Prognosis and first diagnostic ECG in STEMI patients referred to the emergency medical system for primary PCI.

BACKGROUND: Pathological Q waves (QWs) in the first ECG recorded at hospital admission has been found to correlate with myocardial damage and mortality in STEMI patients. We investigated the association between new QWs recorded in the pre-hospital setting and adverse outcome during the hospital stay. METHODS: A pre-hospital ECG was recorded in 248 patients with STEMI who underwent primary PCI. Patients were divided into two groups based on the presence (n = 44, QWs) or absence (n = 204, non-QWs) of new QWs. RESULTS: Patients with new QWs had a higher prevalence of anterior infarct, cardiogenic shock and a lower LV ejection fraction. In-hospital mortality was higher in patients with new QWs. The percentage of patients with new QWs increased progressively with increasing pain to ECG time. CONCLUSIONS: New QWs provide rapid prognostic information in the pre-hospital phase of STEMI by identifying patients at risk of adverse outcome during the hospital stay.

Feasibility, symptoms, adverse effects, and complications associated with noninvasive assessment of coronary flow velocity reserve in women with suspected or known coronary artery disease.

BACKGROUND: Microvascular coronary impairment, defined as reduced coronary flow reserve, represents the predominant etiologic mechanism of ischemia in women with chest pain and no obstructive coronary artery disease. Transthoracic echocardiography (TTE) is a noninvasive method for assessing coronary flow velocity reserve (CFVR) in the left anterior descending coronary artery (LAD). The purpose of this investigation was to define the safety profile, feasibility, adverse events, and rate of complications of the test in women with suspected CAD. METHODS: We evaluated CFVR in LAD with TTE during adenosine infusion in 1455 women aged 66.4±11.9 years. RESULTS: A complete CFVR study was achieved in 1429 pts (feasibility 98.2%), the test being performed also in the early phase of acute coronary syndrome and on obese patients. Minor symptoms or adverse effects occurred in 43.7% of patients not requiring test termination: hyperpnea (16.7%), flushing (9.4%), atypical chest pain (9.9%), headache (6.6%), minor arrhythmias (2.9%), chest pain with EKG changes (1.5%) were the symptoms reported. No major complications were observed. CONCLUSIONS: Noninvasive assessment of CFVR in LAD by TTE is a very feasible method with very low incidence of adverse events and complications in women with suspected or known CAD. It is safe and can be used when evaluating female patients with atherosclerotic LAD disease or with coronary microvascular impairment.

[Hypnosis in transesophageal echocardiography. The experience in a Pediatric Cardiology and Congenital Heart Disease Unit]. / L'ipnosi nell'ecocardiografia transesofagea. L'esperienza di un Centro di Cardiologia Pediatrica e delle Cardiopatie Congenite.

BACKGROUND: The purpose of this study was to use hypnosis in patients with congenital heart disease undergoing transesophageal echocardiography (TEE). METHODS: From January 2016 to July 2017, 50 adult patients undergoing TEE were randomly assigned to two groups: TEE in hypnosis (n = 23), TEE in sedation (n = 27). Vital parameters (heart rate [HR], blood pressure [BP], oxygen saturation [SO2] before, during and after the procedure) and drug administration were recorded. The State-Trait Anxiety Inventory was performed before and after TEE, the memory and experience of TEE through a structured interview were assessed. RESULTS: All patients in the hypnosis group performed TEE without any sedation. As for anxiety before TEE, no significant differences were observed between groups; after TEE all patients were less anxious than at the beginning (p<0.001) with a greater decrease in patients of the hypnosis group (p<0.001). Before TEE, there were no significant differences also in HR, BP and SO2. During TEE in both groups a similar increase in HR and BP was found (p<0.001), whereas SO2 values remained stable. In the responses to the structured interview, 94% of patients in the sedation group remembered everything vs 36% of the hypnosis group (p<0.05). No differences were found in the other answers between the two groups. CONCLUSIONS: Hypnosis in TEE is useful to improve the emotional experience of patients with congenital heart disease.
