Coronary artery anomalies are often discovered incidentally during cardiac catheterization or computed tomography coronary angiography and may involve the affected coronary artery origin and its course. Coronary artery anomalies are associated with congenital heart disease. The affected coronary arteries may have an unusual high take off origin, origin from contralateral or non-coronary sinus, origin from the pulmonary artery, single coronary system or coronary artery fistula.

It is known fact that diabetes mellitus (DM) affects blood cells. Changes in the erythrocyte membrane, disorder in hemoglobin oxygen-binding and modification in mechanical characteristics, are effects of hyperglycemia on red blood cells. Altered susceptibility infection of patients with diabetes has been ascribed to a depression in the function of polymorphonuclear leukocytes. Neutrophil function in case of patients with diabetes with good glucose control is slightly different than in the case of healthy ones...

The hematocrit (Hct) determines the oxygen carrying capacity of blood, but also increases blood viscosity and thus flow resistance. From this dual role the concept of an optimum Hct for tissue oxygenation has been derived. Viscometric studies using the ratio Hct/blood viscosity at high shear rate showed an optimum Hct of 50-60% for red blood cell (RBC) suspensions in plasma. For the perfusion of an artificial microvascular network with 5-70μm channels the optimum Hct was 60-70% for high driving pressures. With lower shear rates or driving pressures the optimum Hct shifted towards lower values...

OBJECTIVES: To identify unique echocardiographic features that could be used to reliably predict LVEF recovery upon resolution of sinus tachycardia in patients with cancer. BACKGROUND: Sinus tachycardia may be a manifestation of underlying cardiomyopathy or can lead to a reversible form of dilated cardiomyopathy known as tachycardia-mediated cardiomyopathy. While distinguishing the two can be challenging, predicting recovery regardless of cause can be of significant clinical importance in the cancer population...

A 45 yrs male presented with angina. ECG showed transient CHB, T wave inversion in V3 to V6 and inferior leads. It was difficult to predict the culprit vessel based on ECG. Coronary angiography showed thrombotic lesions in LAD, LCX and OM which can potentially impact identification of culprit vessel and hence affect the management with primary PCI.

INTRODUCTION: Cardiovascular diseases are becoming the major cause of morbidity and mortality in most of the developing countries including India. Cardiometabolic risk factors play a vital role in causation of coronary artery disease. Present study was carried out to investigate the role of various risk factors in the occurrence of coronary artery disease (CAD) in population from Central India. SETTING AND DESIGN: This was a hospital-based age and sex matched case-control study, carried out at Lata Mangeshkar Hospital, Nagpur...

The mouse is the second mammalian species, after the human, in which substantial amount of the genomic information has been analyzed. With advances in transgenic technology, mutagenesis is now much easier to carry out in mice. Consequently, an increasing number of transgenic mouse systems have been generated for the study of cardiac arrhythmias in ion channelopathies and cardiomyopathies. Mouse hearts are also amenable to physical manipulation such as coronary artery ligation and transverse aortic constriction to induce heart failure, radiofrequency ablation of the AV node to model complete AV block and even implantation of a miniature pacemaker to induce cardiac dyssynchrony...

Acute coronary syndrome (ACS) is a cardiovascular condition with a multifactorial pathophysiology that includes atherosclerotic plaques, platelet activation and thrombin production, among others. Thrombin production and the prothrombotic state of ACS patients have provided a role for anticoagulants to treat patients during the acute event and has led to subsequent research for the post-acute state. Warfarin has an indication for ACS, however, it is restricted to specific patients and many factors limit its use...

OBJECTIVE: To observe the effects of sympathetic overactivity on the immune system involved in the imbalance of T helper (Th) lymphocytes, we investigated the correlation between autonomic dysregulation and the generation of regulatory T (Treg) and Th1 chemokines in patients with acute coronary syndrome (ACS). METHODS: Blood samples obtained from patients with coronary artery disease and controls were analyzed for levels of Th1 and Treg cells and their associated cytokines by flow cytometry...

A 29 year male, with an inoperable adenocarcinoma of gall bladder was initiated on gemcitabine and a platinum compound based chemotherapy. During 4th cycle of chemotherapy, patient complained of chest pain following cisplatin and gemcitabine infusion. ECG was suggestive of acute coronary syndrome, which was successfully managed by antianginal therapy. Fifth cycle of chemotherapy was uneventful. Patient died of cardiovascular collapse before receiving the 6th cycle of chemotherapy. As per Naranjo adverse drug reaction probability scale, causal association of the event with cisplatin and gemcitabine was probable and possible respectively...

The concept of the 'vulnerable plaque' originated from pathological observations in patients who died from acute coronary syndrome. This recognition spawned a generation of research that led to greater understanding of how complicated atherosclerotic plaques form and precipitate thrombotic events. In current practice, an increasing number of patients who survive their first event present with non-ST-segment elevation myocardial infarction (NSTEMI) rather than myocardial infarction (MI) with ST-segment elevation (STEMI)...

Ticagrelor has been endorsed by guidelines as the P2Y12 inhibitor of choice in patients with acute coronary syndrome. Clinically, some patients on ticagrelor will require a switch to clopidogrel; however, the optimal strategy and pharmacodynamics effects of switching remain unknown. Patients with an indication to switch were randomly assigned to either a bolus arm (Clopidogrel 600 mg bolus followed by 75 mg daily, n=30) or a no-bolus arm (Clopidogrel 75 mg daily, n=30). Blood samples were collected at baseline, 12, 24, 48, 54, 60 and 72 hours (h) for assessment of platelet reactivity...

BACKGROUND: Kawasaki disease (KD) is the most common cause of acquired myocardial infarction in children. Coronary artery involvement is the most serious feature of this vasculitis syndrome. Timely diagnosis of coronary artery involvement is of utmost importance since it can prevent long-term morbidity and mortality. The current methods for the diagnosis of coronary artery dilation in KD are inconsistent and are also not capable of detecting all the abnormal coronary arteries or the so-called occult dilations present...

Sudden cardiac death (SCD) is a rare but devastating complication of a number of underlying cardiovascular diseases. While coronary artery disease and acute myocardial infarction are the most common causes of SCD in older populations, inherited cardiac disorders comprise a substantial proportion of SCD cases aged less than 40 years. Inherited cardiac disorders include primary inherited arrhythmogenic disorders such as familial long QT syndrome (LQTS), Brugada syndrome (BrS), catecholaminergic polymorphic ventricular tachycardia (CPVT), and inherited cardiomyopathies, most commonly hypertrophic cardiomyopathy (HCM)...

BACKGROUND: Thromboembolic complications are the main problem in stent-assisted coil embolization of unruptured intracranial aneurysms. The combination of aspirin and clopidogrel is generally used to decrease these complications, but some patients do not respond to clopidogrel and have a higher risk of stent thrombosis. In cardiology, clinical trials have shown that prasugrel reduced the incidence of ischaemic events in patients with acute coronary syndrome compared with clopidogrel but, according to several authors, prasugrel would produce an increased risk of cerebral haemorrhagic complications...

BACKGROUND: In patients undergoing cardiac surgery, a reduced preoperative left ventricular ejection fraction (LVEF) is common and is associated with a worse outcome. Available outcome data for these patients address specific surgical procedures, mainly coronary artery bypass graft (CABG). Aim of our study was to investigate perioperative outcome of surgery on patients with low pre-operative LVEF undergoing a broad range of cardiac surgical procedures. METHODS: Data from patients with pre-operative LVEF ≤40 % undergoing cardiac surgery at a university hospital were reviewed and analyzed...
