Potential link between Helicobacter pylori and ischemic heart disease: does the bacterium elicit thrombosis?

Over the past fifteen years, numerous observations have linked Helicobacter pylori (H. pylori) infection to ischemic heart disease (IHD). Despite the controversial literature data, it has been postulated that if a role is plausible, it will be in the early events of the acute coronary syndrome.

Clinical and biochemical parameters related to cardiovascular disease after Helicobacter pylori eradication.

Aim: Since the major established risk factors explain the pathogenesis of ischemic heart disease (IHD) in a proportion of cases, it is crucial to search for other causal mechanisms. The possible link between IHD and Helicobacter pylori (H.pylori) infection has been reported.

Chest wall and hemidiaphragm reconstruction with Gore-Tex mesh and omolateral latissimus dorsi flap. A case report.

There are various method of reconstruction when chest wall resection is performed for the treatment of tumors of the chest wall. In this case a chest wall resection and reconstruction was performed using an omolateral latissimus dorsi flap, together with Gore-Tex mesh. A 42-year-old woman was diagnosed as having a huge low grade chondrosarcoma and underwent surgical resection which interested the anterior chest wall from the level of the IV to X rib and the right hemidiaphragm.

Is dobutamine stress echocardiography predictive of middle and late term outcomes in mitral stenosis patients?

Aim: In mitral stenosis (MS) patients with a poor symptom-echocardiography correlation, dobutamine stress echocardiography (DSE) still does not have a confirmed utility and predictive value. Our aim is to evaluate usefulness of DSE in assessing 2 and 5 years clinical outcomes.

Methods: Forty-four consecutive patients with known MS were submitted, between April 1998 and July 1999, to basal and DSE.

Updated review (2006) on Helicobacter pylori as a potential target for the therapy of ischemic heart disease.

Unlabelled: Despite knowledge about the classical risk factors for ischemic heart disease (IHD) has increased, all the differences in morbidity as well as mortality from this disease cannot be fully explained. Hence the importance of looking for other causal mechanisms. Numerous infectious agents have been linked to IHD and among these also Helicobacter pylori (H.

Thrombopoietin contributes to enhanced platelet activation in patients with unstable angina.

Objectives: We sought to investigate the potential role of elevated levels of thrombopoietin (TPO) in platelet activation during unstable angina (UA).

Background: Thrombopoietin is a humoral growth factor that does not induce platelet aggregation per se, but primes platelet activation in response to several agonists. No data concerning its contribution to platelet function abnormalities described in patients with UA are available.

Surgical revascularization in the ischemic heart disease. Long-term results in a series of consecutive patients selected according to the principles.

Aim: Ischemic heart disease can be treated with drugs, percutaneous coronary interventions (PCI) and surgical revascularization (CABG). In our institution the therapeutic decisions for non emergent cases have been regularly taken during a daily meeting attended by clinicians, interventionalists, and surgeons, who all adhere to the principles of Evidence Based Medicine. The purpose of the present report is to investigate the long-term results in a series of consecutive patients to whom surgical revascularization has been recommended following the abovementioned approach.

When should asymptomatic patients with combined severe aortic stenosis and aortic insufficiency undergo valve replacement? A clinical case.

Indications to prosthetic aortic valve implantation in patients with aortic stenosis or aortic regurgitation or both stenotic or regurgitant aortic valve, who present without symptoms, are controversial. We present the case of an asymptomatic patient with combined severe aortic stenosis and an equally important insufficiency, undergoing surgery for valve substitution with a bileaflet prosthesis. After surgery he was treated with warfarin according to the doses recommended and underwent follow-up with clinical and echocardiographic exams.

Evolving standard in the treatment of coronary artery disease. Drug-eluting stents.

Coronary stent implantation is the predominant method of percutaneous coronary interventions (PCI). This is to be attributed to the ease of use beside the better short and long term clinical outcome as compared to balloon angioplasty. Nevertheless, improvements in operator skill and stent technology together with better use of adjunctive pharmacological therapy have contributed to the improvement in clinical outcome.

Drug-eluting stent: the emerging technique for the prevention of restenosis.

Percutaneous coronary interventions (PCI) have surpassed coronary artery bypass grafting as the most common means for treating coronary artery disease, because of materials improvement, the use of stent and pharmacotherapy. However, despite the variety of mechanical techniques such as dilatation, debulking or conventional stent implantation, the incidence of restenosis on short and mid-term follow-up is still representing an important limitation to PCI. Restenosis is mainly due to elastic recoil, negative vessel remodelling and neointimal proliferation, as a response to vessel injury induced by angioplasty devices.

[A case of pulmonary thromboembolism after interruption of treatment with unfractionated heparin].

Pulmonary embolism is a quite frequent event (incidence 1/10000/year), and blood stasis, endothelial lesions and coagulation disorders are predisposable factors. Elective treatment is heparin, but the use of this medication is associated with a possible ipercoagulative rebound effect. The case presented is a patient with unstable angina treated with heparin infusion, who developed pulmonary embolism after discontinuation of heparin treatment; the patient didn't present a genetic coagulopathy.

The role of gastroesophageal reflux disease in chest pain.

Gastroesophageal reflux disease (GERD) is thought to play an important role in the pathogenesis of non-cardiac, unexplained, chest pain. The physiopathological mechanism of this extraesophageal manifestation, remains unclear but it is supposed that the ache could be triggered by the stimulation of acid-sensitive nociceptors of the mucosa. The esophageal origin of the symptom may be identified by an empiric trial of high-dose antisecretory drugs or an abnormal prolonged ambulatory pH monitoring study.

[Surgical treatment of atrial thrombosis. A transesophageal echocardiogram study].

Transesophageal echocardiogram is the procedure of choice in the evaluation of masses located in the cardiac chambers. In this paper three cases of atrial thrombosis are presented: a) a free floating ball thrombus in the left atrium in a patient with moderate mitral stenosis; b) three thrombotic masses adherent to a central venous catheter; c) three thrombotic masses attached to Chiari s network in a patient operated for an ostium secundum atrial septal defect one year before. In all cases transesophageal echocardiogram has played a key role in the diagnosis.

[Gastroesophageal reflux disease and chest pain].

Gastroesophageal reflux disease (GERD) is highly prevalent in the general population. Heartburn and acid regurgitation are considered the typical presentation of GERD, that however might represent a major pathogenic mechanism in patients with chest pain without coronary artery disease. Chest pain in this instance is often successfully treated with high-dose antisecretory drugs, but the pathogenetic mechanism remains unclear.

[Functional assessment of mitral stenosis].

The following parameters must be taken into account when assessing the severity of mitral stenosis: symptoms, objective examination, electrocardiogram, chest X-ray, a simple exercise test with or without cardiopulmonary test, echocardiography and lastly a hemodynamic test. Differences are often observed between the clinical and instrumental findings. In these cases a major contribution is made by the use of physical effort in response to both ECG and heart catheterization in order to quantify the patient's functional deficiency and valve response.

[Ischemic cardiovascular diseases. Correlation with Helicobacter pylori infection].

Coronary heart disease is the primary cause of mortality in western countries. The well-established ("classical") risk factors cannot fully explain epidemiological variations of this disease. From several years infections have been linked to ischemic vascular events and recent studies pointed to the role of Helicobacter pylori (H.

Ischemic cardiovascular disease and Helicobacter pylori. Where is the link?

Coronary heart disease (CHD) is the leading cause of death in western countries. Although several major risk factors have been identified, they fail to account for all the epidemiological variants of the disease, thus warranting research into novel causal agents. Cardiovascular diseases have long been associated with chronic infections acting through the activation of inflammatory pathways, and antibiotic therapy has been shown to produce a dramatic decrease in the rate of disease recurrence in patients with a history of myocardial infarction or unstable angina.
