Cardiovascular diseases are the first cause of death in developed countries. Using electrocardiographic (ECG), blood pressure (BP) and respiratory flow signals, we obtained parameters for classifying cardiomyopathy patients. 42 patients with ischemic (ICM) and dilated (DCM) cardiomyopathies were studied. The left ventricular ejection fraction (LVEF) was used to stratify patients with low risk (LR: LVEF>35%, 14 patients) and high risk (HR: LVEF≤ 35%, 28 patients) of heart attack. RR, SBP and TTot time series were extracted from the ECG, BP and respiratory flow signals, respectively...

The continuing advances in the biochemical research for the discovering an ideal biomarker for diagnosing myocardial injury have led to discovery cardiac Troponin, a biochemical gold standard for myocardial necrosis. Further with advances in the immunoassay techniques, the 99th percentile cutoff value of cardiac troponin required for the diagnosis of myocardial infarction decreased, with the latest available ultrasensitive cardiac troponin assay capable of measuring level as low as 0.005 ng/ml. Troponin have both diagnostic as well as prognostic significance in myocardial necrosis, but the cut off value by 99th percentile rule is useful only when applied to patients with a high pretest probability of Acute Coronary Syndrome(ACS) and also the results must be interpreted in the context of clinical history, ECG findings, and possibly cardiac imaging to establish the correct diagnosis...

Takotsubo cardiomyopaty is a recently described syndrome characterized by transient left ventricular dysfunction, mimicking an acute coronary syndrome and usually precipitated by a physical or emotional stress. We report the first case of Takotsubo cardiomyopathy after acute diarrhea in a man. It may be argued that severe diarrhea in predisposed individuals may cause an acute stress resulting in increased sympathetic activity leading to this syndrome. Probably the relationship between the adrenergic system and the heart is more complex than general thought and the stimuli which favor an autonomic imbalance and precipitate the syndrome are very disparate in clinical practice...

Inheritance plays an important role in the cardiomyopathies (i.e. dysfunction of the cardiac muscle of unknown origin). This especially has become obvious for the entity asymmetric septal hypertrophy of autosomal dominant inheritance (ASH), a cardiomyopaty with and without obstruction. But this is not the only type of cardiomyopathy of dominant transmittance as was shown by the demonstration of a kindred, in which echocardiographically no hypertrophy of the septum could be found. For it was not possible to find a uniformity for all the affected members of the kindred, for example a congestive course of the disease...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
