Edema India: Executive Summary of Screening, Diagnosis, and Management of Edema.

The management of edema requires a systematic approach to screening, diagnosis, and treatment, with an essential initial assessment to differentiate between generalized and localized edema. The Association of Physicians of India (API) aimed to develop the first Indian Edema Consensus (Edema India), offering tailored recommendations for screening, diagnosing, and managing edema based on the insights from the expert panel. The panel suggested when evaluating edema symptoms, important factors to consider include the patient's current illness, medical history, risk factors, family history, and medications. Key diagnostic investigations for edema include complete blood count, cardiovascular imaging and markers, deep vein thrombosis (DVT) assessment, along with renal, hepatic, and thyroid function tests. Edema management involves a combination of pharmacologic and nonpharmacologic interventions, including limb elevation, physiotherapy, compression therapy, fluid removal, diuretics (loop diuretics: first-line therapy), and a sodium-restricted diet. The panel believed that educating patients could foster a preventive mindset, helping to prevent the worsening of edema.

Myriads of Arrythmias and Cardiac Arrest as Modes of Presentation in Takotsubo Cardiomyopathy.

Takatsubo cardiomyopathy (TC) is a relative novel condition that has been increasingly reported. Studies have shown the incidence on TC to be 1-2 % of all patients presenting with acute coronary syndrome which amounts a large subset of patients. Various arrhythmias have been reported with TC, varying from benign QTc prolongation to serious life threatening ventricular arrhythmias. We present two cases of TC with myriad of ventricular arrhythmias.

Acute myocardial infarction--an unusual presentation of non-specific aortoarteritis.

A 42 year old man presented with classical presentation of Acute ST elevation MI of 2 hours duration. His CAG revealed a spared LMCA with a totally occluded LAD in proximal segment, for which he underwent a successful PAMI with DES to LAD. 2 days later he developed high grade fever, elevated inflammatory markers (ESR/CRP) with a dull aching pain in root of neck. On evaluation of brachiocephalic vessels, CT Aortogram suggested a diagnosis of acute onset Non-Specific Aortoarteritis. Nonspecific Aortoarteritis in young males is an uncommon presentation, though associated coronary artery involvement is known, but its presentation as an Acute MI is a rare phenomenon.

Carbimazole-associated Pancreatitis: Report From Western India.

Pancreatitis is a very rare complication of methimazole and carbimazole therapy. We describe a case of possible carbimazole-associated pancreatitis. A 41-year-old Asian man (with no comorbidities) reported to the hospital with atrial fibrillation and a fast ventricular rate. He was diagnosed with hyperthyroidism due to Graves disease. His rhythm was reverted with amiodarone, and carbimazole was initiated at 15 mg daily for the medical management of Graves disease. Fifteen days later, he presented with acute severe abdominal pain and vomiting with elevated serum amylase 387 U/L (reference range, 28-100 U/L) and lipase levels 206 U/L (reference range, 13-60 U/L). Magnetic resonance imaging showed a bulky pancreas with extensive extrapancreatic fat stranding suggestive of acute pancreatitis. Considering the possibility of carbimazole-related pancreatitis, the drug was withheld. He was managed conservatively, and his pancreatic enzymes normalized within 1 week. The observation suggests that the pancreatitis was a consequence of the therapy with carbimazole. Although it is a rare occurrence, patients taking carbimazole who report abdominal discomfort and vomiting should be evaluated for pancreatitis.

Aspirin Monotherapy vs No Antiplatelet Therapy in Stable Patients With Coronary Stents Undergoing Low-to-Intermediate Risk Noncardiac Surgery.

BACKGROUND: Current guidelines recommend the perioperative continuation of aspirin in patients with coronary drug-eluting stents (DES) undergoing noncardiac surgery. However, supporting evidence is limited. OBJECTIVES: This study aimed to compare continuing aspirin monotherapy vs temporarily holding all antiplatelet therapy before noncardiac surgery in patients with previous DES implantation. METHODS: We randomly assigned patients who had received a DES >1 year previously and were undergoing elective noncardiac surgery either to continue aspirin or to discontinue all antiplatelet agents 5 days before noncardiac surgery. Antiplatelet therapy was recommended to be resumed no later than 48 hours after surgery, unless contraindicated. The primary outcome was a composite of death from any cause, myocardial infarction, stent thrombosis, or stroke between 5 days before and 30 days after noncardiac surgery. RESULTS: A total of 1,010 patients underwent randomization. Among 926 patients in the modified intention-to-treat population (462 patients in aspirin monotherapy group and 464 patients in the no-antiplatelet therapy group), the primary composite outcome occurred in 3 patients (0.6%) in the aspirin monotherapy group and 4 patients (0.9%) in the no antiplatelet group (difference, -0.2 percentage points; 95% CI: -1.3 to 0.9; P > 0.99). There was no stent thrombosis in either group. The incidence of major bleeding did not differ significantly between groups (6.5% vs 5.2%; P = 0.39), whereas minor bleeding was significantly more frequent in the aspirin group (14.9% vs 10.1%; P = 0.027). CONCLUSIONS: Among patients undergoing low-to-intermediate risk noncardiac surgery >1 year after stent implantation primarily with a DES, in the setting of lower-than-expected event rates, we failed to identify a significant difference between perioperative aspirin monotherapy and no antiplatelet therapy with respect to ischemic outcomes or major bleeding.

Rotastenting in an anomalously arising right coronary artery after an ugly dissection.

Rotational atherectomy is contraindicated in dissected coronary arteries since it can lead to progression of the dissection or perforation. In our case, the right coronary artery (RCA) arose anomalously from the left coronary sinus. The lesion in the RCA was an undilatable calcified one. There was a dissection in the RCA due to high pressure balloon dilatation. Since the patient was hemodynamically unstable and there were no options besides rotablation, we proceeded with caution. Rotablation and stenting were successfully done. Our case report highlights the importance of the need for good guide catheter support even in the presence of anomalously arising arteries and the rotablation option for unyielding calcified coronary lesions, even in the setting of a dissection.

Left atrial spindle cell sarcoma - case report.

Primary spindle cell sarcoma of the left atrium is an extremely rare tumour. Surgical excision is the mainstay of treatment since it responds poorly to chemotherapy or radiotherapy. In spite of all the treatment, the prognosis remains poor due to inadvertent delay in diagnosis, few therapeutic options and propensity to metastasize. We present a 47-year-old male who underwent a surgical excision of a left atrial mass in February 2010. It was proved to be a high-grade spindle cell sarcoma on histopathology. He presented again in October 2010 with recurrence of the tumour for which he was re-operated. However, the tumour recurred again within one month, to which the patient succumbed.

Clinical characteristics and 30-day outcomes in patients with acute decompensated heart failure: Results from Indian College of Cardiology National Heart Failure Registry (ICCNHFR).

BACKGROUND: Acute decompensated heart failure (ADHF) is a challenging medical emergency with high mortality and its prevalence is increasing in India. There is paucity of data on ADHF in the country. METHODS: Indian College of Cardiology National Heart Failure Registry (ICCNHFR) is an on-going observational registry on ADHF contributed by 22 hospitals across India; and we present the in-hospital and 30-day outcomes of ADHF patients enrolled from August 2018 to July 2019. Major objective included capturing demographics, comorbid conditions, aetiology, prescription patterns and assessing clinical outcomes. RESULTS: Of 5269 patients (mean age: 61.90 ± 13.85 years) enrolled in this study, males were predominant (67.09%). Mean duration of hospitalization was 5.74 ± 4.74 days. Ischemic heart disease was the most common (75.44%) aetiology. Abnormal electrocardiogram readings were found in most patients (89.86%). LVEF of ˂40% was found in 68.29% of patients. In-hospital mortality rates were 6.98%. The 30-day cumulative mortality was 12.35% and 30-day rehospitalization rate was 7.98%. At discharge, all guideline-based medical therapy (GDMT) were prescribed only to 24.99% of patients and 23.72% adhered to the prescription until 30 days. Older age, high serum creatinine levels and poor LVEF contributed to high mortality and rehospitalization. CONCLUSION: Patients with ADHF were younger and predominantly males. Usage of GDMT in ADHF patients was low (24.99%) and the in-hospital mortality was high. Older age, high serum creatinine levels, poor LVEF contributed for 30-day mortality and rehospitalization. This data on ADHF, could help in developing strategies to improve outcomes for HF patients in India.

MIBG negative pheochromocytoma.

We present a case of a left sided pheochromocytoma, who had normal levels of 24 urinary vanilylmandelic acid and a normal MIBG scan. The diagnosis was confirmed on histopathology of the adrenal gland.

Diagnostic utility and safety of intracoronary nicorandil as a hyperemic agent for the measurement of fractional flow reserve.

We investigated the diagnostic utility and safety of intracoronary bolus administration of nicorandil compared with intravenous administration of adenosine for evaluating FFR in patients with intermediate (40-70%) coronary stenosis. The FFR values obtained with nicorandil and adenosine showed linear relationship. This correlation is statistically significant with regression coefficient of 0.932 (R2 = 0.834, p < 0.001). The side effects such as bronchospasm, hypotension, and bradycardia were significantly higher after administration of adenosine compared to nicorandil (20% vs. 1.66%, p = 0.001). Intracoronary use of nicorandil seems to be promising in offering the advantages of lesser side effects, similar efficacy, and lesser cost as compared to adenosine.

Are Proteinopathy and Oxidative Stress Two Sides of the Same Coin?

Parkinson's disease, like other neurodegenerative diseases, exhibits two common features: Proteinopathy and oxidative stress, leading to protein aggregation and mitochondrial damage respectively. Because both protein aggregates and dysfunctional mitochondria are eliminated by autophagy, we suggest that inadequate clearance may couple the two phenomena. If a neuron's autophagy machinery is overwhelmed, whether by excessive oxidative stress or by excessive protein aggregation, protein aggregates and dysfunctional mitochondria will both accumulate. Parkinson's disease may provide a unique window into this because there is evidence that both sides contribute. Mutations amplifying the aggregation of α-synuclein are associated with Parkinson's disease. Likewise, mutations in Parkin and PINK1, proteins involved in mitophagy, suggest that impaired mitochondrial clearance is also a contributing factor. Many have suggested that dopamine oxidation products lead to oxidative stress accounting for the dopaminergic selectivity of the disease. We have presented evidence for the specific involvement of hypochlorite-oxidized cysteinyl-dopamine (HOCD), a redox-cycling benzothiazine derivative. While toxins like 6-hydroxydopamine and 1-methyl-4-phenyl pyridinium (MPP+) have been used to study mitochondrial involvement in Parkinson's disease, HOCD may provide a more physiologically relevant approach. Understanding the role of mitochondrial dysfunction and oxidative stress in Parkinson's disease and their relation to α-synuclein proteinopathy is important to gain a full picture of the cause, especially for the great majority of cases which are idiopathic.

Predictors of success in percutaneous Coronary intervention for chronic total occlusion.

We performed a retrospective analysis of 146 chronic total occlusion CTO patients to evaluate the antecedents of success and failure in CTO - Percutaneous Coronary Intervention (PCI) in Indian patients. The study aimed to identify the technical success rate, analyse immediate patient outcomes, and understand the factors impacting the successful outcomes. Our results showed that J-CTO (Multicenter CTO Registry of Japan) scores correlate well with the success rates of CTO-PCI and two most important factors deciding failure are lesion length more than 20 mm and lesions with calcification. Most important step to success of CTO is wiring, once wire crosses the segment, success rates of the procedure is around 97%. The wire escalation strategy has to be modified once the initial soft (polymer) wire fails, it's reasonable to use high tip load wire like conquest pro without the use of intermediate wires (except in presence of tortuosity). At 1 year follow up of these patients, there was a statistically significant drop in angina class and major adverse cardiac event rates in the successful CTO group.

Hypochlorite converts cysteinyl-dopamine into a cytotoxic product: A possible factor in Parkinson's Disease.

The dopamine oxidation product cysteinyl-dopamine has attracted attention as a contributor to the death of dopaminergic neurons in Parkinson's disease. Treatment of cysteinyl-dopamine with hypochlorite yields an even more cytotoxic product. This product has potent redox-cycling activity and initiates production of superoxide in PC12 cells. Taurine, which scavenges hypochlorite, protects PC12 cells from cysteinyl-dopamine but not from the hypochlorite product, suggesting that the product, not cysteinyl-dopamine itself, is toxic. Furthermore, rotenone, which enhances expression of the hypochlorite-producing enzyme myeloperoxidase, increases the cytotoxicity of cysteinyl-dopamine but not of the hypochlorite product. This suggests that dopamine oxidation to cysteinyl-dopamine followed by hypochlorite-dependent conversion to a cytotoxic redox-cycling product leads to the generation of reactive oxygen species and oxidative stress and may contribute to the death of dopaminergic neurons.

Aortic dissection one year after aortic valve replacement.

Acute aortic dissection after aortic valve replacement is rare. A 57-year-old man presented with an acute type A aortic dissection 1 year after aortic valve replacement, which originated from the previous aortotomy site. He underwent a Bentall procedure. Postoperatively, he developed complete heart block requiring permanent pacemaker implantation. During aortic valve replacement, risk factors for aortic dissection (diameter of the aorta and fragility and thinness of the aortic wall) should be assessed. Prophylactic aortic root replacement should be undertaken if the aortic root is more than 45 mm in diameter.
