Abstract Introduction Cardiac arrest secondary to a spontaneous coronary artery dissection (SCAD) represents challenging scenario. It deserves specific considerations due the dramatic presentation and need for sudden cardiac death prevention. Methods We collected clinical data of four women admitted during last two years in Coronary Care Unit Parma University Hospital, whose SCAD were ventricul...

After its inception in Koenker and Bassett (1978), quantile regression has become an important and widely used technique to study the whole conditional distribution of a response variable and grown into an important tool of applied statistics over the last three decades. In this work, we focus on the variable selection aspect of penalized quantile regression. Under some mild conditions, we demo...

Spontaneous coronary artery dissection (SCAD) is gaining recognition as an important cause of myocardial infarction, especially in young women. There has been a surge in the diagnosis of SCAD in recent years, presumably due to an increased use of coronary angiography, and the clinical availability and application of high-resolution intracoronary imaging. The improved recognition and diagnosis, ...

Spontaneous coronary artery dissection (SCAD) is a rare and important cause of acute coronary syndrome and sudden cardiac death. Various etiologies are thought to be responsible for this condition, among which underlying atherosclerosis seems to be the most common. SCAD is predominant in women and is usually diagnosed via coronary artery angiography. Therapeutic interventions include medical th...

Spontaneous coronary artery dissection SCAD is a rare condition which may result in sudden coronary occlusion, acute myocardial infarction and sudden cardiac death. The prognosis of spontaneous coronary artery dissection is uncertain and optimal treatment is unknown. We describe a case of SCAD in a 29-year-old male with acute inferior wall myocardial infarction MI and post-MI angina that was tr...

Estimating the images using decimated wavelet transform is very popular technique in different applications. In this paper a new thresholding function with combination of Smoothly Clipped Absolute Deviation (SCAD), Hard thresholding and soft thresholding functions are introduced for wavelet based denoising of images. The proposed technique is applied for denoising of noisy images contaminated w...

This paper extends the adaptive LASSO (ALASSO) for simultaneous parameter estimation and variable selection to a varying-coefficient partially linear model where some of the covariates are subject to measurement errors of an additive form. We draw comparisons with the SCAD, and prove that both the ALASSO and SCAD attain the oracle property under this setup. We further develop an algorithm in th...

Spontaneous coronary artery dissection (SCAD) is a very rare disease, associated with high mortality rate, whose etiology and pathogenesis are poorly understood. Its sporadic nature and the varied angiographic extent make firm recommendations regarding revascularization impossible. The case described is that of a young, otherwise healthy woman, without a known underlying condition which may lea...
