Abstract

A 95-year old woman was admitted to our emergency unit because of acute abdominal pain. After urgent surgery according to the acute abdomen, she was referred to intensive care unit (ICU) of the emergency unit as she was intubated. It was developed a run of new arrhythmia which was diagnosed by cardiology resident as bidirectional ventricular tachycardia due to beat to beat changing the axis of the QRS. However, a second and more precise evaluation of the abnormal ECG suggested a narrow supraventricular tachycardia, most probably AV nodal reentrant tachycardia with a 2:1 right bundle branch block.

Abstract

The femoral artery pseudoaneurysm is a disturbing groin complication associated with the femoral arterial access site used for invasive cardiovascular interventions. We present a 39 year old man who developed a huge right common femoral artery pseudoaneurysm, following diagnostic coronary artery catheterization, which was successfully managed with stent-assisted coiling, an emerging and narrative option in invasive percutaneous approaches to femoral artery pseudoaneurysm.

Abstract

Background. Coronary artery disease (CAD) is uncommon among young adults and may have certain characteristics that are different from those in older patients. The aim of the current study was to determine the risk factors of CAD, important laboratory data and angiographic findings in young patients with CAD and to compare them with the old patients.

Methods. Patients with typical chest pain whose CAD was confirmed by coronary angiography were included in the study. These patients were divided into 2 groups: ≥ 45 and < 45 years old; the risk factors of CAD and angiographic findings were determined in each group and further compared.

Results. Finally, 231 patients with CAD were included in the study. Thirty-five (30.4%) of patients younger than 45 years and 58 (50.0%) aged ≥ 45 had diabetes mellitus (P = 0.002). Statistically remarkable differences were observed between the two groups regarding hypertension (P < 0.001), myocardial infarction (P < 0.001), Gensini score Median (P < 0.001), ejection fraction in echocardiography (P < 0.001) and fasting blood sugar in laboratory data (P = 0.006). The older group, compared with the younger one, had higher left anterior descending (LAD) artery (P < 0.001), right coronary artery (RCA) (P < 0.001), 3 vessel disease (P < 0.001) and 2-vessel disease (P = 0.044); on the other hand, 1-vessel disease was higher in patients aged < 45(P < 0.001).

Conclusion. The risk profile and angiographic findings are different in young patients with CAD compared to older patients. Young patients with CAD tend to be male with a positive familial history, but with less diabetes or hypertension. The older patients had higher 3 vessel disease, 2-vessel disease and left anterior descending (LAD) artery and right coronary artery (RCA) involvements. In contrast, 1-vessel disease was higher in young patients aged <45.

Abstract

Background. Recent studies have confirmed the essential and paramount role of the L-Citrulline on the nitric oxide regulation and the endothelial function improvement.

Materials and Methods. In this cross-over clinical trial, thirty patients, diagnosed with coronary artery disease (CAD) and flow mediated dilation to nitroglycerin dependent vasodilation (FMD/NMD) ratio less than 1, were included. The patients were randomly divided into two groups of 15 patients and underwent treatment by L-Citrulline or placebo for 15 days, in 2 step protocol. The indicators of assessment in the current study were the ratio of the FMD/NMD and FMD value.

Results. In the current cross-over clinical trial, the mean of FMD to NMD ratio and mean FMD value of all patients before starting the protocol were 0.91 ± 0.08 and 4.04 ± 0.51 mm, respectively. The final results of study showed that following L-Citrulline administration, mean FMD to NMD ratio and mean FMD value were enhanced to: 1.03 ± 0.09 and 4.96 ± 0.72 mm, respectively, which were statistically significant (P<0.001 and P<0.001, respectively). However, following placebo administration, mean FMD to NMD ratio and mean FMD value were receded to: 0.92 ± 0.09 and 4.06 ± 0.22 mm, respectively, which were not statistically significant (P = 0.75 and P = 0.89, respectively). Moreover, the improvement of mean FMD to NMD ratio (0.12 ± 0.02) and mean FMD value (0.92 ± 0.16 mm), following L-Citrulline administration, were statistically significant in comparison with the change of mean FMD to NMD ratio (0.01 ± 0.002) and mean FMD value (0.02 ± 0.003), following placebo administration (P<0.001 and P<0.001, respectively).

Conclusion. L-Citrulline treatment can lead to improvement of the endothelial function in patients diagnosed with CAD which are assessed via FMD to NMD ratio FMD value enhancements.
