[Coronary disease: early intervention saves lives. Treatment of acute myocardial infarction in Mantova: results of thirty months of work after the implementation of a province network]. / Malattia coronarica: l'intervento precoce salva la vita. Terapia dell'infarto miocardico acuto a Mantova, risultati di trenta mesi di attivita' dopo l'attivazione di una rete provinciale.

BACKGROUND: Since June 2001, in the province of Mantova, we have undertaken a program for the management of acute myocardial infarction based on the early assessment of patient risk profiles, concerning telematic connections among care centers and on the optimization of in-hospital and out of hospital critical pathways for access to care. MATERIALS AND METHODS: Our network provides connections among the following centers: advanced life support ambulances, seven hospitals, three coronary care units, one cath lab on call 24 h a day for primary angioplasty, and one thoracic surgery division. This program, through its strong telematic platform, allows the early assessment of myocardial infarction and provides primary angioplasty to all high-risk patients, as fibrinolytic treatment is reserved only for low-risk patients admitted in peripheral hospitals. RESULTS: Two hundred and eighty patients with acute myocardial infarction were treated with angioplasty; 224 patients (80%) underwent primary angioplasty, 36 patients (13%) facilitated angioplasty and 20 patients (7%) rescue angioplasty. One hundred and thirty-two patients (47%) were first admitted to Mantova Hospital; 78 patients (28%) were referred to Mantova from peripheral hospitals and 70 patients (25%) were directly transported to the cath lab by advanced life support ambulances. Procedural success was obtained in 98% of patients, with 0.4% intraprocedural mortality. In-hospital mortality was 5.7%, while mortality in cardiogenic shock patients was 36%. The recurrence of acute myocardial infarction occurred in 1% of patients and major bleeding occurred in 2.2% of patients. One patient with cardiogenic shock died during transport. Mean door to balloon time was 67 min with a 42% reduction in the 3rd recruitment period. CONCLUSIONS: This program, developed in the setting of a provincial network for the management of acute myocardial infarction, provided primary angioplasty to all high-risk patients, with a high procedural success rate. Within a few months, time to treatment was minimized by the use of telematic facilities.

Renal infarction: an uncommon mimic presenting with flank pain.

A 39-year-old woman arrived to the emergency department complaining of a constant, progressive, left flank pain, with no beneficial effect from spasmolytic and nonsteroidal antiinflammatory drugs. Two years before, she suffered another episode of right flank pain and stranguria, but instrumental examinations (ultrasonography, urography) remained negative. Besides a mild tenderness in the left flank, physical examination was normal. Blood chemistry panel showed leukocytosis (17.2 x 10(3) mL, neutrophils 82.8%) and a slight increase of serum lactate dehydrogenase (LDH) (543 U/L versus 230 to 460 U/L). Urinanalysis showed a slight hemoglobinuria (0.5 mg/dL), and sediment contained some red cells and leukocytes. Diagnostic examinations (ultrasonography, computed tomography) showed a left renal nonhomogeneous space-occupying lesion, orientative for renal malignancy. She was transferred to the urology department and operated. Both intraoperatory and histological diagnosis was ischemic infarction and, after exclusion of all possible underlying causes, final diagnosis was idiopathic renal infarction. Diagnostic procedures and literature reports are discussed.
