Acute myocardial infarction following a hornet sting.

Background: The occurrence of an acute myocardial infarction following a hornet sting has been very rarely reported in the previous literature. Pathogenetic mechanisms include direct action of the venom components on the coronary endothelium and allergic reaction with mediators released from mast cells. The anaphylactic reaction and venom components can produce acute coronary artery thrombosis.

[Nonoclusive thrombosis of mechanical mitral valve prosthesis caused by inadequate treatment of anticoagulant therapy resistance].

Unlabelled: BACKGROUND; Oral anticoagulants have been used in the prevention of thromboembolic complications for over six decades. A rare, but possible problem in the application of these medications could be resistance to them.

Case Report: We presented a patient with nonocclusive thrombosis of the mechanical mitral prosthesis due to inadequately treated resistance to peroral anticoagulant therapy.

[Clinical manifestations of familial hypercholesterolemia].

Familial hypercholesterolaemia (FH) is an autosomal-dominant inherited disorder clinically characterized by high serum cholesterol (low-density lipoprotein--LDL-fraction) concentrations, xanthomas and premature atherosclerosis. Homozygous individuals suffer from vascular disease in childhood or young adolescence since heterozygous persons are usually at ligh risk of premature cardiovascular death. We present a 42-year old female with coronary heart disease and tuber and tendinous xanthomas, which appeared as a consequence of delayed diagnosis of familial hypercholesterolaemia.

[Isolated systolic arterial hypertension in the elderly].

Isolated systolic hypertension is a common disorder in the elderly carrying a high risk of stroke and cardiovascular disease. Isolated systolic hypertension is usually defined as a systolic blood pressure greater than or equal to 160 mmHg and diastolic blood pressure less than 95 mmHg. The arterial stiffening is the principal cause of increasing systolic pressure in advanced age.
