The branching characteristics of the right coronary artery, acute marginal, posterior descending, left anterior descending, circumflex, and obtuse marginal arteries are compared with those of diagonal branches, left and right ventricular branches, septal, and higher-order branches, to test a newly proposed functional classification of the coronary arteries in which the first group rank as distributing vessels and the second as delivering vessels. According to this classification, the function of the first type is merely to convey blood to the borders of myocardial zones, while the function of

To establish a mathematical model of the tree like arteries for the purpose of hemodynamic analysis, a complete set of morphometric data of pig coronary arteries is presented. For the purpose of mathematical modeling, three innovations in morphometry are introduced: 1) a rule for assigning the order numbers of the vessels on the basis of diameter ranges, 2) a connectivity matrix to describe asymmetric branching, and 3) a measurement of the fraction of vessel segments connected in series. The morphometric measurements were made with the silicone elastomer-casting method. Data on smaller vessels

The heart muscle is nourished by a complex system of blood vessels that make up the coronary circulation. Here we show that the design of the coronary circulation has a functional hierarchy. A full anatomic model of the coronary arterial tree, containing millions of blood vessels down to the capillary vessels, was simulated based on previously measured porcine morphometric data. A network analysis of blood flow through every vessel segment was carried out based on the laws of fluid mechanics and appropriate boundary conditions. Our results show an abrupt change in cross-sectional area that dem

The blood vessels that run on the surface of the heart and through its muscle are compliant tubes that can be affected by the pressures external to them in at least two ways. If the pressure outside these vessels is higher than the pressure at their downstream ends, the vessels may collapse and become Starling resistors or vascular waterfalls. If this happens, the flow through these vessels depends on their resistance and the pressure drop from their inflow to the pressure around them and is independent of the actual downstream pressure.

Background: Recent discoveries have indicated that, in the developing heart, sinus venosus and endocardium provide major sources of endothelium for coronary vessel growth that supports the expanding myocardium. Here we set out to study the origin of the coronary vessels that develop in response to vascular endothelial growth factor B (VEGF-B) in the heart and the effect of VEGF-B on recovery from myocardial infarction. Methods: We used mice and rats expressing a VEGF-B transgene, VEGF-B-gene–deleted mice and rats, apelin-CreERT, and natriuretic peptide receptor 3–CreERT recombinase-mediated ge

Given that circulating ET levels in heart failure, in particular, may reach physiological threshold for coronary constrictor responses, the primary objective of the present review is to consider coronary vessels as an important target for circulating and locally produced endothelin(s). In healthy vessels, ET-1 causes biphasic coronary responses characterized by a transient dilation of large and small arteries followed by a sustained constriction. ETB receptors are pivotal in the early dilation of resistance vessels, whereas dilation of conductance vessels may be a secondary phenomenon triggere

Exercise is the most important physiological stimulus for increased myocardial oxygen demand. The requirement of exercising muscle for increased blood flow necessitates an increase in cardiac output that results in increases in the three main determinants of myocardial oxygen demand: heart rate, myocardial contractility, and ventricular work. The approximately sixfold increase in oxygen demands of the left ventricle during heavy exercise is met principally by augmenting coronary blood flow (∼5-fold), as hemoglobin concentration and oxygen extraction (which is already 70–80% at rest) increase o

Streszczenie:

Cardiac tumors are rarely encountered in clinical practice; however, because they affect vital structures, they can have significant consequences. Cardiac tumors are categorized as either primary tumors originating from cardiac tissue or metastatic tumors migrated from other sites; they may infiltrate the atria, ventricles, valves, and coronary arteries, resulting in considerable changes to normal physiology. They may extend beyond the myocardium to the pericardium, great vessels, and mediastinum. Advances in the development of imaging modalities have allowed for expedited diagnostic evaluation of cardiac tumors. Prompt treatment, which often includes surgical intervention, is essential to both alleviate symptoms and prevent harmful sequelae. The intraoperative anesthetic management of a patient with a cardiac mass presents a number of challenges due to altered cardiovascular physiology. Because these tumors occur so infrequently, standardized, evidence-based diagnostic and treatment guidelines have not been developed. The existing data were derived mainly from small case series and case reports. The aggressive nature of the disease warrants further investigation to improve the accuracy of diagnostic modalities and the efficacy of treatment regimens.

Streszczenie:

For over a century astute clinicians have recognized that prodromal symptoms often precede acute myocardial infarction (MI). The evolution of symptoms was subsequently found to correlate with changes in atherosclerotic plaque composition, morphology, and thrombogenicity, leading to the classification of symptoms that are currently categorized to better delineate diagnostic and management strategies. Acute coronary syndromes (ACSs) are traditionally divided into two separate categories—ST-segment elevation and non–ST-segment elevation ACS—based on the presenting electrocardiogram. The latter category is then subdivided into unstable angina and non–ST-segment elevation MI, based on the absence or presence of elevated cardiac biomarkers, respectively. This chapter considers ST-segment elevation MI and non–ST-segment elevation ACS based on pharmacologic and clinical (diagnostics and routine management) constructs. ST-segment elevation MI (STEMI), in a vast majority of cases, is caused by occlusive thrombosis at a site of plaque rupture. In others, particularly when the stimulus for thrombosis is strong, occlusion may follow minor disruption of the plaque surface (erosion) or occur in areas of endothelial cell injury (activation with inflammatory features and concomitantly impaired vascular thromboresistance). Coronary arterial spasm, in the absence of intrinsic vascular disease (as may be seen with cocaine use), can also impair restrictive blood flow to the myocardium, resulting in cellular death. The goal of pharmacology-based therapy (and mechanical intervention) is to restore myocardial blood flow as quickly and completely as possible. The “open vessel hypotheses” predicts that rapid, complete, and sustained myocardial perfusion through the prompt restoration of physiologic blood flow will minimize (salvage) myocardium, promote ventricular performance, and reduce mortality. Strong support for the open-vessel hypothesis can be traced to the Thrombolysis and Myocardial Infarction (TIMI) trial performed in the 1980s (Dalen et al., 1988; TIMI Study Group, 1985). Patients with patent infarct-related coronary arteries 90 minutes after the initiation of fibrinolytic therapy had an 8.1% mortality at 1 year, compared to a 14.8% mortality among those with an occluded vessel. Since that time, several large-scale clinical trials have confirmed the importance of an open infarct-related coronary artery for early, intermediate, and long-term outcome.

The failure of fibrinolytic therapy to restore physiologic myocardial perfusion in upward of 40% of patients supports the development of strategies to improve response rates to percutaneous coronary intervention (PCI) in those requiring early procedures. The construct of facilitated PCI (pharmacoinvasive therapy) provides a platform for utilizing the strengths of existing therapies and treatment modalities. The Heparin in Early Patency (HEAP) trial (Zijlstra et al., 2002) included 1,702 patients treated with primary PCI for myocardial infarction (MI); 860 patients received aspirin (500 mg IV) and UFH (≥5,000 U IV) before being transported to the hospital and 842 patients received the same antithrombotic therapy in the hospital. TIMI 2 or 3 flow rates were higher in the pretreated group (31% vs. 20%; p = .001), and patients with TIMI 2 or 3 flow initially had a higher PCI success rate (94% vs. 89%; p <.001) and a lower 30-day mortality (1.6% vs. 3.4%; p = .04). The Plasminogen Activator Angioplasty Compatibility Trial (PACT) randomized 606 patients to receive a 50-mg bolus of alteplase or placebo, followed by immediate angiography and angioplasty if needed (Ross et al., 1999). TIMI flow rates on arrival to the catheterization laboratory were 33% and 15%, respectively. Facilitated PCI and primary PCI restored TIMI 3 flow in occluded vessels equally (77% and 79%, respectively). There were no differences in major bleeding. Left ventricular ejection fraction was highest in those with TIMI 3 flow on arrival to the catheterization laboratory or following PCI within 1 hour of alteplase administration. Full-dose fibrinolytic therapy with alteplase or reteplase followed by coronary angiography and PCI (if no clinical evidence of reperfusion) was evaluated retrospectively in the Global Use of Strategies to Open Occluded Arteries (GUSTO) III trial (Miller et al., 1999). Among those undergoing PCI (n = 392), 87 patients received in-laboratory abciximab. A trend toward reduced mortality was observed in abciximab-treated patients, but at a higher cost of hemorrhagic complications. In the Strategies for Patency Enhancement in the Emergency Department (SPEED) trial (Herrmann et al., 2000), 323 patients who underwent PCI had an 88% procedural success rate and a 30-day composite of death, reinfarction, or revascularization of 5.6%.
