Age-stratified cutpoints for aminoterminal pro-brain natriuretic peptide (NT-pro-BNP) concentrations are diagnostic in 83% of all subjects with acute dyspnea. This study analyzed subjects with NT-pro-BNP concentrations between the "rule-out" and "rule-in" cutpoints, the so-called natriuretic peptide gray zone. NT-pro-BNP concentrations, clinical characteristics, and 60-day mortality were studied in 1,256 acutely dyspneic patients from an international multicenter study. Of all subjects, 215 had gray-zone NT-pro-BNP concentrations, 116 of whom (54%) were diagnosed with heart failure (HF). Among these subjects, patients with HF were more likely to be older, to have a history of HF, to be in atrial fibrillation, and to have elevated troponin T concentrations compared with those without HF. In multivariate analysis, the use of loop diuretics on presentation (odds ratio [OR] 3.99, 95% confidence interval [CI] 1.58 to 10.1, p = 0.003), paroxysmal nocturnal dyspnea (OR 4.50, 95% CI 1.31 to 15.4, p = 0.02), jugular venous distention (OR 3.05, 95% CI = 1.06 to 8.79, p = 0.04), and the absence of cough (OR 0.18, 95% CI 0.06 to 0.52, p = 0.001) were associated with a diagnosis of acute HF in gray-zone patients. Subjects with HF and diagnostically elevated NT-pro-BNP concentrations had the highest mortality rates, subjects without HF and NT-pro-BNP concentrations < 300 ng/L had the lowest mortality rates, and subjects with gray-zone NT-pro-BNP had intermediate outcomes, irrespective of their final diagnoses. Adding specific clinical information to NT-pro-BNP improves diagnostic accuracy in subjects with intermediate NT-pro-BNP concentrations. Mortality rates in subjects with intermediate NT-pro-BNP concentrations are lower than in those with NT-pro-BNP concentrations diagnostic for HF but are higher than in subjects with NT-pro-BNP concentrations less than the gray zone.

Kounis syndrome is a clinical condition due to hypersensitivity that culminates into acute coronary syndrome (ACS) which can be fatal. A 36-year-old male with no conventional coronary risk factors presented elsewhere with a history of fever for 4 days, cough with expectoration, diarrhea and was treated with cephalosporin (Inj. Cefotaxime as an infusion) along with analgesics. He experienced generalized itching 5 minutes after cefotaxime infusion followed by sweating, headache, chest pain with facial and periorbital swelling for which he was rushed to our hospital. On examination he was afebrile with a low blood pressure. Electrocardiogram taken at an outside hospital revealed incomplete right bundle branch block and ST depression V3-V5. Investigations showed increase in troponin T. He was managed with anti-histamines and standard protocol for treatment of ACS. Coronary angiogram revealed normal coronaries. The patient improved symptomatically with treatment and was discharged on an anti-platelet, nitrate and a statin.

Takotsubo cardiomyopathy (TCM) is a unique type of cardiomyopathy characterised by left ventricular systolic dysfunction in association with stressful conditions. Patients with this condition usually present with chest pain and dyspnoea, and the presentation can mimic acute coronary syndrome. We present a case of a woman aged 58 years who presented with progressive dyspnoea and cough. Her initial evaluation was suggestive of acute myocardial infarction with elevated serum troponin T and ST segment elevation. Her chest radiograph showed a large right-sided pneumothorax, which was treated with chest tube insertion. Coronary angiography and echocardiogram did not show any evidence of obstructive coronary artery disease but did show a large area of akinesis consistent with TCM. The patient was managed medically with supportive care. Her pneumothorax resolved, and her follow-up echocardiogram also showed improvement. The association between pneumothorax and TCM is rare, and only four other cases have been reported so far in the English literature.

Myopericarditis remains a prominent infectious inflammatory disorder throughout a patient's lifetime. Moreover, viral pathogens have been proven to be the leading contributors to myopericarditis in the pediatric and adult populations. Despite the current comprehensive knowledge of myocardial injury in viral and post-viral myopericarditis, the cellular and molecular mechanisms of SARS-CoV-2-induced myopericarditis are poorly understood. This report presents a case of coronavirus (COVID-19) fulminant myopericarditis and acute respiratory distress syndrome (ARDS) in a middle-aged male patient: a 51-year-old man with a history of hypertension who arrived to the emergency department with a dry cough, fatigue, dyspnea, and a fever. A real-time reverse transcriptase-polymerase chain reaction (RT-PCR) assay confirmed a diagnosis of COVID-19 infection, resulting in the patient's admission to the airborne isolation unit for clinical observation. When his condition began to deteriorate, the patient was transferred to the cardiac care unit after electrocardiography detected cardiac injury, demonstrating diffuse ST-segment elevation. Laboratory evaluations revealed elevated troponin T and BNP, with an echocardiogram indicating global left ventricular hypokinesia and a reduced ejection fraction. The patient was treated with hydroxychloroquine, azithromycin, dobutamine, remdesivir, and ventilatory support. This specific case highlights the severity and complications that may arise as a direct result of COVID-19 infection.
