Study of pattern & distribution of adverse drug reactions in acute coronary syndrome patients in a tertiary care hospital.

Background & objectives: With the availability of a wide range of drugs to treat patients with acute coronary syndrome (ACS), adverse drug reactions (ADRs) have become inevitable in clinical practice. Thorough knowledge of such reactions is essential for the treating physician for optimal treatment and better outcomes. There are many scales to define, measure and assess the ADRs, but there is a dearth of data available on such drug reactions among ACS patients. Hence, this study attempted to analyze the pattern, causality, severity, predictability and preventability of ADRs in ACS patients. All the ADRs reported during the study period were analyzed for causality by the World Health Organization-Uppsala Monitoring Centre (WHO-UMC), Naranjo's and Karch and Lasagna scales; severity by modified Hartwig and Siegel scale; predictability by Rawlins and Thompson criterion and preventability by Schumock and Thornton scale. Methods: A single-centre, record-based analysis for the occurrence of ADRs was done among ACS patients admitted to the department of Cardiology between January and October 2017. Demographic data, comorbid conditions, reported ADRs and ADR assessment details were noted from the hospital case records and ADR monitoring centre (AMC) records. The data were analyzed and presented in a descriptive manner using percentages, mean and standard deviation. The Pearson's chi-squared test was used to ascertain the significance of the association between different groups. Results: Out of 324 patients under evaluation, 67 had developed one or more ADRs. There were 30 different types of ADRs reported, headache being the most common. Among the drugs, heparin was the most common factor, causing 27 per cent of ADRs. Definite causality of a suspected drug causing ADRs was seen in 11.9 (n=8), nine (n=6) and 7.5 (n=5) per cent cases as per WHO-UMC, Naranjo (Naranjo algorithm) and Karch and Lasagna scales, respectively. In the severity of ADRs, the most severe reactions according to the modified Hartwig-Siegel scale (level 4a in our study) were seen in 17.5 (n=12) per cent of patients, and the rest were either level 2 or 3 reactions. Nearly 92.5 (n=62) per cent of reactions were predictable according to the Rawlins and Thompson criterion. Application of the modified Schumock-Thornton scale showed that 22.4 per cent of ACS patients had preventable reactions, and the rest were not preventable. Interpretation & conclusions: The study results suggest that ADRs are relatively common among ACS patients. Most of these can be identified and assessed for causality, severity, predictability and preventability using various available scales. Diligent pharmacovigilance for identifying and assessing ADRs may help manage and mitigate morbidity associated with these in high-risk ACS patients.

Large right-sided pneumothorax with Takotsubo cardiomyopathy.

Patients with left-sided pneumothorax presenting with electrocardiogram (ECG) changes resembling acute coronary syndrome (ACS) have been reported in the literature. Takotsubo cardiomyopathy (TCM) occurs predominantly in post-menopausal women with underlying intense emotional or physical stress. However, as this case report shows, it can complicate any acute illness leading to intense stress. We report a rare combination of ECG changes mimicking ACS in a man with a large right-sided pneumothorax and TCM.

Pseudocoarctation of the Arch and the Abdominal Aorta: A Review.

Pseudocoarctaion of the aorta is a rare congenital anomaly occurring in isolation or with other congenital heart diseases. The anatomical basis of the condition is linked to an elongated, redundant aorta which may affect the arch, or the abdominal aorta rarely giving rise to kink and buckling without causing any significant functional stenosis. It should be carefully differentiated from the common true coarctation of the aorta. No clinical features are specific to pseudo coarctation and are often diagnosed incidentally. Although asymptomatic in the majority, few patients can have nonspecific symptoms and complications due to aneurysm formation, dissection, or rupture of the aorta. Hence Pseudocoarctaion should be closely followed for the onset of symptoms or possible complications. Without recommendations, no specific therapy is indicated in asymptomatic patients, although symptoms and complications warrant definitive treatment. As the natural history of the disease is unknown, the condition, when diagnosed, should be closely followed up for the occurrence of any complications. This article reports a pseudo aortic coarctation involving the arch and a brief literature review of this rare congenital anomaly.

Rare complication of doxorubicin-induced complete heart block in a patient with Hodgkin's lymphoma: a case report.

Anthracyclines are associated with cardiotoxic manifestations that are mainly dose-dependent, with onset varying from a few days to many years after stopping treatment. Frequent monitoring for toxic manifestations, early detection, cessation of anthracycline use and appropriate treatment is the key to preventing morbidity and mortality. Complete heart block with doxorubicin use in Hodgkin's lymphoma is rarely reported, and is a severe toxic manifestation necessitating withdrawal or changing of regimen to etoposide + bleomycin + vinblastine + dacarbazine (EBVD), as in this case.

Bridging Treatment Implementation Gaps in Patients With Heart Failure: JACC Focus Seminar 2/3.

Heart failure (HF) is a leading cause of death and disability in older adults. Despite decades of high-quality evidence to support their use, guideline-directed medical therapies (GDMTs) that reduce death and disease burden in HF have been suboptimally implemented. Approaches to closing care gaps have focused largely on strategies proven to be ineffective, whilst effective interventions shown to improve GDMT uptake have not been instituted. This review synthesizes implementation interventions that increase the uptake of GDMT, discusses barriers and facilitators of implementation, summarizes conceptual frameworks in implementation science that could improve knowledge uptake, and offers suggestions for trial design that could better facilitate end-of-trial implementation. We propose an evidence-to-care conceptual model that could foster the simultaneous generation of evidence and long-term implementation. By adopting principles of implementation science, policymakers, researchers, and clinicians can help reduce the burden of HF on patients and health care systems worldwide.

The Emergence of Artificial Intelligence in Cardiology: Current and Future Applications.

In this article, we review the literature on artificial intelligence and its utility in cardiology. We provide a detailed description of concepts of artificial intelligence tools like machine learning, deep learning, and cognitive computing. This review discusses the current evidence, application, prospects, and limitations of artificial intelligence in cardiology.

The COVID-19 Pandemic Surge and Impact on Rheumatic Valvular Heart Disease Patient Care.

The COVID-19 crisis has surged worldwide, putting immense stress on the health care services, leading to institutions deferring elective procedures and struggling to triage the emergency care of cardiac patients. This has affected the management of the rheumatic valvular heart disease patients especially, in developing countries, potentially placing these patients at enormous risk for complications like congestive cardiac failure, stroke and death. This article explores the COVID-19 pandemic and its impact on rheumatic valvular heart disease patient care. We try to provide a framework that addresses the procedural considerations of interventions like percutaneous transluminal mitral commissurotomy (PTMC), mitral and aortic valve surgeries. This article also highlights the implications for the outpatient valve clinic, and safety issues of the patient and health care workers during this ongoing pandemic.

Disseminated Actinomycosis Presenting as Chronic Right-Heart Failure Due to Right Ventricular and Pericardial Infiltration.

Actinomycosis is an indolent, slowly progressive bacterial infection prevalent in tropical countries, commonly affecting cervicofacial, thoracic, abdominal, or pelvic regions. With early diagnosis and appropriate therapy, the prognosis is excellent. However, late presentation and widespread dissemination can be fatal. This paper reports a rare case of disseminated actinomycosis with fatal cardiac involvement. (Level of Difficulty: Intermediate.).

COVID-19 Pandemic and the Impact on the Cardiovascular Disease Patient Care.

The COVID-19 pandemic has emerged as a serious global threat causing a large number of fatalities and putting enormous strain on the health care resources across the world. This has resulted in preferentially triaging the coronavirus infected patients and placing others, especially cardiovascular patients at increased risk for adverse complications. The effective management of cardiac patients in the hospital environment during this COVID-19 pandemic has emerged as a real challenge. We try to address this issue and also highlight the interplay between COVID-19 and cardiovascular diseases. We hereby review the available literature and emerging guidelines about cardiovascular implications related to COVID-19 which will have a bearing on the patient care, health care professionals and cardiac centres.

Analysis of solid tumor mutation profiles in liquid biopsy.

Liquid biopsy is increasingly gaining traction as an alternative to invasive solid tumor biopsies for prognosis, treatment decisions, and disease monitoring. Matched tumor-plasma samples were collected from 180 patients across different cancers with >90% of the samples below Stage IIIB. Tumors were profiled using next-generation sequencing (NGS) or quantitative PCR (qPCR), and the mutation status was queried in the matched plasma using digital platforms such as droplet digital PCR (ddCPR) or NGS for concordance. Tumor-plasma concordance of 82% and 32% was observed in advanced (Stage IIB and above) and early (Stage I to Stage IIA) stage samples, respectively. Interestingly, the overall survival outcomes correlated to presurgical/at-biopsy ctDNA levels. Baseline ctDNA stratified patients into three categories: (a) high ctDNA correlated with poor survival outcome, (b) undetectable ctDNA with good outcome, and (c) low ctDNA whose outcome was ambiguous. ctDNA could be a powerful tool for therapy decisions and patient management in a large number of cancers across a variety of stages.

Renal Metastasis and Dual (18F-Fluorodeoxyglucose and 131I) Avid Skeletal Metastasis in a Patient with Papillary Thyroid Cancer.

Differentiated thyroid carcinoma (DTC) though usually behaves in an indolent manner, can have unusual metastatic presentation. Initial presentation of metastatic disease has been reported in 1-12% of DTC being less frequent in papillary (~2%) than in follicular (~10%) thyroid carcinoma. Renal metastasis from DTC is very rare. To our knowledge, only about 30 cases have been reported in the English literature to date. To make clinicians aware that management of such high-risk thyroid cancer frequently requires novel multimodality imaging and therapeutic techniques. A 72-year-old female is described who presented with abdominal pain and bilateral lower limbs swelling. Initial contrast enhanced computed tomography (CT) scan of abdomen showed a well-encapsulated mass in the upper pole of right kidney favoring a renal cell carcinoma. Postright sided radical nephrectomy, histopathology, and immunohistochemistry reports suggested metastatic deposits from thyroid malignancy. 18F-fluorodeoxyglucose (FDG) positron emission tomography-CT demonstrated hypermetabolic nodule in the left lobe of thyroid and a lytic lesion involving left acetabulum suggestive of skeletal metastasis. Subsequently, ultrasound-guided fine needle aspiration cytology of the thyroid nodules in bilateral lobes confirmed thyroid malignancy (Bethesda 6/6). Total thyroidectomy revealed papillary thyroid cancer (PTC) (follicular variant-PTC [FV-PTC]). After surgery, 131I-whole body scan showed iodine avid lytic lesion in the left acetabulum. The present case is a rare scenario of a renal metastasis as the presenting feature of an FV-PTC. Dual avidity in metastatic thyroid cancers (iodine and FDG) is rare and based on the degree of dedifferentiation of the DTC.

Percutaneous mitral balloon valvotomy in a case of situs inversus dextrocardia with severe rheumatic mitral stenosis.

The efficacy, safety and applicability of Inoue balloon technique for BMV are clearly established worldwide in selected subset of patients with rheumatic mitral stenosis (MS). However, in altered cardiac anatomy it offers technical challenges. Distorted cardiac anatomy and cardiac malpositions considerably increase the complications involved in interatrial septal puncture and left ventricular entry during BMV. There are only a few reports worldwide on successful BMV in altered cardiac anatomy using the standard Inoue technique. Here we describe a case of a 27-year-old female with situs inversus and dextrocardia, where BMV was successfully performed with a few modifications of the standard Inoue technique previously described in similar patients.
