Over the centuries, opium has been the most frequent substance abused in the Middle East. There are many controversial aspects about the effects of opioids on the atherosclerosis process, which is still unclear. ⋯ Our investigations demonstrate that opium is not cardioprotective, as has been claimed by some previous studies, and does not even decelerate atherosclerosis of carotid arteries in opium-addicted patients, but more evidence is still needed to completely prove the case.

Clinical implication of gastrointestinal bleeding in degenerative aortic stenosis: an update.
Gastrointestinal (GI) bleeding due to colonic angiodysplasias can be associated with calcifying aortic stenosis (AS). GI angiodysplasias and AS are defined as chronic degenerative disorders, and the prevalence of both diseases increases with age. ⋯ Aortic valve replacement is the first line therapy for advanced stage AS-patients, but can also be an effective treatment for co-existent bleeding angiodysplasias and acquired von Willebrand disease. In this study, we tried to collect as well as systemized data about the etiopathogenesis of AS coagulation abnormalities and diagnostic, clinical and therapeutic implications of AS-patient with GI angiodysplasias.

Intoxication caused by propafenone is very rare, and there are no known detailed epidemiological studies. We present the clinical manifestation of severe propafenone intoxication,successfully treated in a 17 year-old male. He was brought to the Intensive Care Unit after he had taken 3.0 g propafenone. ⋯ Cessation of toxic signs four hours after admission to hospital was observed. This relatively rare, fully symptomatic intoxication with propafenone deserved to be presented due to the drug's common usage in the treatment of dysrhythmia and life-threatening symptoms of overdosing. The course of the disease was dramatic and the patient survived only thanks to quick resuscitation, artificial ventilation, transient heart pacing, acidosis treatment and administration of pressure doses of catecholamines.

Information is limited regarding the knowledge and attitudes of physicians typically involved in the referral of patients for implantable cardioverter-defibrillator (ICD) implantation. ⋯ A lack of familiarity with current clinical guidelines regarding ICD implantation exists. Primary care physicians are less aware of clinical guidelines than are cardiologists. This finding highlights the need to improve the dissemination of guidelines to primary care physicians in an effort to improve ICD utilization.

Plasma cardiac troponins (cTn) are frequently elevated in acute pulmonary embolism (APE). ST-segment abnormalities on electrocardiography are also commonly observed in APE patients. However, it has not been defined which ventricle is a potential source of cTn release. We assessed the potential relationship between electrocardiographic signs of myocardial ischemia, systolic dysfunction of both ventricles at echocardiography and cTn levels in APE. ⋯ Signs of myocardial ischemia (ST-segment changes) on electrocardiography in APE correlate with an elevated cTn and with the impairment of right, but not left, ventricle systolic function at echocardiography.
