A 64 years old man with multiple myeloma and low HDL.

In a 64 year old man with dyspnea and palpitation and fatigue and non angina chest pain, we found all the Para clinics prefect but only it showed low HDL and a normocytic, normochromic anemia. In searching about cause of anemia, in bone marrow biopsy showed Paraproteinemia. Therefore false low HDL because of paraproteinemia, leads to miss-diagnosis of cardiovascular disease.

Measurement of coronary sinus blood flow after first anterior myocardial infarction with transthoracic echocardiography and its correlation with wall motion scoring index.

OBJECTIVE: To measure the coronary sinus blood flow (CSBF) and coronary sinus velocity time integral (CSVTI) via transthoracic echocardiography (TTE) in patients with acute myocardial infarction (AMI) in association with the left ventricular ejection fraction (LVEF), and wall motion scoring index (WMSI). METHODS: In this case-control study, 20 patients with anterior AMI and 20 healthy individuals as the control group, were studied in 6 months period from March to September 2005 in Madani Heart Center, Tabriz, Iran. All patients received the same treatment for AMI (such as fibrinolytic). The CSBF, CSVTI, WMSI, and tissue Doppler imaging (TDI) data were obtained via TTE and compared between the 2 groups. RESULTS: Baseline variables were similar between the 2 groups (p>0.05). The CSBF in AMI group was 287.8 +/- 128 ml/min and in the control group was 415 +/- 127 ml/min (p=0.001). Also, CSVTI was significantly lower in AMI group than control group (11.16 +/- 2.85 and 17.56 +/- 2.72 mm, p=0.003). There was a significant correlation between CSBF and LVEF (r=0.52, p=0.01), WMSI (r=-0.77, p=0.0001) and CSBF and in-hospital mortality (r=0.58 p=0.03), also between CSVTI and LVEF (r=0.85, p=0.0001), WMSI (r=-0.57, p=0.0009) and in-hospital mortality rate (r=0.69, p=0.02). The CSBF and CSVTI had a good correlation with TDI findings: peak early diastolic velocity in the myocardium and peak systolic velocity in the myocardium). CONCLUSION: Our study demonstrated a good correlation between measured CSBF and CSVTI by 2D- Doppler TTE and LVEF, WMSI, in-hospital mortality and TDI findings.
