ABSTRACT
Experience with angiotensin-receptor neprilysin inhibitors (ARNI) in oncologic patients with heart failure (HF) is limited. We report a case of ARNI started as first-choice therapy in a patient with relapsing hairy cell leukaemia (HCL) and HF with depressed left ventricular ejection fraction (LVEF). A middle-aged male, previously treated with rituximab for HCL, was scheduled for cardiologic screening before starting a new antineoplastic therapy for cancer relapse. The patient had symptomatic HF with reduced LVEF and high NT-proBNP levels. In this patient, early ARNI treatment was well tolerated and produced a rapid and durable improvement of symptoms, LVEF and NT-proBNP levels. Consequently, the oncologic team could start an experimental treatment with obinutuzumab, with complete HCL remission. In conclusion, in this patient with HCL and HF, ARNI therapy was safe and effective, contributing to undelayed cancer treatment.
ABSTRACT
SARS-CoV-2 infection is associated with an increased risk of venous thromboembolism (VTE), which is common during active illness but unusual in milder cases and after healing. We describe a case of bilateral acute pulmonary embolism occurring 3 months after recovery from a paucisymptomatic SARS-CoV-2 infection. The only VTE risk factor demonstrable was a history of previous SARS-CoV-2 infection, with laboratory signs of residual low-grade inflammation. Clinicians should be aware of VTE as a potential cause of sudden dyspnoea after COVID-19 resolution, especially in the presence of persistent systemic inflammation. LEARNING POINTS: Venous thromboembolism may occur after COVID-19, even in milder SARS-CoV-2 infections and late after coronavirus clearance.Laboratory signs of systemic inflammation are clues for suspecting venous thromboembolism as a cause of sudden dyspnoea in patients with low risk scores for pulmonary embolism but with previous COVID-19 infection.
ABSTRACT
OBJECTIVES: We tested the noninferiority of a fast-track rule-out protocol for the diagnosis of non-ST-segment elevation myocardial infarction vs noncoronary chest pain based on the single-sampling combined assessment of medium-sensitivity cardiac troponin I and ultra-sensitive copeptin compared with the serial assessment of medium-sensitivity cardiac troponin I. METHODS: Ultra-sensitive copeptin and medium-sensitivity cardiac troponin I levels were measured at presentation in 196 consecutive patients admitted to the emergency department for acute nontraumatic chest pain within 6 hours from symptoms onset and without ST-segment elevation on a 12-lead electrocardiogram. The diagnostic performance for non-ST-segment elevation myocardial infarction diagnosis of the dual-marker single-sampling strategy with medium-sensitivity cardiac troponin I and ultra-sensitive copeptin on admission was compared with that of the serial 0- and 3-hour medium-sensitivity cardiac troponin I sampling in reference to the adjudicated postdischarge diagnosis, using both the comparison of area under the curve (AUC) receiver operating characteristic and the McNemar chi-square test. RESULTS: The diagnosis of non-ST-segment elevation myocardial infarction was adjudicated in 29 patients (14.8%). The combination of medium-sensitivity cardiac troponin I and ultra-sensitive copeptin generated an AUC of 0.87 (95% confidence interval, 0.82-0.91), which was noninferior with respect to the 3-hour interval medium-sensitivity cardiac troponin I serial sampling (P = .194 for AUC difference). The combination of medium-sensitivity cardiac troponin I and ultra-sensitive copeptin also yielded a numerically higher diagnostic sensitivity (100% vs 89.7%; P = not significant). CONCLUSIONS: A single-sampling strategy of combined ultra-sensitive copeptin and medium-sensitivity cardiac troponin I is noninferior to a 0- and 3-hour serial medium-sensitivity cardiac troponin I sampling in ruling out non-ST-segment elevation myocardial infarction and thus may allow an earlier discharge of patients who are ruled out for non-ST-segment elevation myocardial infarction (ClinicalTrials.gov Identifier NCT01962506).
