B E Stähli, U Landmesser
The duration and combination of dual antiplatelet therapy after coronary stent implantation, consisting of aspirin and a P2Y12 inhibitor, is among the most intensely investigated therapeutic strategies in cardiovascular medicine. While initial studies have mainly focused on the efficacy and safety of individual antithrombotic agents, the increased need for a personalized, risk-based approach to define the optimal duration of antithrombotic treatment according to the estimated ischemic and bleeding risk was then recognized...

Out-of-hospital cardiac arrest (OHCA) is a leading cause of death in developed industrial countries. The global worldwide average of OHCA incidence in adults is 95.9/100,000/year. European incidences vary according to source from 16 to 119/100,000/year. The aim of this study was to provide an overview of current information on OHCA. The incidences in various populations are discussed, along with the factors affecting the prognosis and outcome of these patients. The etiology and pathophysiological mechanisms are also described, especially in relation to the most common causes - acute and chronic forms of coronary artery disease and cardiomyopathies...

Psychological stress is thought to be an important trigger of cardiovascular events, yet the involved pathways and mediators are largely unknown. Elevated systemic levels of the pro-inflammatory alarmin S100A8/A9 correlate with poor prognosis in coronary artery disease (CAD) patients. Here, we investigated the links between S100A8/A9 release and parameters of anti-inflammatory glucocorticoid secretion in two different cohorts subjected to a psychological stress test. In the first cohort of 60 CAD patients, psychological stress induced a rapid increase of circulating S100A8/A9...

High-sensitivity C-reactive protein (hs-CRP) is independently associated with cardiovascular events in coronary artery disease (CAD) patients and reducing the hs-CRP level may further benefit this population. We conduct this parallel design, randomized-controlled trial to assess the effectiveness of adjunct sodium tanshinone IIA sulfate (STS) therapy on circulating inflammation markers in CAD patients. Unstable angina or non-ST-elevation myocardial infarction patients with increased hs-CRP level were randomly assigned to atorvastatin-based standard medical therapy or standard therapy plus STS injection (80 mg, once daily for 14 consecutive days)...

Takayasu arteritis is an idiopathic chronic granulomatous panarteritis predominantly affecting the aorta and its main branches. Although idiopathic, genetic contribution to disease susceptibility is being increasingly recognised. Rare in children, Takayasu arteritis is a worldwide disease with significant morbidity and mortality. Its diagnosis is a challenge and requires awareness of the condition as clinical features at presentation are non-specific and assessing disease activity is difficult. In the inflammatory stage, treatment is essential to prevent the insidious course and vascular damage: stenotic, occlusive lesions, aneurysms, and aortic regurgitation...

Cardiac arrhythmia is a common cause of mortality, and its progression may be due to abnormal sympathetic nerve activity and catecholamine release. Besides, lactate dehydrogenase (LDH) and creatine kinase (CK) downregulation and adiponectin expression play important roles in promoting coronary artery disease. The study aimed to examine the possible cardioprotective effect of members of phosphodiesterase type 5 (PDE-5) inhibitors in epinephrine-induced arrhythmia in rats. Arrhythmia was induced by cumulative boluses of epinephrine (4, 8, 16, 32, 64, and 128 mg/kg) given at 10-min intervals...

BACKGROUND AND AIMS: Periodontitis, a common polymicrobial inflammatory disease in the tooth supporting tissues, is a risk factor for coronary artery disease. One of the proposed underlying mechanisms is the systemic immune response to periodontal infection. We studied how serum antibodies against seven periodontal pathogens and their subgingival levels associate with each other, periodontitis, and coronary artery disease. METHODS: The Parogene cohort included 505 Finnish patients (mean age 63 y) who underwent coronary angiography, and clinical and radiographic oral examinations...

A 66-year-old man with poorly controlled type 2 diabetes was admitted for acute bilateral calf pain in the context of coronary artery disease, chronic renal failure, and peripheral neuropathy. Lower-extremity Doppler ultrasound excluded deep vein thrombosis. FDG-PET was performed to exclude a suspected infection because of elevated white blood cells and inflammatory markers but normal creatinine kinase levels. PET scan demonstrated intense bilateral calf muscle and left thigh muscle uptake, which in combination with the patient's history was consistent with diabetic myonecrosis, a rare end-stage complication of diabetes...

Erosive pustular dermatosis of the scalp (EPDS) is an inflammatory dermatosis of unknown etiology. Herein, we present a review of the disease and report our own clinical and histopathological experience in eleven patients. EPDS tends to spontaneously affect bald areas of the scalp in elderly individuals. A history of previous surgery at the same site - as observed in four of our patients - is common. Coronary artery disease, cerebrovascular insult, arterial hypertension, diabetes mellitus, and severe cases of cancer were frequent comorbidities...

The crucial issues in optimal medical therapy to improve prognosis and reduce angina symptoms are secondary prevention, effective control of concomitant diseases, risk factors and medical treatment. In spite of successful percutaneous coronary interventions (PCI) and medical treatment with beta-blockers, ACE-inhibitors or angiotensin receptor blockers, statins and antiplatelet drugs, some patients are still symptomatic. In the era of PCI not sufficient attention is paid to other drugs reducing the incidence of angina episodes: calcium antagonists, long-acting nitrates, metabolic agents and novel antianginal drugs...

R Y Song, R T Ding, W Cui
Sudden cardiac death (SCD), most commonly seen in coronary heart disease, is a kind of sudden death caused by series of cardiac parameters, which usually combines with myocardial infarction. However, some SCDs (including early myocardial infarction) happen suddenly and cause death in a very short time. In these circumstances, typical morphological changes are lack in macroscopic or microscopic fields, which make such SCDs become the emphasis and difficulty in the present research. SCD caused by myocardial infarction and abnormalities of cardiac conduction system (CCS) is related to atherosclerosis of coronary artery closely...

Myocardial perfusion-single-photon emission computed tomography (MP-SPECT) is used to evaluate microvascular dysfunction and coexisting coronary artery disease in patients with hypertrophic cardiomyopathy (HCM). Phase analysis in gated MP-SPECT can provide additional information on left ventricular (LV) dyssynchrony, while the extent of late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) imaging is an important prognostic factor in patients with HCM. We, therefore, sought to investigate the relationship of dyssynchrony by phase analysis on gated MP-SPECT and LGE on CMR imaging in 22 patients with HCM who underwent both stress/rest-gated MP-SPECT and contrast-enhanced CMR imaging...

Several modifiable factors may influence cardiac function in diabetic patients. The aim of the study was to evaluate the influence of vitamin D level on the stage of coronary atherosclerosis in cardiac patients diagnosed with type 2 diabetes. The study was performed in 337 consecutive patients undergoing coronarography. The stage of atherosclerosis was evaluated using Coronary Artery Surgery Study Score. The plasma 25(OH)D concentration was determined by an electrochemiluminescence method. Patients without significant lesions in coronary arteries presented the highest 25(OH)D level, significantly higher than patients with one-, two-, and three-vessel coronary artery disease (CAD) (p < 0...
