[Management strategies and choice of antithrombotic treatment in patients admitted with acute coronary syndrome--executive summary for clinical practice. Consensus Document of the Regional Chapters of the Italian National Association of Hospital Cardiologists (ANMCO) and of the Italian Society of Emergency Medicine (SIMEU)]

This document has been developed by the Lazio regional chapters of two scientific associations, the Italian National Association of Hospital Cardiologists (ANMCO) and the Italian Society of Emergency Medicine (SIMEU), whose members are actively involved in the everyday management of Acute Coronary Syndromes (ACS). The document is aimed at providing a specific, practical, evidence-based guideline for the effective management of antithrombotic treatment (antiplatelet and anticoagulant) in the complex and ever changing scenario of ACS. The document employs a synthetic approach which considers two main issues: the actual operative context of treatment delivery and the general management strategy.

Comparison of immediate vs early invasive strategy in patients with first acute non-ST-elevation myocardial infarction

BACKGROUND

The best timing for coronary angiography (immediate vs early) in patients with acute non-ST-elevation myocardial infarction (NSTEMI) is controversial.

HYPOTHESIS

Evaluate in NSTEMI patients the effects of an immediate compared to an early invasive strategy on microvascular damage, myocardial perfusion, and infarct size.

METHODS

We randomized 54 consecutive patients with first episode of NSTEMI: 27 patients (22 males, age 58.8 ± 9.4 years, group A) underwent immediate (≤6 hours) percutaneous coronary intervention (PCI) with a double bolus of eptifibatide, and 27 patients (24 males, age 59.7 ± 9.8 years, P = 0.72, group B) underwent early (7-72 hours) PCI with upstream eptifibatide. Microvascular damage was evaluated at predischarge by myocardial contrast echocardiography, and the contrast defect length was calculated.

RESULTS

There were no significant differences in pre-PCI myocardial blush grade (MBG) (41% MBG 0 or 1 in group A vs 37% MBG 0 or 1 in group B, P = 0.78), in post-PCI MBG (7.4% MBG 0 or 1 in both groups, P = 1.00), and in contrast defect length (4.5% in group A vs 2.8% in group B, P = 0.56). However, group A showed a significant reduction in creatine kinase myocardial band isoenzyme peak (26 ± 26 ng/mL in group A vs 69 ± 79 ng/mL in group B, P = 0.01) and in troponin T peak (0.84 ± 1.2 ng/mL in group A vs 1.8 ± 2.1 ng/mL in group B, P = 0.048).

CONCLUSIONS

In patients with NSTEMI treated with eptifibatide, immediate PCI is associated with less increase in myonecrosis markers compared with PCI within 72 hours. There were no significant differences in myocardial perfusion between the 2 strategies.

Tachycardia-induced cardiomyopathy: mechanisms of heart failure and clinical implications

The prognosis of dilated cardiomyopathy is generally poor. The cause of ventricular dysfunction often cannot be identified. In most cases, the clinical history of cardiomyopathy is irreversible but, in some cases, potentially curable causes may be identified. The development of cardiomyopathy may be correlated to atrial or to ventricular arrhythmias. In this scenario, atrial fibrillation is the most frequent cause of ventricular dysfunction, even if it may also be secondary to heart failure. The diagnosis of tachycardia-induced cardiomyopathy can be made only after the improvement of the left ventricular function once the cardiac frequency has slowed down.

Recovery of cardiac function after ablation of atrial tachycardia arising from the tricuspid annulus

Tachycardia-induced cardiomyopathy is a reversible form of heart failure. An early diagnosis and an effective cure of the underlying tachycardia are crucial for a favorable outcome. Different kinds of atrial and ventricular arrhythmias may induce tachycardiomyopathy. Focal atrial tachycardia may be easily suppressed by means of transcatheter ablation. Relationships between focal atrial tachycardia and tachycardiomyopathy have not been deeply analyzed. In the present paper we report a case of a 76-year-old man with tachycardia-induced cardiomyopathy caused by recurrences of focal atrial tachycardia arising from the tricuspid annulus. The arrhythmia was successfully treated with transcatheter ablation. In the follow-up no recurrences of the arrhythmia occurred and a significant improvement in myocardial function was observed.

[Possible relationship between childhood malaise and psychiatric disorders in adulthood. Preliminary study on an in-patient sample from the psychiatric unit of the general hospital in Pavia]

The authors report the preliminary data of a study which aims to identify the variables (socio-demographic, clinical and nosographic) which may be used to predict the evolution of psychiatric disorders. A retrospective follow-back study was carried out using the medical records and any other documentation available from medical and psychological centers in order to identify the evolutionary stages of disease and possible pre-disease antecedents. The sample group examined was selected from users attending the Diagnosis and Treatment Psychiatric Unit at Pavia Hospital who were found to have undergone infantile neuropsychiatric outpatient or hospital treatment during childhood. The preliminary phase of the study reports the results of the first 42 cases. The predictive value of the diagnosis made during childhood emerges from an analysis of the results and consequently emphasises the need to orient Infantile Neuropsychiatric structure not only towards diagnosis and care but also, towards a more strictly therapeutic action.
