{"title":"Left atrium: no longer neglected.","authors":"Andrea Rossi,&nbsp;Corrado Vassanelli","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Left atrial evaluation is strongly linked to the history of cardiac imaging. In the past, the importance of this chamber has been largely downplayed because cineangiography could not visualize it directly. Nowadays echocardiography can easily assess left and right atrial size and function. Left atrial enlargement is frequent in many cardiac diseases. A main determinant of left atrial volume is ventricular diastolic function. It has recently been suggested that left atrial volume might be the morphophysiologic expression of chronic diastolic function. In fact the left atrium is exposed directly to left ventricular diastolic pressure through the open mitral valve and because of its thin wall structure it tends to dilate with increasing pressure. Other important determinants of atrial volume are the degree of ventricular remodeling, mitral regurgitation and the presence of atrial fibrillation. The degree of left atrial enlargement is associated with adverse prognosis in different clinical settings. Patients with dilated cardiomyopathy and with a left atrial volume > 68 ml/m2 have a 3.8-fold risk compared with those with smaller left atrial volume. The predictive value of left atrial volume is independent of left ventricular systolic and diastolic function, mitral regurgitation and atrial fibrillation. This is noteworthy because these factors are both determinant of left atrial volume and have a strong impact on outcome. It might be concluded that left atrial volume represents a powerful predictive marker because it is a window allowing comprehensive evaluation of several factors associated with bad prognosis, which are often difficult to document separately.</p>","PeriodicalId":80289,"journal":{"name":"Italian heart journal : official journal of the Italian Federation of Cardiology","volume":"6 11","pages":"881-5"},"PeriodicalIF":0.0,"publicationDate":"2005-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25719196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 1999, a Working Group for Prehospital Emergency in Cardiology was established in Milan, and a network for 12-lead ECG transmission between advances life support (ALS) ambulances, the headquarter of 118 Rescue Service and the Coronary Care Units (CCU) or Divisions of Cardiology was developed: between February 1, 2001 and May 1, 2005, 6821 patients with suspected heart attack were rescued and their ECG recorded and transmitted (177 patients/month, 20% of them with an ST-segment shift, 11% ST-segment elevation, 9% non-ST-segment elevation, 24% with normal ECG). The rate of false positive automatic diagnosis of acute myocardial infarction was 0.3%, the rate of false negative was 0.8%. Forty-six patients with ventricular fibrillation underwent DC-shock. After May 1, 2004, clinical data of patients with STEMI transferred to the hospitals by ALS ambulances were reported in a database: 82% of the 89 patients were treated with primary angioplasty. The time (median, interquartile ranges) between ECG arrival to the CCU and the ECG report was 2 min (1-5), between ECG arrival to the CCU and patient arrival to the hospital was 34 min (24-42), between ECG arrival to the CCU and primary angioplasty was 69 min (50-93); the door-to-balloon time was 33 min (22-60). The telephone ECG transmission has been demonstrated to be a useful and rapid tool, easy to use; the automatic ECG diagnosis was accurate. In patients with STEMI the telephone ECG transmission shortened the time of delivery of therapy, helped to recover arrhythmic complications, allowed both the coordination between the 118 System and the Divisions of Cardiology and the implementation of the triage for primary angioplasty. Increasing the technological level of the service will be the next step of the program: the protocol will be upgraded in order to increase the number of patients rescued, to shorten the time of operation and to administer prehospital fibrinolytic therapy in selected patients.</p>","PeriodicalId":80289,"journal":{"name":"Italian heart journal : official journal of the Italian Federation of Cardiology","volume":"6 Suppl 6 ","pages":"49S-56S"},"PeriodicalIF":0.0,"publicationDate":"2005-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25866190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In other megatrials ACE-inhibitors were started in unselected patients 24 hours after AMI. Thus, the trend is to provide treatment as early as possible to less selected patients. Recently, ACE-inhibitors have been successfully tested not only to treat the consequences of an infarct, but also to prevent its occurrence. EUROPA is the trial that demonstrated that perindopril (8 mg/day) is indicated in all coronary artery disease patients to reduce cardiovascular mortality and occurrence of AMI.

Furthermore, these benefits seem to be reduced when applied to unselected patients with STEMI. Direct stenting represents an attractive strategy with potential benefits in terms of myocardial perfusion. Future randomized trials are needed to evaluate if this strategy is associated with a significant impact on outcome, and to provide cost-benefit analysis of an unrestricted use of drug-eluting stent in this high-risk subset of patients. Data from randomized trials have shown that the additional use of abciximab reduces mortality in primary angioplasty. Since the feasibility of long-distance transportation has been shown in several randomized trials, early pharmacological pretreatment may confer further advantages by early recanalization and shorter ischemic time, particularly in high-risk patients.
