Atrial Transcriptional Profiles of Molecular Targets Mediating Electrophysiological Function in Aging and Pgc-1 β Deficient Murine Hearts
Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health pro...

Long-term risk of rosiglitazone on cardiovascular events: a systematic review and meta-analysis.
Abstract Rosiglitazone has been proposed as a treatment strategy for type 2 diabetes mellitus (T2DM), could provide robust glucose-lowering capability with risk of cardiovascular events. We thus did a systematic review and meta-analysis of controlled trials to assess the effect of this treatment on glycaemic control, cardiovascular events in patients with T2DM. We systematically search PubMed, Embase and Cochrane Central Register of Controlled Trials comparing rosiglitazone to other anti-diabetic treatments. These studies included randomized controlled trials (RCTs), cohort studies, and case-control studies that h...

Antidiabetic drugs and stroke risk. Current evidence.
Abstract Cardiovascular disease (CVD) is the major cause of morbidity and mortality for individuals with type 2 diabetes (T2D). In particular, the risk for stroke is twice that of patients without diabetes, and diabetes may be responsible for >8% of first ischemic strokes. Therefore, the way to prevent stroke in these patients has become an important issue. Traditionally, glucose-lowering drugs had not been shown to protect against stroke. Moreover, several antidiabetic drugs (i.e., sulfonylureas, rosiglitazone) have been reported to be associated with increased risks of CVD and stroke. On the contrary, data on...

Cardiovascular benefits and safety of non-insulin medications used in the treatment of type 2 diabetes mellitus.
Authors: Yandrapalli S, Jolly G, Horblitt A, Sanaani A, Aronow WS Abstract Diabetes mellitus is a growing in exponential proportions. If the current growth trend continues, it may result in every third adult in the United States having diabetes mellitus by 2050, and every 10(th) adult worldwide. Type 2 diabetes mellitus (T2DM) confers a 2- to 3-fold increased risk of cardiovascular (CV) events compared with non-diabetic patients, and CV mortality is responsible for around 80% mortality in this population. Patients with T2DM can have other features of insulin resistance-metabolic syndrome like hypertension, lipid ab...

Abstract 013: Using the Diabetes Collaborative Registry (DCR) to Estimate the Potential Real-world Impact of the Iris Trial on Improving Outcomes in Patients With Cerebrovascular Disease Session Title: Poster Session I
Conclusion: In a large US-based outpatient registry, we found that 12% of outpatients with prediabetes or diet-controlled T2D met the main eligibility criteria for IRIS, partly due to the narrow inclusion criteria of the trial but also likely reflective of a general paucity of screening for prediabetes and insulin resistance in this cohort. Pioglitazone was rarely used in these patients but could have a substantial impact on CV outcomes in these eligible patients. The population impact could be even greater if the CV benefit of pioglitazone can be demonstrated in patients with cerebrovascular disease and overt T2D or even ...

Antidiabetic agents and cardiovascular outcomes in patients with heart diseases.
This article reviews evidence of benefits and risk of antidiabetic agents in cardiovascular (CV) outcomes, with a focus on medications approved by the FDA since 2008. Peer-reviewed articles were identified from MEDLINE and Current Content database (both 1966 to October 1, 2016) using the search terms insulin, metformin, rosiglitazone, pioglitazone, glyburide, glipizide, glimepiride, acarbose, miglitol, albiglutide, exenatide, liraglutide, lixisenatide, dulaglutide, pramlintide, meglitinide, alogliptin, linagliptin, saxagliptin, sitagliptin, canagliflozin, dapagliflozin, empagliflozin, colesevalam, bromocriptine, mortality,...

Expensive New Diabetes Drugs Add Nothing But Cost And Complications
This is the fourth in an ongoing series of blogs exposing the rampant misuse of the medications so aggressively promoted by greedy drug companies. I am very lucky in having the perfect partner in this truth-vs-power effort to contradict Pharma propaganda with evidence based fact. Dick Bijl is President of the International Society of Drug Bulletins (ISDB), an impressive association of 53 national drug bulletins from all around the world, each of which publishes the best available data on the pluses and minuses of different medications. Drug bulletins help patients and doctors see through the misleading misinformation ge...

3 Drugs with the Most Severe Side Effects
Image Source Drugs have been known to have some sort of side effects on patients. Most of them are not often discussed in the health tabloids. While other drugs have side effects that are very nominal when compared to the benefits the patient derives from their usage, others have side effects that can impact the lives of their users forever. The most common side effects people experience from drug usage are gastrointestinal related issues which include constipation, nausea, and vomiting. Some other drugs can leave you feeling tired and dizzy for a short period of time. Combining these drugs with simple aspirin will usuall...

Rosiglitazone and Outcomes for Patients with Diabetes and Coronary Artery Disease in the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) Trial.
CONCLUSIONS: Among patients with type 2 diabetes and CAD in the BARI 2D trial, neither on-treatment nor propensity matched analysis supported an association of rosiglitazone treatment with an increase in major ischemic cardiovascular events.

Families face battle with GSK over dangerous diabetes drug
Exclusive: Pharmaceutical giant resists claims despite settlement with victims in USThousands of families in the UK could be deprived of compensation for the death or harm of a relative caused by the diabetes drug Avandia, even though the British maker has agreed to pay billions of dollars to settle similar claims in the US.The licence for Avandia was revoked in Europe, in September 2010, because of evidence that it could cause heart failure and heart attacks. The drug can still be prescribed in the US, but not to patients at risk of heart problems.A scientist with the Food and Drug Administration estimated that Avandia co...
