ConclusionPatients with a delayed presentation after CS-STEMI were younger and more likely to have single-vessel disease. We found a high in-hospital mortality of 42.9%. Appropriate randomized studies are required to evaluate the optimal treatment strategies in these patients.

ConclusionsThe NETest exhibits clinically competent metrics as an effective biomarker for neuroendocrine tumors. Measurement of NET transcripts in blood is a significant advance in neuroendocrine tumor management and demonstrates that blood provides a viable source to identify and monitor tumor status.

Conclusion: The data from the current study indicated that the preoperative management of pheochromocytoma with single α-receptor blocker PXB for more than 2 weeks, after the final dose adjustment, could not further reduce the risk of intraoperative hemodynamic instability or postoperative complications. Thus, our study supports that 14 days would be enough for the duration of preoperative management of pheochromocytoma with single α-receptor blocker PXB in final dose.

A middle aged woman with few serious medical issues presented with altered mental status, had a generalized tonic clonic seizure, and was found to be hypertensive and tachycardic. An ECG was recorded:What is it?The computer measures QRS duration as 126 ms.This is a regular, wide complex tachycardia, but not very wide. There are no P-waves. The QRS has 2 alternating morphologies, both of which are right bundle branch block (RBBB) in configuration, but which have different axes. Both complexes have an rSR'in lead V1 and a wide S-wave in V6.One might suspect that the higher voltage beats are premature beat...

Giant wide T inversion may be seen in all except: a) After a cardiac arrest b) Subarachnoid hemorrhage c) Hyperkalemia d) Takotsubo cardiomyopathy Correct answer: c) Hyperkalemia Giant T wave inversion can be broad and deep or just deep T inversions. A depth of T wave of 10 mm or above is generally considered as deep T inversion [1]. Giant T wave inversions with depth of 35 mm have also been described in literature [2]. Deep T inversions without gross increase in width can occur in ischemia and hypertrophic cardiomyopathy. In a study involving 864 patients with hypertrophic cardiomyopathy, 15% had giant T wave in...

We report three cases of pheochromocytoma in females presenting with ventricular arrhythmia; two had torsades de pointes and a third patient had frequent VPCs and nonsustained ventricular tachycardia. All the patients were treated with surgical removal of the tumor with complete relief of symptoms and normalization of QT interval. PMID: 27316501 [PubMed - in process]

Abstract: Pheochromocytomas are neuroendocrine tumors, and its cardiac involvement may include transient myocardial dysfunction, acute coronary syndrome (ACS), and even ventricular arrhythmias. A patient was referred for evaluation of stuttering chest pain, and his electrocardiogram showed T-wave inversion over leads V1 to V4. Coronary angiography showed 90% stenosis in the mid-left anterior descending coronary artery (LAD), which was stented. Five days later, the patient had ventricular tachycardia, and severe hypertension, remarkable blood pressure fluctuation between 224/76 and 70/50 mm Hg. The patient felt abdominal p...
