Non Invasive

Many non-invasive imaging techniques are available for the evaluation of patients with known or suspected coronary heart disease. Among these, computed-tomography-based techniques allow the quantification of coronary atherosclerotic calcium and non-invasive imaging of coronary arteries, whereas nuclear cardiology is the most widely used non-invasive approach for the assessment of myocardial perfusion. The available single-photon-emission computed tomography flow agents are characterised by a cardiac uptake proportional to myocardial blood flow. In addition, different positron emission tomography tracers may be used for the quantitative measurement of myocardial blood flow and coronary flow reserve. Extensive research is being performed in the development of non-invasive coronary angiography and myocardial perfusion imaging using cardiac magnetic resonance. Finally, new multimodality imaging systems have recently been developed bringing together anatomical and functional information. This article provides a description of the available non-invasive imaging techniques in the assessment of coronary anatomy and myocardial perfusion in patients with known or suspected coronary heart disease.

According to the literature data, gallbladder (GB) condition influences the course of coronary heart disease (CHD) and parameters of heart structure and function. The aim of this work was to estimate the peculiarities of heart condition in patients with CHD (acute myocardial infarction) in dependence of GB condition. We held a retrospective analysis of data of 142 patients. Results. It was revealed that in 83.7 % patients GB was changed: cholelithiasis (34.5 %), past cholecystectomy due to cholelithiasis (7.0 %), sludge and poliposis (17.6 %), bent GB body (13.4 %), neck deformations and signs of past cholecystitis (14.8 %). GB changes were accompanied by significant increase of heart rate, which was the most prominent in case of cholelithiasis, neck deformations and past cholecystitis signs. Conclusions. Pathological conditions of GB were accompanied by left ventricle dilatation, aortic distension, significant decrease of ejection fraction and systolic dysfunction, whereas after GB removal sizes of heart chambers were close to optimal values, although the systolic function did not normalize.

Abstract Background Rheumatic heart disease remains a considerable cause of cardiovascular morbidity and mortality in developing countries and mitral stenosis is the most common valve affection of rheumatic heart disease worldwide.The left ventricular ejection fraction is the most widely used index of contractile function, but due to the visual component, assessment of endocardial excursion is subjective leading to inter-observer variability.Speckle-tracking echocardiography is an imaging technique developed as a method to objectively quantify myocardial function and analyzes cardiac motion and deformation by tracking naturally occurring speckle patterns in the myocardium. Objective To evaluate the effect of the severity of mitral stenosis on LV systolic function as assessed by speckle tracking. Patients and Methods This study was a case-control study involving 80 individuals which included 60 patients having mitral stenosis who presented to the outpatient clinics of Ain Shams University Hospitals and 20 healthy volunteers, The patients suffering from mitral stenosis were subdivided into 3 sub-groups: GROUP(1) 20 Patients having severe mitral stenosis (MV Area less than 1 cm²) GROUP (2) 20 Patients having moderate mitral stenosis (MV Area more than 1 cm² and less than 1.5 cm²) GROUP(3) 20 Patients having mild mitral stenosis (MV Area more than 1.5 cm²) A Control group involved 20 healthy volunteers recruited from health care workers in Ain Shams University hospitals. Results Study included 60 patients,16 males (26.7%) and 44 females (73.3%), with mean age of 41.30 ± 8.64 years. Patients living in rural Areas were 34 (57.7%) while those in urban areas were 26 (43.3%).Which was significant.There was no significant difference between gender or habitat and the severity of mitral Stenosis.There was a strong significance between the duration of the disease and its severity. The more the duration of mitral Stenosis, the more severe the mitral stenosis.A strong positive relation was noticed between the severity of mitral stenosis and both RVSP and LA diameter, while a strong negative relation between severity of mitral stenosis and GLPS. GLPS was affected in severe mitral stenosis only. Conclusion Subtle LV systolic dysfunction is present in large number of patients with severe mitral stenosis even in patients with normal ejection fraction by conventional 2D echocardiography.There was a significant relationship between the duration of mitral stenosis and its severity. The longer the duration of mitral stenosis, the more severe the mitral stenosis.Speckle tracking echocardiography (STE) can play a great role in identification of higher risk subgroups in whom earlier and more aggressive intervention could have a significant impact on their prognosis.

Invasive Evaluation

The left ventricular (LV) ejection fraction (EF) is the preferred parameter applied for the non-invasive evaluation of LV systolic function in clinical practice. It has a well-recognized and extensive role in the clinical management of numerous cardiac conditions. Many imaging modalities are currently available for the non-invasive assessment of LVEF. The aim of this review is to describe their relative advantages and disadvantages, proposing a hierarchical application of the different imaging tests available for LVEF evaluation based on the level of accuracy/reproducibility clinically required.

The diagnosis of stable ischemic heart disease begins with a careful clinical examination of the patient and non-invasive testing to identify the disease. Patients with very low and very high pretest probability should not undergo various non-invasive tests. Various non-invasive tests are available to assess the presence of coronary heart disease in patients with an intermediate probability of ischemic heart disease (15–65%). The combination of anatomical with functional non-invasive tests helps improve diagnostic capabili of the disease.

ObjectiveNon-invasive assessment of left ventricular (LV) diastolic and systolic function is important to better understand physiological abnormalities in heart failure (HF). The spatiotemporal pattern of LV blood flow velocities during systole and diastole can be used to estimate intraventricular pressure differences (IVPDs). We aimed to demonstrate the feasibility of an MRI-based method to calculate systolic and diastolic IVPDs in subjects without heart failure (No-HF), and with HF with reduced ejection fraction (HFrEF) and HF with preserved ejection fraction (HFpEF).MethodsWe studied 159 subjects without HF, 47 subjects with HFrEF and 32 subjects with HFpEF. Diastolic and systolic intraventricular flow was measured using two-dimensional in-plane phase-contrast MRI. The Euler equation was solved to compute IVPDs in diastole (mitral base to apex) and systole (apex to LV outflow tract).ResultsSubjects with HFpEF demonstrated a higher magnitude of the early diastolic reversal of IVPDs (−1.30 mm Hg) compared with the No-HF group (−0.78 mm Hg) and the HFrEF group (−0.75 mm Hg; analysis of variance p=0.01). These differences persisted after adjustment for clinical variables, Doppler-echocardiographic parameters of diastolic filling and measures of LV structure (No-HF=−0.72; HFrEF=−0.87; HFpEF=−1.52 mm Hg; p=0.006). No significant differences in systolic IVPDs were found in adjusted models. IVPD parameters demonstrated only weak correlations with standard Doppler-echocardiographic parameters.ConclusionsOur findings suggest distinct patterns of systolic and diastolic IVPDs in HFpEF and HFrEF, implying differences in the nature of diastolic dysfunction between the HF subtypes.

Background: With the evaluation of focal epicardial coronary stenosis and non-obstructive atherosclerosis, the cardiac scans play a significant role in diagnosing coronary artery disease (CAD). Moreover, the advancements in the imaging techniques leading to improved risk assessment and timely therapies help in early diagnosis of CAD with greater accuracy. Aims: To evaluate the role of cardiac scan in diagnosing CAD. Methods: Recruited 100 individuals without any history of CAD that refers to the assessment of suspected angina, conducted the prospective study. Electrocardiogram (ECG) findings assisted in the evaluation of left bundle branch blockage, abnormalities of ST-segment, and pathological Q waves. Results: The results depicted negative N.M findings among 38 respondents; whereas, ischemia and myocardial infarctions were diagnosed in 26% and 19% of the respondents, respectively. The majority of the males (59) were positive in contrast to 37 females with positive results. Similarly, 24 respondents were presented with mild dilated left atria (LA), 37 respondents suffered from impaired relaxation pattern of left ventricular (LV) diastolic filling; while, 40 of the respondents had normal global LV systolic function. Conclusion: The study results have concluded that non-invasive, low-risk, and cost-effective technique like ECG is an important beneficial advancement in the diagnosis of CAD.
