1/45. Decreased left ventricular filling pressure 8 months after corrective surgery in a 55-year-old man with tetralogy of fallot: adaptation for increased preload.A 55-year-old man with tetralogy of fallot underwent corrective surgery. Left ventricular filling pressure increased markedly with increased left ventricular volume one month after surgery, then decreased over the next 7 months, presumably due to increased left ventricular compliance.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/45. The combination of risk factors for sudden death in a resuscitated elderly patient with an exceptional cause of left ventricular hypertrophy.The work-up of a previously asymptomatic 72-year-old man presenting with sudden cardiac death revealed a coarctation of the aorta as the cause of arterial hypertension, severe left ventricular hypertrophy, in combination with coronary artery disease with an apical myocardial infarction, severe autonomic dysfunction, and AV-nodal reentrant tachycardia. All these elements and their complex, probably synergistic interactions might have been involved in the development of sudden cardiac death.- - - - - - - - - - ranking = 1.9462372158256keywords = hypertension (Clic here for more details about this article) |
3/45. Coronary artery aneurysms, aortic dissection, and hypertension secondary to primary aldosteronism: a rare triad. A case report.Primary aldosteronism is a relatively uncommon etiology of hypertension. plasma renin activity is suppressed in the majority of the cases but not always. plasma renin activity has been associated with increased vascular injury. The occurrence of vascular complications has rarely been reported with low plasma renin activity. The authors report a case of long-standing secondary hypertension due to primary aldosteronism with coronary artery aneurysms and aortic dissection. Diagnosing is important, for therapeutic intervention can be curative.- - - - - - - - - - ranking = 11.677423294954keywords = hypertension (Clic here for more details about this article) |
4/45. A probable relationship between an endogenous digitalis-like substance and concentric cardiac hypertrophy in primary aldosteronism.A 44-year-old woman was admitted to our hospital due to severe hypertension. An electrocardiogram (ECG) and an echocardiogram showed severe left ventricular hypertrophy. Her plasma aldosterone level was elevated. magnetic resonance imaging revealed a small mass in the right adrenal gland. Before removal of the tumor, plasma endogenous digitalis-like substance (EDLS) levels were elevated. After removal of the tumor, EDLS levels quickly returned to the normal level. A series of echocardiograms and ECGs over a 6- year period after removal of the tumor showed marked regression of cardiac hypertrophy. These findings suggest that EDLS may be closely related to the development of concentric cardiac hypertrophy in primary aldosteronism.- - - - - - - - - - ranking = 1.9462372158256keywords = hypertension (Clic here for more details about this article) |
5/45. Case 3: A patient with systemic hypertension and left ventricular hypertrophy.hypertension is often referred to as the "silent killer" because most hypertensive patients are asymptomatic until cardiovascular sequelae such as stroke, myocardial infarction, heart failure, or renal failure occur. LVH is a common finding in patients with hypertension, especially African-Americans. Data from the Framingham Heart Study indicate that LVH is an independent risk factor for major cardiovascular events. In the amlodipine Cardiovascular Community Trial, 37% of 124 hypertensive patients screened by means of echocardiography had LVH at baseline. Although there was no difference in the prevalence of LVH by gender or age, African-American patients were nearly twice as likely to have LVH than white patients (64% vs. 34%, p<0.05). Hence, aggressive therapy to reach target goals outlined in the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High blood pressure (JNC VI) is especially important in this group of patients. Even lifestyle modifications such as weight reduction and limitation of salt intake, if sufficiently aggressive, can lead to regression of LVH, as demonstrated by results of the Treatment of Mild hypertension Study (TOMHS). Most classes of antihypertensive drugs are effective in causing regression of LVH. Vasodilators, such as minoxidil and hydralazine, do not have an effect on regression, possibly because reflex tachycardia and stimulation of catecholamines and the renin-angiotensin system associated with these agents may negate the benefit of reduced afterload. There is some controversy regarding the ability of the angiotensin receptor blockers to reduce LVH. In some studies, these agents were associated with regression, whereas in others they were not. Whether targeting LVH as the primary treatment goal in hypertensive patients will have long-term benefits on outcome above and beyond simply reducing blood pressure is not clear.- - - - - - - - - - ranking = 13.232288940825keywords = blood pressure, hypertension, pressure (Clic here for more details about this article) |
6/45. Transient right sided hypertrophic cardiomyopathy in an infant born to a diabetic mother.Hypertrophic cardiomyopathy (HCM) is a rare primary myocardial disease, characterized by hypertrophy of the left and/or right ventricle. Infants of diabetic mothers (IDM) are at risk for development of HCM, respiratory distress and persistent pulmonary hypertension. A case of severe right sided HCM in an infant born to a diabetic mother is presented. The patient's findings were complementary to the previous observations reporting HCM in IDM. The presence of disproportionate septal hypertrophy in the echocardiography of an infant born to a diabetic mother is highly suggestive of HCM in IDM. In our opinion, further cardiac evaluation is not indicated unless other cardiac abnormalities are suspected.- - - - - - - - - - ranking = 1.9462372158256keywords = hypertension (Clic here for more details about this article) |
7/45. A depressed myocardium.BACKGROUND: Venlafaxine is a potent neuronal serotonin and noradrenaline re-uptake inhibitor, and to a lesser extent an inhibitor of dopamine reuptake. paroxetine is a potent selective inhibitor of serotonin reuptake. CASE REPORT: A 27-year-old man ingested 1987.5 mg of venlafaxine and 360 mg of paroxetine. He subsequently developed systolic and diastolic hypertension, transient electrocardiographic abnormalities, and an area of persistent myocardial damage. He recovered from his overdose with his blood pressure and electrocardiogram returning to normal. The area of myocardial damage was documented on echocardiogram as an area of marked hypokinesia at the basal anterior septum. Despite the absence of confirming blood levels or the absolute exclusion of cocaine, this case indicates that venlafaxine and paroxetine have the potential for serious cardiotoxicity when taken in overdose.- - - - - - - - - - ranking = 5.4473400775225keywords = blood pressure, hypertension, pressure (Clic here for more details about this article) |
8/45. association of pulmonary atresia with intact ventricular septum and aortic valve stenosis. prenatal diagnosis.A rare association of pulmonary atresia with an intact septum was diagnosed through echocardiography in a fetus 32 weeks of gestational age. The diagnosis was later confirmed by echocardiography of the newborn infant and further on autopsy. The aortic valve was bicuspid with a pressure gradient of 81 mmHg, and the right ventricle was hypoplastic, as were the pulmonary trunk and arteries, and the blood flow was totally dependent on the ductus arteriosus.- - - - - - - - - - ranking = 0.2keywords = pressure (Clic here for more details about this article) |
9/45. Antihypertensive therapy reduces increased plasma levels of adrenomedullin and brain natriuretic peptide concomitant with regression of left ventricular hypertrophy in a patient with malignant hypertension.We investigated the potential role of increased plasma adrenomedullin and brain natriuretic peptide (BNP) levels in a patient with malignant hypertension. A 51-year-old man was admitted to our hospital with a chief complaint of visual disturbance. His blood pressure was 270/160 mmHg on admission. Papillary edema associated with retinal bleeding was observed. echocardiography revealed marked concentric left ventricular hypertrophy with mild systolic dysfunction. plasma levels of adrenomedullin and BNP were markedly elevated. Antihypertensive therapy reduced the plasma levels of adrenomedullin in association with a concomitant decrease in blood pressure. The plasma level of BNP also decreased and regression of left ventricular hypertrophy and normalization of left ventricular systolic function were observed. Our findings suggest that adrenomedullin may be involved in the defense mechanism against further elevations in blood pressure in patients with hypertension and that the plasma level of BNP may reflect left ventricular systolic dysfunction, left ventricular hypertrophy, or both, in patients with severe hypertension.- - - - - - - - - - ranking = 24.12696909587keywords = blood pressure, hypertension, pressure (Clic here for more details about this article) |
10/45. Apical aneurysm and left ventricular hypertrophy.A 59-year-old woman presented with an embolic transient ischemic attack and a history of controlled hypertension for 16 years. Both echocardiogram and MRI showed severe biventricular hypertrophy and an apical aneurysm with a thrombus. The occurrence of an apical aneurysm in the presence of cardiac hypertrophy is a rare finding and has been described in patients with hypertrophic cardiomyopathy. However, it has not been reported in patients with systemic arterial hypertension. In this patient the lack of a relationship between the severity of the hypertrophy and the levels of blood pressure, together with the presence of histologic disorganization of myocardial cardiac muscle cells by endomyocardial biopsy suggested the diagnosis of hypertrophic cardiomyopathy.- - - - - - - - - - ranking = 7.3935772933481keywords = blood pressure, hypertension, pressure (Clic here for more details about this article) |
