Early STEMIs may be preceded by peaked T waves. Other ECG abnormalities relating to complications of acute myocardial infarctions may also be evident, such as atrial or ventricular fibrillation. Imaging
Noninvasive imaging plays an important role in the diagnosis and characterisation of myocardial infarction. Tests such as chest X-rays can be used to explore and exclude alternate causes of a persons symptoms. Echocardiography may assist in modifying clinical suspicion of ongoing myocardial infarction in patients that cant be ruled out or ruled in following initial ECG and Troponin testing. Myocardial perfusion imaging has no role in the acute diagnostic algorithm, however it can confirm a clinical suspicion of Chronic Coronary Syndrome when the patients history, physical examination (including cardiac examination) ECG, and cardiac biomarkers suggest coronary artery disease.Echocardiography, an ultrasound scan of the heart, is able to visualize the heart, its size, shape, and any abnormal motion of the heart walls as they beat that may indicate a myocardial infarction. The flow of blood can be imaged, and contrast dyes may be given to improve image. Other scans using radioactive contrast include SPECT CT-scans using thallium, sestamibi (MIBI scans) or tetrofosmin; or a PET scan using Fludeoxyglucose or rubidium-82. These nuclear medicine scans can visualize the perfusion of heart muscle.
Familial nasal acilia is a rare congenital defect which is characterized by the complete absence of cilia on the epithelial cells of the respiratory tract. Symptoms are common within ones family and start as soon as one is born, with signs such as respiratory distress, dyspnea, lobar atelectasis, bronchiectasis and neo-natal pneumonia. Other symptoms that occur later in life include chronic moist coughing, chronic sinusitis, chronic otitis media, chronic rhinitis, and recurrence of upper and lower respiratory tract infections.Exact prevalence is unknown, OrphaNet estimates this condition to affect less than 1 out of every million people worldwide. R Soferman et al. described this disorder to be "autosomal recessive". == References ==
