A change from atrial fibrillation into a wide QRS tachycardia in a 69-year-old man

A 69-year-old man experienced a myocardial infarction 2 years ago and was treated for heart failure (left ventricular ejection fraction 40%) with an angiotensin-converting enzyme inhibitor, a beta-blocking agent, a statin, and a diuretic. He presented to the hospital because of symptoms of palpitations accompanied by shortness of breath. At that time, the ECG shown in Figure  1A was recorded. Figure 1B shows sinus rhythm after electric cardioversion of both tachycardias.

For decades, doctors have known that losing weight can significantly lower risk of heart disease and by extension, reduce the risk of dying from heart-related events such as stroke and heart attack. Studies have shown that both lifestyle changes including diet and exercise as well as medications and weight-loss surgery can improve heart disease risk factors such as obesity and diabetes, for example, but data supporting the benefits of any of these approaches in actually lowering rates of heart events such as heart attack and atrial fibrillation, or in reducing early deaths from heart disease, have been less robust. The dat...

This study investigated if statins would similarly reduce postoperative arrhythmias in patients undergoing THA. METHODS:: We queried a large Medicare and private-payer database from 2005 to 2012 and identified 12,075 patients who were on a statin prior to THA. We then age and sex matched 34,446 non-statin users who underwent THA. Baseline comorbidities and postoperative complications were obtained and assessed via standard descriptive statistics. RESULTS:: The statin users had more preoperative comorbidities including congestive heart failure, valvular heart disease, pulmonary and renal disease, diabetes, hyperte...

Abstract Background -Current strategies for cardiovascular disease (CVD) risk assessment among adults without known CVD are limited by suboptimal performance and a narrow focus on only atherosclerotic CVD (ASCVD). We hypothesized that a strategy combining promising biomarkers across multiple different testing modalities would improve global and atherosclerotic CVD risk assessment among individuals without known CVD. Methods -We included participants from the Multi-Ethnic Study of Atherosclerosis (MESA, n=6621) and Dallas Heart Study (DHS, n=2202) who were free from CVD and underwent measurement of left ventricular...

BackgroundAlthough the rate of in‐hospital ischemic events after myocardial infarction (MI) has dramatically decreased, long‐term residual risk may remain substantial. However, most of the information on current residual risk is derived from highly selected randomized trials. HypothesisIn patients with previous MI and no prior ischemic stroke/transient ischemic attack (TIA), residual ischemic risk increases over time. MethodsUsing the international Reduction of Atherothrombosis for Continued Health (REACH) registry, we analyzed baseline characteristics and 4‐year follow‐up of patients with previous MI and no histor...

Conclusions Among older adults discharged alive after ACS hospitalization, we found no significant difference in cardiovascular outcomes or serious, infrequent side effects in patients prescribed generic atorvastatin compared with those prescribed Lipitor® at 1 year. Our findings support the use of generic atorvastatin in ACS, which could lead to substantial cost saving for patients and health care plans without diminishing population clinical effectiveness.

Conclusions— TIA patients with high estimated ischemic stroke risk are less likely to receive defect-free care than low-risk patients. Standardized risk assessment and delivery of optimal inpatient care are needed to reduce this risk-treatment mismatch.

This study was designed to examine whether valsartan or fluvastatin can reduce the risk of non-permanent AF in patients with hypertension.Methods/designThe VF-HT-AF study is a multicenter, randomized, open-label, four-arm parallel group study with comparative evaluation of valsartan and fluvastatin as upstream therapies for the treatment of non-permanent AF complicated by hypertension. The primary outcome measure is change in the development of paroxysmal AF into persistent or permanent AF, the development of persistent AF to permanent AF, and change in incidence of overall and persistent AF recurrence, as evaluated by 7-d...
