Previous studies conducted to investigate the relationship between sodium intake and blood pressure in our African population have yielded contradictory results. With the high prevalence of obesity in this population, it is possible that these contradictory findings are due to the masking effects of obesity on this relationship. We measured 24-hour ambulatory blood pressure and 24-hour urine excretion on 547 South Africans of African ancestry. A multivariate regression analysis revealed no independent relationship between 24-hour sodium excretion and blood pressure in the total population sample, but when participants were stratified according to body mass index (BMI) status, there was a significant association between 24-hour sodium excretion and blood pressure in the normal-BMI participants but not in the overweight/obese participants...

We report on the case of a 27-year-old male who presented to our emergency room with chest tightness, dyspnoea and cold sweats. The 12-lead electrocardiogram showed diffuse ventricular tachycardia with wide QRS complexes. Troponin-I level was elevated to 100 ng/ml. The coronary angiogram showed good patency of all three coronary vessels, and acute fulminant myocarditis was suspected. The patient underwent cardiopulmonary resuscitation in the catheter room and high-dose inotropic support was initiated to stabilise his haemodynamic status...

BACKGROUND: In chronic rheumatic mitral regurgitation (CRMR), involvement of the myocardium in the rheumatic process has been controversial. Therefore, we sought to study the presence of fibrosis using late gadolinium enhancement cardiac magnetic resonance imaging (LGE-CMR) and biomarkers of collagen turnover in CRMR. METHODS: Twenty-two patients with CRMR underwent CMR and echocardiography. Serum concentrations of matrix metalloproteinase- 1 (MMP-1), tissue inhibitor of MMP-1 (TIMP- 1), MMP-1-to-TIMP-1 ratio, procollagen III N-terminal pro-peptide (PIIINP) and procollagen type IC peptide (PIP) were measured...

BACKGROUND: Most intra-coronary stents in use are made of 316 L stainless steel, which contains nickel, chromate and molybdenum. Whether inflammatory and allergic reactions to metals contribute to in-stent restenosis is still a matter of debate. AIM: The aim of this study was to ascertain the relationship between metal allergy and the occurrence of in-stent restenosis. METHODS: Ninety-nine adult patients who underwent two cardiac catheterisations, up to two years apart, were included in the study...

BACKGROUND: In this study, we describe the technique of eversion of the native aortic tissue to prevent suture line complications, and report on our results with this technique. METHODS: A total of 42 patients who were operated on due to aortic aneurysm were retrospectively assessed. In all patients, an aortic segment of approximately 2 cm, which was left both distally and proximally, was everted to form a double-layer lumen and the grafts were anastomosed. Postoperative outcomes and long-term follow-up results were assessed...

METHODS: A total of 2 354 individuals were assessed for behavioural, sociodemographic and physical characteristics in a cross-sectional, community-based survey. Post-stratification survey weights were applied to obtain prevalence levels...

Psoriasis (PsO) is a chronic immune-mediated inflammatory skin disorder associated with numerous co-morbidities. This descriptive review focuses on the cardiometabolic co-morbidities of PsO with reference to the epidemiology and pathogenetic mechanisms linking PsO and cardiometabolic disease (CMD). Registry-based studies have shown PsO to be associated with an increased risk of cardiovascular morbidity and mortality. Factors linking PsO and CMD include: chronic inflammation, obesity, classic cardiovascular risk factors, and the effects of systemic therapy used to treat PsO...

OBJECTIVES: Few studies have evaluated young adults in their third and fourth decades with coronary artery disease (CAD). This study evaluated the clinical and angiographic profile of young adults ( < 35 years) with CAD. METHODS: A 10-year (2003-2012) retrospective chart review was performed on patients less than 35 years diagnosed with CAD at Inkosi Albert Luthuli Central Hospital, Durban. RESULTS: Of the 100 patients who met the study criteria, the majority were male (90%), of Indian ethnicity (79%), and presented with acute coronary syndrome (93%)...

REVIEW
Julien I Hoffman
Critical coarctation of the aorta in neonates is a common cause of shock and death. It may be the most difficult of all forms of critical congenital heart disease to diagnose because the obstruction from the coarctation does not appear until several days after birth (and after discharge from the hospital), and because there are no characteristic murmurs. Some of these patients may be detected by neonatal screening by pulse oximetry, but only a minority is so diagnosed. Older patients are usually asymptomatic but, although clinical diagnosis is easy, they are frequently undiagnosed...

INTRODUCTION: Fatty liver disease (FLD) is correlated with cardiovascular disease. Carotid intima-media thickness (CIMT) and coronary artery calcium score (CACS) can noninvasively identify subclinical atherosclerosis and predict risk for cardiovascular events. This study evaluated CIMT and CACS measurements to detect subclinical atherosclerosis in patients with and without FLD. METHODS: Patients who underwent carotid and abdominal ultrasounds as well as cardiac computed tomography (CT) scans were evaluated retrospectively...

OBJECTIVE: The aims of this study were to report on our experience with upper limb ischaemia (ULI), to define the pattern and distribution of disease, describe key demographic features and report on conventional clinical outcomes. METHODS: This was a single-centre, retrospective, descriptive study. All patients (n = 64) who underwent a surgical intervention for ULI over a 12-year study period were included. Findings were analysed and compared with the current literature...

INTRODUCTION: Changes in left atrial (LA) size and function are associated with adverse clinical events. Recently, duration of diabetes mellitus (DM2) has been found to be positively associated with increased LA volume and impaired LA function. This study was performed, using two-dimensional echocardiograpy, to evaluate the changes in LA volume and function in patients with DM2 with a disease duration of six months, and to assess the parameters that affect LA volume and function. METHODS: Fifty-six patients (28 male, age: 52...

Miller-Fisher syndrome (MFS) is an uncommon neurological disorder that is considered a variant of the Guillain-Barre syndrome (GBS). It is clinically defined by a triad of symptoms, namely ataxia, areflexia and ophthalmoplegia. These acute inflammatory polyradiculopathic syndromes can be triggered by viral infections, major surgery, pregnancy or vaccination. While the overall incidence of GBS is 1.2-2.3 per 100 000 per year, MFS is a relatively rare disorder. Only six cases of GBS after cardiac surgery have been reported, and to our knowledge, we describe the first case of MFS after coronary artery bypass surgery...

Acute aortic dissection is the most frequent and deadly presentation of acute aortic syndromes. Its incidence is estimated at three to four cases per 100 000 persons per year. Its clinical presentation may be misleading, with misdiagnosis ranging between 14.1 and 38% in many series. A late diagnosis or absence of early and appropriate management is associated with mortality rates as high as 50 and 80% by the third day and second week, respectively, especially in proximal lesions. We report on the case of a 53-year-old man who presented with type A aortic dissection, misdiagnosed as acute myocardial infarction, who later died on day 12 of hospitalisation...

BACKGROUND: The objectives of this study were to assess the prevalence of obesity in Dakar and in Tessekere, a rural municipality in northern Senegal, and to compare ideal body size between these populations. METHODS: A cross-sectional survey was carried out in 2015 on a representative sample of 1 000 adults, aged 20 years and older in Dakar, and 500 adults of the same age in Tessekere. RESULTS: The prevalence of obesity and overweight was higher in Dakar than in Tessekere...

BACKGROUND: Pulmonary hypertension (PH) is prevalent in Africa and is still often diagnosed only at an advanced stage, therefore it is associated with poor quality of life and survival rates. In resource-limited settings, we assessed the diagnostic utility of standard 12-lead electrocardiograms (ECG) to detect abnormalities indicating PH. METHODS: Sixty-five patients diagnosed with PH were compared with 285 heart disease-free subjects. The prevalence and diagnostic performance of ECG features indicative of PH and right heart strain were calculated...
