Active clinical trials for "Calcinosis"

The aim of the study was to determine retrospectively the presence of carotid artery calcification (CAC) detected on digital panoramic radiographs (DPRs) and correlate the finding of such calcifications with gender, smoking status, medical history and periodontal status.The authors hypothesized that more CACs could observed in DPRs of individuals with periodontitis and CACs may correlate with the various risk factors included age, gender, smoking status, medical history.DPRs, periodontal status, medical (hypertension, diabetes, hyperlipidemia, cardiovascular disease) and smoking stories of 1101 patients (576 males, 525 females) were evaluated. The patients were divided into two groups as CAC detected in dental DPRs [CAC(+)] and those who were not [CAC (-)]. Periodontal status categorized as gingivitis, periodontitis and gingivitis with reduced periodontium.

The IVL-Dragon Registry was a multicenter study that enrolled consecutive patients with stent underexpansion treated with IVL in high-volume PCI centers. The primary efficacy endpoint was clinical success, defined as a reduction of stent underexpansion to <30% with no evidence of in-hospital device-oriented composite end point (DOCE) (defined as a composite of cardiac death, target lesion revascularization, and target vessel myocardial infarction).

The following trial hypothesis will be proved: In patients with atrial fibrillation and/ or pulmonary embolism standard anticoagulant treatment with coumadin/phenprocoumon is associated with accelerated coronary or valvular calcification as assessed by cardiac computed tomography compared to the new anticoagulant therapy with rivaroxaban.

Radiography of breast specimens is currently the only radiological procedure used to verify removal of microcalcifications and presence of tumor-free margins after breast surgical resection. Ex vivo MRI will be tested for its ability to detect residual tumor tissue not detected by radiography in resected breast tumor specimens and/or its ability to verify tumor-free margins in breast cancer detected by MRI only.

The aortic valve is the main outlet valve from the heart. This valve can become diseased and narrowed when it needs to be replaced with an artificial valve. Currently, this is the commonest reason for someone to undergo a heart valve operation in the UK. Unfortunately, there are no medical treatments that can prevent or delay the progression of this disease process. Here, the investigators propose to use new state-of-the-art imaging techniques to better understand the disease process so that the investigators can effectively design and assess potential new treatments. The ultimate aim is to stop this disease before patients need to have surgery. In addition the investigators believe this technique will allow us to predict the rate of progression of the disease

Background: Generalized Arterial Calcification of Infancy (GACI) is a very rare disorder. It can be fatal before birth or by age 6 months. Anumber of people with GACI survive into adulthood. Those adults suffer from side effects of the disease, including rickets. It is unknown how common the disease Autosomal Recessive Hypophosphatemic Rickets Type 2 (ARHR2) is. It also has side effects. GACI and ARHR2 are usually caused by the mutations in the same gene. There are no approved treatments for the two diseases. Researchers want to study people with these diseases and their family members. This may help understand these rare and unique diseases better. The data could lead to new treatments for GACI and ARHR2. Objectives: To better understand the progression of GACI and ARHR2 and how genes might play a role in them. Eligibility: People with GACI or ARHR2, both living and deceased, and their parents and siblings. Design: Participants will allow researchers to access their medical records. They will give this consent by mail, email, or fax. Data will be taken from the records. Participants names will not be used. Instead, they will be identified by a code. Participants may give a blood sample. If a participant withdraws from the study, their data and samples will be destroyed. However, the coded clinical data in the official medical record and data in databases will NOT be destroyed. ...

To define the correlation of the levels of a-Klotho with the severity of vascular calcification in the coronary arteries and aortic valve.

Aim of the work : 1. Using different calcification scoring systems to investigate the association between arterial calcification and clinical outcome following endovascular therapy

This study aim to observe the preventive effect and the long term safety of low calcium dialysis on coronary artery calcification in Maintenance hemodialysis (MHD) patients.

Coronary artery disease (CAD) is an important health concern for African Americans, who are diagnosed with CAD at high rates. Coronary artery calcification, which is characterized by calcium deposits in the coronary arteries, is a contributing factor to CAD. This study will examine the possible genetic causes of coronary artery calcification in African Americans.
