Abstract:

Seventy four years old, caucassian female patient brought in to emergency department for an acute onset and deteriorating dyspnea. A DDD-R pacemaker was implanted seven years ago because of complete AV block. Previous routine follow-up exams and pacemaker technical values were within normal limits in all 7 years. But she was in atrial fibrillation in last follow up which was one month ago before detecting thrombus in pacemaker lead. Transtorasic echocardiography revealed a 1.5 x3.0 cm trombus in the right atrium attached to the lead (Figure 1). Patient was admitted to cardiovasular surgery intensive care unit with a plan for surgery because of large thrombus. Electrode-associated right atrial (RA) thrombus appears to be relatively common in acute period after pacemaker implantation and It’s usually asymptomatic. Patient’s previous follow-ups were within normal limits in 7 years. Probably an electrode-associated RA thrombi in this case has been happened after atrial fibrillation started and she has been taking no anticoagulan medicine. The important point which makes this case novel is there wasn’t thrombus formation before the patient was in AF in 7 years . According to best of our knowledge, there is no preivous case presented as atrial fibrillation associated pace maker lead thrombus in late period after lead implantation. It’s important to initiate anticoagulation as soon as the AF is detected, in patients with pacemakers. It is important that thrombus can occur in right chambers of heart beacuse of pacemaker electrodes.

Abstract:

Electric shock induced myocardial infarction is a rare condition. Electric shocks can lead to a wide vairety of clinical conditions from skin burns to fatal arrhythmic complications. Coronary angiogram of those patients are usually normal. Coronary thrombosis after electric shock has been accused of this consequence. The right coronary artery is the most affected artery. It’s believed to be due to the location of the right coronary artery, which is in close proximity to the chest wall. This case is about a 49 years old female patient presented with myocardial infaction right after an electric shock. The coronary angiogram revealed right coronary artery dissection. According to best of our knowledge, this is first case in the literature. The complete revascularization was achieved by implantation of a bare metal stent in the dissection site.

Abstract:

Introduction: Rheumatoid arthritis is a systemic inflammatory disease that has pulmonary system involvement. Fibrosis of the lungs and interstitial lung disease are associated with RA in some patients, and early diagnosis is a cornerstone in treatment. Pulmonary artery distensibility has been investigated using MRI and echocardiography. It has been found well correlated with the severity of pulmonary hypertension.The aim of this study was to investigate whether echocardiographic measurement of the right pulmonary artery distensibility (percentage change in diameter of the right pulmonary artery in systole and diastole) may be of value in assessing the presence of pulmonary disease before it is symptomatic or it can be diagnosed by conventional methods. Materials and Methods: Forty-three patients (6 male, mean age: 55.3±12.3, mean disease duration:12.9±9.7 years) with RA and age and sex matched 18 healthy subjects ( 4 male, mean age: 42.6±15.7 ) recruited for the study. The body mass index values were similar in both groups. The RA group was clear of lung involvement proved with symptoms and chest x-rays. Mean pulmonary arterial blood pressure is normal in both groups (patient and control). In addition to conventional echocardiographic evaluation all subjects are evaluated for right pulmonary artery distensibility index (RPAD Index), which is calculated as the difference in diameter of the right pulmonary artery in systole and diastole. All echocardiographic measurements were done by two cardiologists and Both inter- and intraobserver variabilities were < 5% for all echocardiographic variables. Findings: Mean RPAD was 0.17 ±0.05 mm in patient group and 0.21±0.06 mm in control group. RPAD was higher in patient group but there wasn’t a statictically significant difference for RPAD between patient and control group Results: According to our results, RPAD is worsened in patients with RA, but it’s not significant. Low RPAD may be an early sign of lung involvement in RA and it should be verified with follow-ups for longer duration closely.

Abstract:

Introduction: Atherosclerosis is a chronic, inflammatory and focal disease of the middle and large arteries. Coronary arteries, popliteal arteries and internal mammarian arteries (IMA) are middle sized arteries and they are prone to early atherosclerosis. Conventional risk factors of atherosclerosis (hypertension, diabetes mellitus, hyperlipidemia, advanced age, smoking, male sex) are a sign of extension of atherosclerosis and their existence correlated well with pulse wave velocity (PWV). Increased PWV is also an independent risk factor for cardiovascular mortality and morbidity. IMA is the most widely preffered artery for anastomosis in coronary artery bypass grafting (CABG). Because IMA is also an artery that is prone to atherosclerosis, the size and the blood flow through IMA has always been an interest for surgeants preoperatively. We investigated the relationship between PWV and IMA size ve blood flow in patients who are candidates for CABG. Material and Method: We recruited 21 patients (16 male, mean age 64,3) planned for CABG operation. Aortic PWV values are evaluated by echocardiography (GE, vivid E9, Solingen, Germany). IMA size and flow parameters are evaluated intraoperatively by cardiovasular surgeants. Findings: According to the early resuts of this prospective study, mean aortic PWV value was 9,32±1,69 m/sec, mean IMA diameter was 1,53±0,05 cm and mean IMA flow was 29,2±1,2 cc/min. Results:We found a statistically significant correlation between the IMA flow and IMA diameter (p < 0,05). But there wasn’t a significant correlation between the IMA flow or diameter and PWV (p > 0.05). According to our study, aortic pulse wave velocity can not predict IMA flow or IMA diameter.

Abstract:

Objectives: The main objectives of this clinical case presentation is to attract attention about the situation from our medical practice when we can have a patient with typical constrictive chest pain like in ischemic heart disease but with normal EKG in crisis. Confers this normal EKG us safe that the patient is not in dangerous situation?
Material And Methods: I present the clinical case of a women patient 46 years old, in early menopause because of stressful situation in she’s family, who came at consultation with sudden constrictive chest pain, high intensity, irradiation in to the left shoulder, anxiety and sweating. Mention, very important, that the EKG was normal without ischemic – lesions changes in crisis of chest pain, but the pain disappeared immediately in 2 min after one drug 0,5mg of Nitroglycerine under the tongue. Because the patient was in menopause (so lost the estrogen protection for atherosclerosis and heart attack) in this stressing condition at home I have decided to be hospitalized for more safe indifferent that the pain stopped at the moment and the EKG was normal without any changes. After hospitalization however the EKG was normal the patient start the correct protocol for ischemic heart disease: beta-blocker, nitrate, aspirin, statine drugs and NTG under the tongue if she need. The blood tests were in normal range and cardiac enzymes as well. Only the level of cholesterol=250mg/dl was increase.
In the second day, in the morning, the patient present severe chest pain, constrictive, sweating, anxiety and was necessary perfusion with nitroglycerin to stopped the pain in 10min, but unusual the EKG in crisis was again normal and the level of cardiac enzymes were the same in normal range. In the third day in the morning the patient presented again constrictive chest pain, anxiety, sweating and was necessary again administration the perfusion of nitroglycerin to stopped the pain in approximate 15 minutes, because wasn’t stopped after NTG drug 0,5 mg under the tongue, but the EKG repeated in crisis was again normal and the level of cardiac enzymes remained normal as well. An echocardiography of the heart was performed to exclude the dissection of the aorta but was normal and the therapy was completed with Fraxiparine 0,4UI sc twice per day at 12 hours. In the third day because of repeated crisis of chest pain the patient was referred to the Surgery Cardiovascular Department and a heart coronarography was performed and surprising three coronary arteries were narrowing with 75%. So a severe left main or three-vessel disease stenosis of coronaries arteries was discover and the patient performed three stents implantation with good evolution.
Results and Discussions: How was possible that the EKG to be normal three days consecutively in context of these severe repetitive constrictive chest pain? when perfusion with nitroglycerin was necessary to be administrated repeated to stoped the pain and the level of specific cardiac enzymes were normal as well and excluded a heart attack.
Conclusion: The most important conclusion of this clinical case presentation is that a normal EKG (without ischemic - lesions changes) in a typical crisis of constrictive chest pain, don’t give us safe that the patient don’t have nothing and is better to start the standard protocol of therapy for ischemic heart disease, if the characteristics of chest pain are so typical clinic for angina pectoris, to protect our patient and to be in safe. A normal EKG in typical crisis of chest pain doesn’t exclude the diagnosis of ischemic heart disease. In our actual standard protocol in these situations the effort test should be perform but could be iatrogenic and dangerous. Except this clinical case report, in my medical practice, I have saw many clinical cases in the similar situations, for this reason I start the standard protocol of therapy for ischemic heart disease at these categories of patients with normal EKG to prevent sudden death. The typical chest pain with normal EKG in crisis could hide a very severe and risky ischemic heart disease with many severe stenosis of the coronaries arteries and don’t give us safe that the patient is not in danger.

Abstract:

Background: Pulmonary arterial hypertension (PAH) is a progressive and life-threatening disease associated with high morbidity and mortality rates. However, the exact regulatory mechanism of PAH is unknown. Although mitochondrial coupling factor 6 (CF6) is known to function as a repressor, its role in PAH has not been explored. Objective: We investigated the involvement of endogenous CF6 in the development of PAH. Methods and Results: PAH was induced with monocrotaline (MCT), as demonstrated by significant increases in pulmonary artery pressure and vessel wall thickness (p<0.01). CF6 upregulation was confirmed by quantitative RT-PCR and ELISA. Immunohistochemistry analysis revealed a large amount of CF6 localized to all three layers of the vascular wall and the surrounding tissues in the PAH rats; however, it was barely detectable in endothelial cells (ECs). A total of 2×1010 gp of adeno-associated virus (AAV) was used for transduction of CF6 short hairpin RNA (shRNA) or a control vector, which was intratracheally transfected into the rats before or after MCT injection. The CF6 shRNA effectively reduced the CF6 mRNA and protein levels in the PAH rats and also reversing the 6-keto-PGF1a levels in circulation and in lung tissue (p<0.05). Finally, we found that CF6 shRNA reduced inflammatory infiltration, reversed endothelial dysfunction and vascular remodeling and ameliorated the severity of pulmonary hypertension and right ventricular dysfunction (p<0.05) at 4 weeks when it was used as both a pretreatment and rescue intervention. Conclusions: CF6 contributes to the pathogenesis of PAH, and it may function in association with prostacyclin. The blockage of CF6 could reverse the progression of PAH; thus, it might be applied as a novel therapeutic approach.

Abstract:

Background- CRT (Cardiac Resynchronization Therapy) has been approved beneficially in heart failure patients with refractory optimized medical therapy on based of many studies. The guidelines have shown CRT is indicated in NYHA class III-IV, QRS >150 ms, LBBB (Left bundle branch block) to improve heart functions, ventricular remodeling and clinical symptoms. Purpose-comparison of stress induced mechanical dyssynchrony between rate dependent LBBB and RBBB (Right bundle branch block) and beneficial role of CRT to improve LV function and reduce mortality. Method-Patients presenting dyspnea on exertion NYHA class I-II to III-IV by stress test , normal QRS to rate dependent LBBB or RBBB by Stress test or Dubutamine Stress Echo were studied. CRT on cardiac function was assessed by Cath study, Echo and MRI (Magnetic Resonance Imaging). Result- 46 Patients, male/female ratio (1.87), 12 months observational study done on stress induced rate dependent LBBB and RBBB with worsening dyssynchrony and poor LV function were treated with CRT. Results have shown improved LV function in rate dependent LBBB patients (31+/-6 %) v/s RBBB patients (4.5+/-4%) with P value <0.04. and reduce mortality among rate dependent LBBB with CRT v/s without CRT ( 5% v/s 20 %) and another side mortality difference between rate dependent RBBB with CRT and without CRT were not found significantly. Conclusion- Stress induced rate dependent LBBB with mechanical dyssynchrony leads to heart failure is benefited by CRT than Rate dependent RBBB.
