| | Coronary artery bypass surgery is widely used to restore adequate blood flow to the heart muscle beyond severe atheromatous obstruction in the main coronary arteries. | | | They are used for dilation of a partly obstructed coronary artery (percutaneous transluminal coronary angioplasty, or PTCA), with restoration of blood flow to the heart muscle, and of a severely obstructed heart valve, particularly the aortic valve, relieving the pressure on the left ventricle. | | | The use of closed-chest cardiopulmonary massage (massage of heart and lungs without making an opening in the chest wall), coupled with electrical defibrillation (the use of electrical shocks), if applied within a few minutes of the sudden death episode, may successfully resuscitate the majority of patients. |

| | Postgraduate Medicine: Initial appraisal of acute coronary syndrome |
| | Acute coronary chest pain syndromes are due to coronary vessel obstruction and thrombotic occlusion. | | | However, if noninvasive means of obtaining high-quality coronary visualization, such as magnetic resonance coronary angiography (37), become available, then this might become an important approach to assigning risk and directing triage to subsequent invasive radiographic angiography and interventional therapy. | | | Accurate diagnosis of acute coronary syndrome should begin with careful history taking and physical examination, with particular emphasis on categorization of a patient's level of risk. |

| | The haemodynamic effects of coronary artery occlusion were similar in control (sham operated) and paced dogs and are summarized in Table 2. | | | The incidences of VT (56%) and of VF (33%) during the occlusion period were not significantly different to the sham controls (75 and 58%, respectively) and somewhat higher than in the paced dogs that had not been given aminoguanidine (incidences of VT and VF 46 and 15%, respectively). | | | For example, only two of the paced dogs succumbed in ventricular fibrillation during the occlusion period; this incidence of VF during occlusion (15%) is similar to that observed by Kaszala et al. |
