objective of this study was to investigate the impact of anti-platelet drug/s on duration of continuous renal replacement therapy (CRRT) in those patients where anti-coagulants were not used due to certain contraindications and in cases where patients were on anti-platelet drugs and were given anti-coagulant during CRRT. METHOD: This single-center, retrospective cohort study was conducted using the medical records patients treated with CRRT in the cardiac ICU of the inpatient urban facility, located in North India. Data was collected from only those patients who received CRRT for the duration of at least 12 h. Patient's in NAC group were not on any anti-platelet/s and did not receive anti-coagulant during CRRT. AC and AP group patients received anti-coagulant alone or were already on anti-platelet/s and did not receive anti-coagulant respectively while ACAP group patients were on anti-platelet drug/s and also received anti-coagulant during CRRT. RESULT: Patients in AC, AP, or ACAP group showed significantly (p < 0.001) higher CRRT filter life compared to NAC group. The median CRRT filter life was significantly higher in the ACAP group compared to AC (p < 0.05) and AP (p < 0.001) groups. CONCLUSION: This study indicates that systemic anti-platelet therapy can provide additional support in critical patients undergoing CRRT even with or without anti-coagulant therapy. However, the increase in CRRT filter life was more profound in patients who were on anti-platelet/s and also received anti-coagulant drug/s during CRRT.

Real world data on clinical profile, management and outcomes of venous thromboembolism from a tertiary care centre in India.

OBJECTIVES: Venous thromboembolism (VTE) is a major cause of mortality and morbidity worldwide. This study describes a real-world scenario of VTE presenting to a tertiary care hospital in India. METHODS: All patients presenting with acute VTE or associated complications from January 2017 to January 2020 were included in the study. RESULTS: A total of 330 patient admissions related to VTE were included over 3 years, of which 303 had an acute episode of VTE. The median age was 50 years (IQR 38-64); 30% of patients were younger than 40 years of age. Only 24% of patients had provoked VTE with recent surgery (56%) and malignancy (16%) being the commonest risk factors. VTE manifested as isolated DVT (56%), isolated pulmonary embolism (PE; 19.1%), combined DVT/PE (22.4%), and upper limb DVT (2.3%). Patients with PE (n = 126) were classified as low-risk (15%), intermediate-risk (55%) and high-risk (29%). Reperfusion therapy was performed for 15.7% of patients with intermediate-risk and 75.6% with high-risk PE. In-hospital mortality for the entire cohort was 8.9%; 35% for high-risk PE and 11% for intermediate-risk PE. On multivariate analysis, the presence of active malignancy (OR = 5.8; 95% CI: 1.1-30.8, p = 0.038) and high-risk PE (OR = 4.8; 95% CI: 1.6-14.9, p = 0.006) were found to be independent predictors of mortality. CONCLUSION: Our data provides real-world perspectives on the demographic sand management of patients presenting with acute VTE in a referral hospital setting. We observed relatively high mortality for intermediate-risk PE, necessitating better subclassification of this group to identify candidates for more aggressive approaches.

Image of the month: An unusual cause of cough, stridor and dyspnoea: A giant aortic arch aneurysm.

A 78-year-old man with hypertension presented with dry cough and gradually progressive dyspnoea for 3 months. The patient had an audible stridor. Cardiovascular examination was unremarkable. Respiratory system examination revealed both inspiratory and expiratory grunting sound. Laboratory investigations were normal. Electrocardiography showed sinus rhythm with left ventricular hypertrophy (LVH). Chest X-ray showed superior mediastinal widening. Transthoracic echocardiography showed preserved LV functions and dilated aortic arch. Contrast-enhanced computed tomography of the thorax showed a huge aortic arch aneurysm compressing the adjacent trachea. The patient was planned for hybrid aortic arch repair but the patient refused and was discharged on antihypertensive, antiplatelet and statin therapy. The patient continued to have limiting cough, dyspnoea and stridor for 4 months of follow-up until he suddenly died while at home. This case highlights an unusual presentation of a potentially lethal disease. Evaluation of patients presenting with cough and dyspnoea should not be restricted to respiratory diseases. The critical observations made from history.

A Simple Effective Method for Frailty in Heart Failure with Impact on Clinical Outcomes in North Indian Population.

Introduction and objectives: Frailty has been studied extensively in elderly population as a predictor and prognostic marker for morbidity and mortality. Frailty is being increasingly recognized as a distinct pathophysiological condition which plays a major role in outcomes of various disease states including heart failure. Our aim was to study the prevalence of frailty in heart failure and see its prognostic significance in such patients. Methods: This was a prospective study conducted in an out-patient HF clinic. All consecutive patients with HF, ≥25 years age, with LVEF<40% were included. All patients were asked a simple frailty questionnaire. Hand-dynamometer was used to assess handgrip strength in kilograms and were classified as frail, pre-frail or non-frail. The primary end point was cardiovascular mortality and hospitalization, and secondary end-point was composite of all cause mortality, hospitalization, device implantation and documented arrythmia. Results: 210 patients were studied for clinical outcomes. Mean age was 60.59 ± 11.55 years with 15% patients aged less than 50 years. Mean LVEF was 30.24 ± 6.8%. Handgrip strength was poor in the frail vs non/pre-frail patients (p = 0.001) with a strength >16.95 kg having sensitivity of 72% and specificity of 63% for the prediction of survival. Frailty was an independent predictor of mortality with higher mortality and re-hospitalization in frail population (p = 0.001). Hazard for mortality or hospitalization was 4.7 fold in frail population. Conclusion: Frailty is associated with a significant morbidity and mortality in heart failure. A simple bedside hand-dynamometer may aid as a frailty screening tool in these patients and help in planning treatment strategies.
