Left ventricular hypertrophy and other cardiac risk factors in migraineurs

Cardiovascular diseases are the major cause of mortality in uraemic patients treated by hemodialysis. Left ventricular hypertrophy (LVH) is considered to be a major cardiac risk factor.AIM: To investigate the presence of some potential adverse risk factors in hemodialysis patients with developed LVH echocardiography verified and determine their relative contribution to the LVH in comparison with patients with normal LV.METHOD: The study included 50 patients with end-stage renal disease in the first 2 years of hemodialysis treatment, who were followed up during one year. All participants have the echocardiography performed as well as serial measurements of potential modifiable cardiovascular risk factors.RESULTS: This investigation showed that LVH is present in high percentage (72%) in uraemic patients, even at the beginning of hemodialysis treatment. This LV morphological abnormality is statistically significantly related to anaemia (p<0,001), systolic (p<0,001) and diastolic hypertension (p<0,001)), elevated mean arterial pressure (p<0,001) and hyperparathyroidism (p=0,002).CONCLUSION: Modification of existing risk factors in uraemic patients could contribute to prevention and treatment of LV hypertophy and thus reduce cardiovascular morbidity and mortality.

Abstract The fourth, fifth, and sixth editions of the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) use left ventricular hypertrophy (LVH) as a variable to determine impairment caused by hypertensive disease. The issue of LVH, as assessed echocardiographically, is a prime example of medical science being at odds with legal jurisprudence. Some legislatures have allowed any cause of LVH in a hypertensive individual to be an allowed manifestation of hypertensive changes. This situation has arisen because a physician can never say that no component of LVH was not caused by the hypertension, even in an individual with a cardiomyopathy or valvular disorder. This article recommends that evaluators consider three points: if the cause of the LVH is hypertension, is the examinee at maximum medical improvement; is the LVH caused by hypertension or another factor; and, if apportionment is allowed, then a careful analysis of the risk factors for other disorders associated with LVH is necessary. The left ventricular mass index should be present in the echocardiogram report and can guide the interpretation of the alleged LVH; if not present, it should be requested because it facilitates a more accurate analysis. Further, if the cause of the LVH is more likely independent of the hypertension, then careful reasoning and an explanation should be included in the impairment report. If hypertension is only a partial cause, a reasoned analysis and clear explanation of the apportionment are required.

Objective Obesity has been linked to a spectrum of cardiovascular abnormalities from subclinical changes in cardiac structure to overt heart failure. Uncomplicated obesity (i.e. obesity without any other co-morbidity or cardiovascular risk factors) has been shown to cause increased LV mass and LV dilatation. Our hypothesis was that these changes are, at least in part, reversible following significant weight loss over one year. Method Forty-one obese (BMI 37.7 ± 7.4 SD) and 12 age, sex matched controls (BMI 21.6 ± 1.8 SD) with no identifiable cardiac risk factors underwent cardiac MR imaging for the assessment of LV Mass (g), LV end-diastolic volume (EDV; ml), stroke volume (SV; ml) and LV EF (%). Fourteen obese subjects underwent repeat imaging after a one year period of weight loss, averaging 14.6 ± 11.5 % total body weight. Results Obesity per se was associated with elevated LV mass (125 ± 27 vs 89 ± 23g; p<0.001), LV mass indexed to height (74.4 ± 14.3 vs 52.3 ± 11.4g/m; p<0.001) and EDV (147 ± 28 vs 119 ± 24 ml; p<0.001). ESV and SV were also elevated in obesity (47 ± 12 vs 39 ± 12ml; p=0.05, and 100 ± 14 vs 80 ± 18 ml; p<0.001, respectively). LV EF was similar between groups (p=0.83). After weight loss, there was a significant reduction in LV mass (by 16 ± 11g; 135 ± 31 vs 119 ± 28g; p<0.001), LV mass indexed to height (76.4 ± 15.7 vs 68.9 ± 12 g/m; p<0.001). EDV and ESV were significantly smaller after weight loss (146 ± 25 vs 133 ± 23 ml; p<0.001, and 43 ± 12 vs 41 ± 10 ml; p<0.001 respectively). LV EF and SV did not change significantly. Conclusion In subjects with obesity in the absence of identifiable cardiac risk factors, LV hypertrophy and LV dilatation were partially reversible after a one year period of weight loss.

Cardiovascular Morbidity And Mortality

Left ventricular hypertrophy is the main risk factor for development of cardiovascular morbidity and mortality in patients on hemodialysis. Left ventricular hypertrophy is found in 75% of the patients treated with hemodialysis. Risk factors for left ventricular hypertrophy in patients on hemodialysis include: blood flow through arterial-venous fistula, anemia, hypertension, increased extracellular fluid volume, oxidative stress, microinflammation, hyperhomocysteinemia, secondary hyperpara- thyroidism, and disturbed calcium and phosphate homeostasis. Left ventricular pressure overload leads to parallel placement of new sarcomeres and development of concentric hypertrophy of left ventricle. Left ventricular hypertrophy advances in two stages. In the stage of adaptation, left ventricular hypertrophy occurs as a response to increased tension stress of the left ventricular wall and its action is protective. When volume and pressure overload the left ventricle chronically and without control, adaptive hypertrophy becomes maladaptive hypertrophy of the left ventricle, where myocytes are lost, systolic function is deranged and heart insufficiency is developed. Left ventricular mass index-LVMi greater than 131 g/m2 in men and greater than 100 g/m2 in women, and relative wall thickness of the left ventricle above 0.45 indicate concentric hypertrophy of the left ventricle. Eccentric hypertrophy of the left ventricle is defined echocardiographically as LVMi above 131 g/m2 in men and greater than 100 g/m2 in women, with RWT ?0.45. Identification of patients with increased risk for development of left ventricular hypertrophy and application of appropriate therapy to attain target values of risk factors lead to regression of left ventricular hypertrophy, reduced cardiovascular morbidity and mortality rates and improved quality of life in patients treated with regular hemodialyses.

ObjectivesLifestyle and working conditions of truck drivers predisposes them to risk-factors associated with communicable and non-communicable diseases, but little is known about the health status of African truck driver. This study aims to assess a cross-section of truckers in South Africa to describe their health information.SettingThe study took place across three truck-stop rest areas in the South African provinces of Free State and Gauteng.ParticipantsEligibility criteria included being males aged 18 years and older, full-time employment as a long-distance truck driver. A total of 614 male truck drivers participated; 384 (63%) were Zimbabwean and 325 (55%) completed high-school.Primary and secondary outcome measuresThe trucker survey explored demographics; working conditions; sexual, eating and sleeping behaviours; mental health status, medical history and cardiac risk-factors. Medical assessments included physical measurements, glucose and lipid measurements, ECG, carotid intima-media thickness (CIMT) and cardiac ultrasound.ResultsIn the previous month, 554 (91%) participants were sexually active; 522 (86%) had sex with a regular partner; 174 (27%) with a casual partner; 87 (14%) with a sex worker. Average time driving was 10 hours/day, 20 days/month, 302 (50%) never worked night shifts and 74 (12%) worked nights approximately four times per week. 112 (18%) experienced daytime sleepiness and 59 (10%) were ever hospitalised from an accident. Forty-seven (8%, 95% CI 5.3 to 9.5) were HIV-positive, with half taking antiretrovirals. Forty-eight (8%) truckers had some moderate depression, while 21 (4%) suffered from post-traumatic stress disorder. Reported tuberculosis, myocardial infarction, and diabetes were <3%. Prominent cardiac risk-factors included smoking (n=63, 11%), consuming alcohol (>15 drinks/week) (n=54, 9%), overweight/obesity (n=417, 69%), and hypertension (n=220, 36%,95% CI 32.1 to 39.7). ECG results showed 23 (4.9%) and 29 (5.3%) drivers had left ventricular hypertrophy using the Cornell criterion and product, respectively. CIMT measurements indicated nine (4.2%) drivers had a carotid atherosclerotic plaque.ConclusionThis first holistic assessment of health among southern African male truck drivers demonstrates substantial addressable cardiovascular risk factors, mental health issues and sexual risk behaviours.
