Thrombolysis with streptokinase during cardiopulmonary resuscitation: a single center experience and review of the literature.
To report our experience with use of thrombolysis with streptokinase during cardiopulmonary resuscitation of patients with cardiac arrest due to myocardial infarction. ⋯ Thrombolysis with streptokinase during cardiopulmonary resuscitation of patients with suspected acute myocardial infarction is associated with reduced mortality and favorable neurological outcome.

Randomized Controlled Trial Multicenter Study Comparative StudyA randomized, double-blind, placebo-controlled study of the safety and efficacy of intravenous MCC-135 as an adjunct to primary percutaneous coronary intervention in patients with acute myocardial infarction: rationale and design of the evaluation of MCC-135 for left ventricular salvage in acute MI (EVOLVE) study.
As a consequence of acute ischemia and reperfusion in patients with acute ST elevation myocardial infarction, calcium overload inside myocytes not only affects myocardial contraction, relaxation, and myocyte recovery following reperfusion, but also may be related to myocyte necrosis and fatal arrhythmia. MCC-135 is the first in a new class of agents that reduce intracellular calcium overload. Pre-clinical and early clinical studies yielded promising results for patients with ST elevation myocardial infarction. ⋯ The rationale, design, and methods of the EVOLVE study are described in this paper, along with 2 sub-studies, involving a comparison of pre- and post-PCI measurements with either SPECT or echocardiography, to examine myocardial salvage and the time course of changes in myocardial infarction size and left ventricular function. MINIABSTRACT: The Evaluation of MCC-135 for Left Ventricular Salvage in Acute MI (EVOLVE) study is a Phase 2, multicenter, randomized, double-blind, placebo-controlled clinical trial of two doses of MCC-135, first in a new class of agents that reduce intracellular calcium overload, as adjunct therapy for preservation of left ventricular function and reduction of infarct size in patients with moderate-large STEMI undergoing primary PCI. The rationale, design, and methods of the EVOLVE study, along with two sub-studies, are described in this paper.

A descriptive evaluation of routine complete blood count monitoring in patients receiving anticoagulation therapy.
The most prevalent side effect associated with warfarin therapy is bleeding. Routine monitoring of laboratory tests, such as complete blood counts (CBC), may provide theoretical benefit in this patient population as a means of detecting occult bleeding through hemoglobin values that decrease compared to baseline. ⋯ Although routine CBC monitoring provides some utility in detecting occult bleeding, the yield of clinically important decreases in hemoglobin detected was low. For most anticoagulated patients, routine CBC monitoring appears to be clinically unnecessary.

The role of exercise on platelet aggregation in patients with stable coronary artery disease: exercise induces aspirin resistant platelet activation.
The aim of our study was to determine the relation between exercise stress test and aspirin resistance in patients with stable coronary artery disease. ⋯ We conclude that 11.1% of in vitro aspirin sensitive subjects at rest had aspirin resistance after exercise by PFA-100. In some individuals, exercise induced platelet activation is aspirin insensitive at usual antiplatelet doses. We need further clinical trials to optimize antiplatelet therapy in patients with coronary artery disease.

Case ReportsLeft atrial free-floating ball thrombus in a case of hyperthrophic cardiomyopathy.
Left atrial free-floating ball thrombus is a rarely seen pathology in the absence or presence of mitral valve disease. This pathologic condition carries high risks of embolic complications and deterioration of hemodynamics. ⋯ Pathologic examination of the mass confirmed the thrombus formation. This rare case of left atrial free floating ball thrombus associated with HCM is presented and current literature is reviewed.
