ABSTRACT
Acute myocardial infarction (AMI) has a high mortality rate and poor prognosis for patients. The primary causes of death are arrhythmia and heart failure. For patients admitted because of myocardial infarction, various risk evaluations are initiated to foresee possible complications. The thrombolysis in myocardial infarction (TIMI) risk score, which can be used to predict the prognosis and the need for revascularisation, is the most convenient and commonly used system, but is inadequate for AMI patients on admittance. Fragmented QRS (fQRS) has been shown to be a valuable electrocardiographic (ECG) index for predicting the prognosis of patients with coronary heart disease. Also, fQRS is considered to predict an increased likelihood of a poor outcome and mortality in patients with coronary artery disease (CAD), even for some successfully revascularized AMI patients. So what would happen if fQRS and the TIMI risk score were combined? This study focused on the investigation of the short-term prognostic value of fQRS combined with the TIMI risk score for patients with AMI.

Objective To analyze the etiological or associated factors and the treatment of patients with atrial fi brillation in high altitude areas in Tibet. Methods The clinical data of atrial fi brillation patients hospitalized in our hospital during January 2012 to Jane 2016 were analyzed retrospectively. Results (1) A total of 442 patients (male:female,1.2:1) were included in the study with ages of 30-96(65.9±12.3) years. The percentages of paroxysmal, persistent and permanent atrial fi brillation were 14.9%, 69.2%, and 15.8% respectively. The associated factors of atrial fi brillation included hypertension (53.4%), rheumatic heart disease (7.5%),chronic mountain sickness (10.6%), coronary heart disease(5.7%), hyperthyroidism (6.1%) and diabetes (9.0%).(2)Only 42 patients (9.5%) had evaluation with CHADS2score during hospitalization and actually 74.6% patients scored≥2. Twenty-one patients were restored to sinus rhythm during hospitalization and no patients had radiofrequency ablation.Conclusions The associated factors of atrial fi brillation in high altitude areas are similar to other areas. Thrombosis risk evaluation and anticoagulation therapy was not sufficient. Rhythm control rate was low and development of radio frequency ablation therapy should be considered.
