[Myocardial infarction in the 34th week of gestation: case report]

Acute myocardial infarction during pregnancy is a rare event that is often associated with a very high maternal mortality, estimated to be from 19 to 37%. During the last decades the incidence of myocardial infarction during pregnancy has increased . The main contributing factor could be a higher prevalence of the metabolic syndrome. The strongest predictors correlated with a myocardial infarction are hypertension, diabetes mellitus and advanced maternal age. In addition, improved diagnostic tools could explain the elevated incidence of myocardial infarction during pregnancy. In general gestation is not considered a risk factor for myocardial infarction but gravidity is accompanied by an increase in oestrogen and progesterone levels. It is generally accepted that oral contraceptives increase the risk of coronary heart disease. We present a case where a 37-year-old gravida was admitted to hospital with diffuse thoracic pain. In the patient's history, we found several putative reasons for the thoracic pain that pointed to a musculoskeletal cause. Based on an elevation of ischaemic heart markers and continuous non-specific thoracic pain we performed a primary Cesarean section. In the coronary angiography procedure that followed, a thrombotic occlusion of the ramus diagonalis was diagnosed. We here describe the differential diagnosis as well as the problems associated with diagnosing myocardial infarction in the third trimester of pregnancy.

Whole-body multislice computed tomography (MSCT) improves trauma care in patients requiring surgery after multiple trauma

OBJECTIVES

Whole-body multislice helical CT becomes increasingly important as a diagnostic tool in patients with multiple injuries. Time gain in multiple-trauma patients who require emergency surgery might improve outcome. The authors hypothesised that whole-body multislice computed tomography (MSCT) (MSCT trauma protocol) as the initial diagnostic tool reduces the interval to start emergency surgery (tOR) if compared to conventional radiography, combined with abdominal ultrasound and organ-focused CT (conventional trauma protocol). The second goal of the study was to investigate whether the diagnostic approach chosen has an impact on outcome.

METHODS

The authors' level 1 trauma centre uses whole-body MSCT for initial radiological diagnostic work-up for patients with suspected multiple trauma. Before the introduction of MSCT in 2004, a conventional approach was used. Group I: data of trauma patients treated with conventional trauma protocol from 2001 to 2003. Group II: data from trauma patients treated with whole-body MSCT trauma protocol from 2004 to 2006.

RESULTS

tOR in group I (n=155) was 120 (90-150) min (median and IQR) and 105 (85-133) min (median and IQR) in group II (n=163), respectively (p<0.05). Patients of group II had significantly more serious injuries. No difference in outcome data was found. 14 patients died in both groups within the first 30 days; five of these died within the first 24 h.

CONCLUSION

A whole-body MSCT-based diagnostic approach to multiple trauma shortens the time interval to start emergency surgery in patients with multiple injuries. Mortality remained unchanged in both groups. Patients of group II were more seriously injured; an improvement of outcome might be assumed.
