Acute myocardial infarction following "dry scooping" of a pre-workout supplement in a healthy young man of African origin: A case report.

Dry scooping, a rather risky act of consuming undiluted pre-workout protein powder hoping for a more pronounced energy surge, is increasingly becoming a fitness trend worldwide. A previously healthy 25-year-old man of African origin presented with acute onset of crushing mid-sternal chest pain for 4 h. His symptoms began about an hour following completion of his 2-h exercise regimen at the gym. He had an unremarkable past medical history except for an 8-month consumption of a pre-workout supplement as part of his gym routine. He claimed to have adhered to the manufacturer's recommended method of using the supplement, except for 3 days prior to presentation when he started "dry scooping" following the viewing of a video advocating such practice from his fitness WhatsApp group. Cardiac evaluation revealed features in keeping with diagnosis of anterolateral ST-elevation myocardial infarction. Emergency coronary angiography revealed a thrombotic lesion completely occluding the proximal left anterior descending coronary artery with TIMI 0 flow distally. After successful balloon angioplasty, a drug-eluting stent was implanted successfully, restoring TIMI 3 flow to the proximal left anterior descending coronary artery. This case report aims to raise awareness among both clinicians and the general public regarding the pervasiveness of pre-workout supplements, improper methods of consumption, and the potential life-threatening repercussions of misuse.

Perspectives for the Prevention of Noncommunicable Diseases in Tanzania: Is Knowledge Translated into Practice?

Background: In Tanzania, where over a third of the society is impoverished, the burden of NCDs which account for about two-fifths of all disability-adjusted life years (DALYs) and one-third of premature deaths has doubled in the past two decades. However, notwithstanding a wider realization of the escalating burden of NCDs across Tanzania, the link between NCD awareness and lifestyle practices at the population level is not well characterized. We aimed to establish the gap between NCD knowledge and healthy behaviors. Methods: This multi-regional community-based cross-sectional study was conducted in 5 regions of Tanzania between September 2022 and June 2023. A 22-item standardized tool evaluating various NCD risk behaviors was used in knowledge assessment and a cut-off of ≥70% was used to denote good knowledge. Bivariate analyses were performed to compare knowledge of NCD risk factors across various NCD risk subgroups. All tests were two tailed, and the significance was set at p<0.05. Results: A total of 5121 individuals were consecutively enrolled. The mean age was 47.2 years and females comprised over three-fifths (60.8%) of the participants. With regard to behavioral NCD risks, physical inactivity, unhealthy diet, smoking and alcohol consumption were present in 79.0%, 70.2%, 2.1% and 17.6% of participants, respectively. Moreover, biological risk factors, ie, excess body weight, hypertension, and diabetes were present in 68.4%, 55.8% and 13.0% of participants, respectively. The mean knowledge score was 77.1% and 70.3% of participants demonstrated good knowledge of NCD risk factors. Except for smoking, individuals who showed awareness of various NCD risk factors were found to have significant rates of risky behaviors. Conclusion: Despite sufficient NCD risk knowledge, incongruent lifestyle practices persist, highlighting a crucial concern. This suggests that awareness of NCDs and their risks may influence motivation for change but may not necessarily result in lifestyle modification.

A nightmare of clopidogrel resistance in a resource-limited setting: case report of subacute stent thrombosis.

BACKGROUND: Stent thrombosis, a life-threatening complication of percutaneous coronary intervention (PCI) continues to occur despite effective antiplatelet regimens and improved stenting methods. Noncompliance with dual antiplatelet therapy is the most common etiology; however, in spite of timely and their optimum administration the rates of recurrent myocardial infarction (MI) and stent thrombosis remain high. Clopidogrel resistance is increasingly evoked with elevated risk of anterothrombotic events particularly in the setting of stent implantation. In this case report, we present a case of subacute stent thrombosis associated with clopidogrel resistance in a resource-constrained setting. CASE PRESENTATION: A 60 year old man with a long standing history of hypertension presented with a 6-month history of progressive shortness of breath. Initial electrocardiogram (ECG) revealed T-wave inversion on lateral leads and echocardiogram revealed akinetic basal lateral wall and hypokinetic mid lateral wall with reduced systolic functions. An elective coronary angiography (CAG) revealed a 90% stenosis of mid left anterior descending (LAD) artery and an 80% stenosis on the proximal left circumflex artery. He underwent a successful PCI with a drug-eluting stent implantation to mid LAD. He was discharged in a stable state 48 h post revascularization with dual antiplatelet (clopidogrel and acetylsalicylic acid). Seven days later, he presented with a crushing substernal chest pain. Cardiac enzymes were elevated and ECG revealed anterior ST-elevation MI. An emergency CAG revealed a high thrombus burden with 100% occlusion of mid LAD. Following unsuccessful ballooning, intravenous and intracoronary thrombolysis with tenecteplase was given. A TIMI II flow was achieved and the patient was sent to the coronary care unit. However, 14 h later there was yet a new onset of severe chest pain. A 12-lead ECG previewed anterior ST-elevation MI and the cardiac enzymes were high. Urgent CAG revealed in-stent thrombotic total occlusion of mid LAD. A stent in stent was then implanted and TIMI III flow was restored. Clopidogrel resistance was suspected and the patient was transitioned to ticagrelol. There were no further ischemic events during the remainder of hospitalization and the patient was discharged in a hemodynamically stable state three days later. During follow-up after one and three months, he was fairly stable without any further cardiac events. CONCLUSIONS: Owing to clopidogrel resistance, stent thrombosis in the setting of dual antiplatelet therapy compliance may occur. While in a situation of clopidogrel resistance newer and more potent antiplatelet drugs should be used, their availability and cost remains a significant barrier particularly in the developing world. Nonetheless, a high index of suspicion and timely revascularization is fundamental to restore patency of the thrombosed vessel and confer better risk-adjusted survival rates.

Psychopathology associated with cardiac pacing in Tanzania: A case series.

Emotional disarray linked to interventional procedures may potentially aggravate previous psychiatric conditions or even precipitate new psychopathologies. Despite of the well-known deleterious impact of mental health disorders on cardiac outcomes, psychological disturbances are relatively understudied yet of vital importance to the overall health of post-pacing patients. In this case series we present a spectrum of mental illnesses observed in a cohort of patients who underwent permanent pacemaker implantation in Tanzania's national referral cardiac centre. Five individuals of African origin aged between 58 and 81 years presented to Jakaya Kikwete Cardiac Institute with clinical conditions warranting permanent pacemaker implantation. All five denied prior history of mental illness, however, after thorough psychiatric reviews; organic brain syndrome, panic disorder, brief psychotic disorder, adjustment disorder and major depressive disorder diagnoses were reached. All five were successfully channeled for medical psychotherapy. To conclude, this case series illustrates variable consequences of poor psychological adaptation to implantable cardiac devices, and it underscores the importance of continued psychological evaluation to such patients.

Acute Myocardial Infarction Following the Consumption of Energy Drink in a 28-Year-Old Male: A Case Report.

Excessive intake of energy drinks is increasingly realized to have a detrimental effect on platelet and endothelial functions with resultant hypercoagulable state and consequently increased risk of thrombosis. A 28-year-old man of African origin presented to the emergency department with an 8-hour history of retrosternal chest pain. His symptoms started 4 hours after consuming 5 cans (1250 cc) of an energy drink whose principal ingredients are caffeine, taurine, sugar, and glucuronolactone. His past medical and surgical history was unremarkable, and he had no apparent cardiovascular risk factor. Physical examination was unremarkable; however, electrocardiogram and echocardiogram showed features of anterolateral myocardial infarction (STEMI). Catheterization confirmed a 100% thrombotic occlusion of the proximal left anterior descending (LAD) artery and revascularization with a drug-eluting stent was successful. In conclusion, sudden onset of chest pain following energy drink consumption should raise an index of suspicion for acute coronary syndrome. With the preponderance of data suggesting increased incidence of energy drink-associated coronary events, it is prudent to advocate a limited consumption of such beverages.

Medication Adherence and Blood Pressure Control Among Hypertensive Outpatients Attending a Tertiary Cardiovascular Hospital in Tanzania: A Cross-Sectional Study.

Background: Notwithstanding the availability of effective treatments, asymptomatic nature and the interminable treatment length, adherence to medication remains a substantial challenge among patients with hypertension. Suboptimal adherence to BP-lowering agents is a growing global concern that is associated with the substantial worsening of disease, increased service utilization and health-care cost escalation. This study aimed to explore medication adherence and its associated factors among hypertension outpatients attending a tertiary-level cardiovascular hospital in Tanzania. Methods: The pill count adherence ratio (PCAR) was used to compute adherence rate. In descriptive analyses, adherence was dichotomized and consumption of less than 80% of the prescribed medications was used to denote poor adherence. Logistic regression analyses was used to determine factors associated with adherence. Results: A total of 849 outpatients taking antihypertensive drugs for ≥1 month prior to recruitment were randomly enrolled in this study. The mean age was 59.9 years and about two-thirds were females. Overall, a total of 653 (76.9%) participants had good adherence and 367 (43.2%) had their blood pressure controlled. Multivariate logistic regression analysis showed; lack of a health insurance (OR 0.5, 95% CI 0.3-0.7, p<0.01), last BP measurement >1 week (OR 0.6, 95% CI 0.4-0.8, p<0.01), last clinic attendance >1 month (OR 0.4, 95% CI 0.3-0.6, p<0.001), frequent unavailability of drugs (OR 0.6, 95% CI 0.3-0.9, p = 0.03), running out of medication before the next appointment (OR 0.6, 95% CI 0.4-0.9, p = 0.01) and stopping medications when asymptomatic (OR 0.6, 95% CI 0.4-0.8, p<0.001) to be independent associated factors for poor adherence. Conclusion: A substantial proportion of hypertensive outpatients in this tertiary-level setting had good medication adherence. Nonetheless, observed suboptimal blood pressure control regardless of a fairly satisfactory adherence rate suggests that lifestyle modification plays a central role in hypertension management.

Non-Communicable Disease Risk Factors Among Caregivers of Patients Attending a Tertiary Cardiovascular Hospital in Tanzania.

Background: Notwithstanding the ever-present burden of infectious diseases, the sub-Saharan Africa (SSA) region has experienced a 67% rise in the non-communicable disease (NCD) burden in less than three decades. Furthermore, regardless of the increased recognition of NCDs threat in the region, reliable local estimates and associated drivers are generally lacking. We therefore conducted this cross-sectional study to establish the pattern and correlates of the modifiable NCD risk factors among caregivers of patients attending a tertiary cardiovascular centre in Tanzania. Methods: A cross-sectional survey was conducted at Jakaya Kikwete Cardiac Institute, Dar es Salaam, Tanzania. We used a structured questionnaire bearing a modified WHO STEPwise Approach to NCD Risk Factor Surveillance (STEPS) tool to explore the modifiable behavioral and modifiable biological NCD risk factors. Results: A total of 1063 caregivers were enrolled in this study. The mean age was 40.5 years, and 55.7% were female. Nearly 80% of participants had a good knowledge regarding NCDs and 85.4% had a positive family history of NCDs. Overall, 1027 (96.6%) participants had at least one modifiable NCD risk factor while 510 (48.0%) had three or more (i.e., clustering). With respect to modifiable behavioral NCD risk factors, 34 (3.2%) were tobacco users, 56 (5.3%) had harmful alcohol consumption, 691 (65%) had unhealthy eating behavior, and 820 (77.1%) were physically inactive. Pertaining to modifiable biological NCD risk factors, 710 (66.8%) had excess body weight, 420 (39.5%) had hypertension and 62 (5.8%) were diabetic. Conclusion: A vast majority of caregivers of NCD patients in this tertiary setting were found to have modifiable NCD risk factors with a strong tendency of clustering. These findings call for intensification of both population strategies and targeted group interventions for better control of the NCD threat and its correlates.

Complete heart block ensuing from a metastatic small cell carcinoma: a case report.

INTRODUCTION: Notwithstanding the diagnostic and therapeutic advancements, the incidence of cardiac metastases has increased in recent decades. Lung cancers are the most common primary malignant neoplasms with cardiac metastasis potential. The clinical presentation of cardiac metastases is either silent or vague, and largely depends on the infiltrated location and tumor burden. Although arrhythmias are not uncommon in metastatic cardiac tumors, complete heart block is relatively a rare manifestation. We present a case of complete heart block due to a metastatic small cell carcinoma in a 67-year-old male of African origin. CASE PRESENTATION: A 67-year-old male of African origin from rural Tanzania was referred to us for expert management. He is a retired agromechanic with over 30 years exposure to asbestos-containing brake linings. His past medical history was unremarkable, but the family-social history was evident for a heavy alcohol intake and chronic cigarette smoking. He presented with a 24-week history of progressive shortness of breath and an 8-week history of recurrent syncopal attacks coupled with a significant weight loss. He had normal echocardiographic findings, however, the electrocardiogram showed features of complete heart block. Chest X-ray showed a homogeneous opacification on the right side and computed tomography scan revealed a solid right lung mass with metastases to the liver, heart, bowels, and bone. He underwent bronchoscopy, which revealed an endobronchial mass obstructing the bronchus intermedius. Histological examination of a section of lung biopsy taken during bronchoscopy confirmed the diagnosis of a small cell carcinoma. The patient underwent dual chamber pacemaker implantation with successful sinus rhythm restoration. He made an informed refusal of chemotherapy and inevitably died 18 months post pacing. CONCLUSIONS: Despite the advancements in medical diagnostics and management, lung cancers are often diagnosed in advanced stages, with an inevitable grave prognosis. Small cell carcinoma has the potential to metastasize to the heart, resulting in complete heart block.

Prevalence and risk factors for Subclinical Rheumatic Heart Disease among primary school children in Dar es Salaam, Tanzania: a community based cross-sectional study.

BACKGROUND: Rheumatic heart disease (RHD) is the most common acquired heart disease occurring in children and adolescents. RHD is associated with significant morbidity and mortality particularly in low and middle- income countries (LMICs) where the burden is estimated to be higher compared to high income countries. Subclinical RHD is the presence of valvular lesion diagnosed by echocardiography in a person with no clinical manifestation of RHD. This study aimed at determining the prevalence, types and factors associated with subclinical RHD among primary school children in Dar Es Salaam, Tanzania. METHODS: A descriptive community-based cross-sectional study was conducted in primary school children from February to May 2019. A standardized structured questionnaire was used to collect demographic characteristics, history of upper respiratory tract infections (URTIs), anthropometric measurements, and chest auscultation findings. Moreover echocardiographic screening was done to all children recruited into the study. World Heart Federation echocardiographic classification was used to define the types and prevalence of subclinical RHD. RESULTS: A total of 949 primary school children were enrolled with females being predominant (57.1%). The prevalence of subclinical RHD was 34 per 1000. All the participants had mitral valve disease only whereby 17 had definite disease and 15 had a borderline disease. The associated factors for subclinical RHD were older age of more than 9 years (OR 10.8, 95% CI 1.4-82.2, P = 0.02) having three or more episodes of URTI in previous six months (OR 21, 95% CI 9.6-46, P = 0.00) and poor hygiene (OR 3, 95% CI 1.3-6.8, P = 0.009). CONCLUSION: Subclinical RHD as detected by echocardiographic screening is prevalent in primary school children, uniformly affects the mitral valve, and is associated with potentially modifiable risk factors. Children with a history of more than three episodes of URTI in six months represents a high-risk population that should be targeted for RHD screening.

Burden and correlates of cognitive impairment among hypertensive patients in Tanzania: a cross-sectional study.

BACKGROUND: The evolution of cognitive impairment of vascular origin is increasingly becoming a prominent health threat particularly in this era where hypertension is the leading contributor of global disease burden and overall health loss. Hypertension is associated with the alteration of the cerebral microcirculation coupled by unfavorable vascular remodeling with consequential slowing of mental processing speed, reduced abstract reasoning, loss of linguistic abilities, and attention and memory deficits. Owing to the rapidly rising burden of hypertension in Tanzania, we sought to assess the prevalence and correlates of cognitive impairment among hypertensive patients attending a tertiary cardiovascular hospital in Tanzania. METHODOLOGY: A hospital-based cross-sectional study was conducted at Jakaya Kikwete Cardiac Institute, a tertiary care public teaching hospital in Dar es Salaam, Tanzania between March 2020 and February 2021. A consecutive sampling method was utilized to recruit consented hypertensive outpatients during their scheduled clinic visit. General Practitioner Assessment of Cognition (GPCOG) Score was utilized in the assessment of cognitive functions. All statistical analyses utilized STATA v11.0 software. Pearson Chi square and Student's T-test were used to compare categorical and continuous variables respectively. Logistic regression analyses were used to assess for factors associated with cognitive impairment. Odd ratios with 95% confidence intervals and p-values are reported. All tests were 2-sided and p < 0.05 was used to denote a statistical significance. RESULTS: A total of 1201 hypertensive patients were enrolled in this study. The mean age was 58.1 years and females constituted nearly two-thirds of the study population. About three quarters had excess body weight, 16.6% had diabetes, 7.7% had history of stroke, 5.7% had heart failure, 16.7% had renal dysfunction, 53.7% had anemia, 27.7% had hypertriglyceridemia, 38.5% had elevated LDL, and 2.4% were HIV-infected. Nearly two-thirds of participants had uncontrolled blood pressure and 8.7% had orthostatic hypotension. Overall, 524 (43.6%) of participants had cognitive impairment. During bivariate analysis in a logistic regression model of 16 characteristics, 14 parameters showed association with cognitive functions. However, after controlling for confounders, multivariate analysis revealed ≤primary education (OR 3.5, 95%CI 2.4-5.2, p < 0.001), unemployed state (OR 1.7, 95%CI 1.2-2.6, p < 0.01), rural habitation (OR 1.8, 95%CI 1.1-2.9, p = 0.01) and renal dysfunction (OR 1.7, 95%CI 1.0-2.7, p = 0.04) to have independent association with cognitive impairment. CONCLUSION: This present study underscore that cognitive decline is considerably prevalent among individuals with systemic hypertension. In view of this, it is pivotal to incorporate cognitive assessment in routine evaluation of hypertensive patients.

Human immunodeficiency virus transmission from a 24-year-old woman to her 78-year-old grandmother: a case report.

INTRODUCTION: Since its debut recognition in 1981, human immunodeficiency virus/acquired immunodeficiency syndrome has affected over 77 million people and has resulted in premature cessation of 35.4 million lives worldwide. Commonly, human immunodeficiency virus is transmitted by sexual contact across mucosal surfaces, by sharing of injecting equipment, through contaminated blood transfusions, and by maternal-infant exposure. Nevertheless, accidental transmission incidences involving family members are rare but possible. CASE PRESENTATION: A 78-year-old woman of African descent from Mtwara Region south of Tanzania was referred to us for further evaluation and treatment. She is 30 years postmenopausal and has a 35-year history of hypertension. Her last attendance to our institute was 11 months prior the index visit and she tested negative for human immunodeficiency virus. She came with complaints of weight loss, recurrent fevers, and cough. Her hematological tests revealed leukopenia with lymphocytosis, together with a normocytic normochromic anemia. Enzyme-linked immunosorbent assay for human immunodeficiency virus was positive, and she had a CD4 count of 177 cells/µL. We went back to history taking to identify the potential source of infection. We were informed that for the past 6 months, the 78-year-old lady has been living with her unwell 24-year-old granddaughter who has been divorced. The granddaughter had a history of recurrent fevers, significant weight loss, and a suppurative skin condition. As a way to show love and care, the old lady was puncturing the suppurative lesions with bare hands; then she would suck them to clear away the discharge. We requested to see the young lady, and she tested positive for human immunodeficiency virus. Both were started on tenofovir/lamivudine/dolutegravir combination plus cotrimoxazole 960 mg. The family was in total disarray following these findings. The patient was discharged through infectious diseases department and died of Pneumocystis jirovecii pneumonia 12 weeks later. CONCLUSIONS: Certain sociocultural norms that are believed to express love, care, and togetherness in developing rural communities, particularly Sub-Saharan Africa, have a potential of spreading human immunodeficiency virus, thus warranting prompt transformation.

Obesity epidemic in urban Tanzania: a public health calamity in an already overwhelmed and fragmented health system.

BACKGROUND: Worldwide, the epidemiological and demographic transitions have resulted in nutrition shift characterized by an increased consumption of high energy fast food products. In just over 3 decades, overweight and obesity rates have nearly tripled to currently affecting over a third of the global population. Notwithstanding the ever present under-nutrition burden, sub Saharan Africa (SSA) is witnessing a drastic escalation of overweight and obesity. We aimed to explore the prevalence and associated factors for obesity among residents of Dar es Salaam city in Tanzania. METHODS: Participants from this study were recruited in a community screening conducted during the Dar es Salaam International Trade Fair. Sociodemographic and clinical data were gathered using a structured questionnaire during enrollment. Dietary habits and anthropometric measurements were assessed using standard methods. All statistical analyses utilized STATA v11.0 software. Pearson Chi square and Student's T-test were used to compare categorical and continuous variables respectively. Logistic regression analyses were used to assess for factors associated with BMI ≥ 25. All tests were 2-sided and p < 0.05 was used to denote a statistical significance. RESULTS: A total of 6691 participants were enrolled. The mean age was 43.1 years and males constituted 54.2% of all participants. Over two-thirds of participants were alcohol consumers and 6.9% had a positive smoking history. 88.3% of participants were physically inactive, 4.7% had a history of diabetes mellitus and 18.1% were known to have elevated blood pressure. Overweight and obesity were observed in 34.8 and 32.4% of participants respectively. Among overweight and obese participants, 32.8% had a misperception of having a healthy weight. Age ≥ 40, female gender, a current working status, habitual breakfast skipping, poor water intake, high soft drink consumption, regular fast food intake, low vegetable and fruit consumption, alcohol consumption and hypertension were found to be independent associated factors for obesity. CONCLUSION: Amidst the ever present undernutrition in SSA, a significant proportion of participants had excess body weight. Concomitantly, the rates of physical inactivity and unhealthy eating are disproportionately high in Dar es Salaam. In view of this, community-based and multilevel public health strategies to promote and maintain healthy eating and physical activity require an urgent step-up in urban Tanzania.

Knowledge of cardiovascular risk factors among caretakers of outpatients attending a tertiary cardiovascular center in Tanzania: a cross-sectional survey.

BACKGROUND: Health literacy on cardiovascular diseases (CVDs) plays an effective role in preventing or delaying the disease onset as well as in impacting the efficacy of their management. In view of the projected low health literacy in Tanzania, we conducted this cross-sectional survey to assess for CVD risk knowledge and its associated factors among patient escorts. METHODS: A total of 1063 caretakers were consecutively enrolled in this cross-sectional study. An adopted questionnaire consisting of 22 statements assessing various CVD risk behaviors was utilized for assessment of knowledge. Logistic regression analyses were performed to assess for factors associated with poor knowledge of CVD risks. RESULTS: The mean age was 40.5 years and women predominated (55.7%). Over two-thirds had a body mass index (BMI) ≥25 kg/m2, 18.5% were alcohol drinkers, 3.2% were current smokers, and 47% were physically inactive. The mean score was 78.2 and 80.0% had good knowledge of CVD risks. About 16.3% believed CVDs are diseases of affluence, 17.4% thought CVDs are not preventable, and 56.7% had a perception that CVDs are curable. Low education (OR 2.6, 95%CI 1.9-3.7, p < 0.001), lack of health insurance (OR 1.5, 95%CI 1.1-2.3, p = 0.03), and negative family history of CVD death (OR 2.2, 95%CI 1.4-3.5, p < 0.001), were independently associated with poor CVD knowledge. CONCLUSIONS: In conclusion, despite of a good level of CVD knowledge established in this study, a disparity between individual's knowledge and self-care practices is apparent.

Burden and correlates of atrial fibrillation among hypertensive patients attending a tertiary hospital in Tanzania.

BACKGROUND: Atrial fibrillation (AF) is the most common supra ventricular cardiac arrhythmia, which presents with variety of clinical symptoms. Hypertension increases risk of developing Atrial fibrillation by 1.5 fold. Together Atrial fibrillation and hypertension doubles the risk of morbidity and mortality. We aimed to determine the prevalence of AF and describe associated factors among hypertensive patients attending tertiary hospital in Tanzania. METHODS: A cross-sectional hospital-based study, involving 391 hypertensive patients visiting the Jakaya Kikwete Cardiac Institute was conducted between October to December 2017. Categorical variables were analyzed using chi square while student t- test was used to analyze continuous variables. Multivariate logistic regression analysis was performed to determine factors associated with AF. All analysis was two sided and p- value of < 0.05 was used to be not significant. RESULTS: AF was detected in 40 (10.2%) patients. Atrial fibrillation was associated with BMI ≥ 25 (OR 4.4, 95% CI 1.1-7.7, p-value 0.02), ejection fraction < 50% (OR 3.0, 95%CI 1.1-8.2, p-value 0.03), Left Atrial diameter > 40 mm (OR 9.4,95%CI 2.1-43.2, p-value < 0.01) and eGFR< 60 (OR 2.9, 95%CI 1.1-7.8, p-value 0.04). CONCLUSION: Atrial fibrillation is considerably prevalent among the hypertensive sub-population. Prompt diagnosis and timely management is vital to prevent complications and premature mortality.

A Case of Wellens Syndrome in a 30-Year-Old Woman From Sub-Saharan Africa: A Perplexing Clinical Entity With Invaluable Lessons.

With an estimated contribution of up to 6% of all acute coronary events, young adults are experiencing an escalating burden and mortality attributable to coronary artery disease (CAD) worldwide. Wellens syndrome, a preinfarction clinical entity with distinctive electrocardiographic (ECG) features and high propensity for extensive anterior wall infarctions, affects about 15% of unstable angina subpopulation. We report challenges and lessons learnt from the first ever documented case of Wellens syndrome in Tanzania. A 30-year-old female of African descent was referred to us from an upcountry zonal referral hospital for etiological determination of chest pain and expert management. Her medical history was unremarkable, and she had no apparent risk factors for CAD. She presented with a 7-day history of ongoing sharp central chest pain that was radiating to the neck and jaws and relieved momentarily by morphine. She had stable vitals with an unremarkable systemic examination; however, a 12-lead ECG revealed deeply inverted T-waves on leads V2 through V4. Based on our extensive history and physical examination we came up with a diagnosis of type B Wellens syndrome with impending anterior wall myocardial infarction. She underwent cardiac catheterization that revealed a nonthrombogenic severe subocclusive (>95%) mid left anterior descending artery stenosis. Subsequently, angioplasty was performed successfully with a resolute integrity stent, and TIMI III flow was achieved. To conclude, despite its relative frequency, physicians' awareness of Wellens syndrome pathognomonic ECG features is of paramount importance to curb its attributable morbidity and mortality.

Massive Bilateral Hydroureteronephrosis and End-Stage Renal Disease Ensuing From Chronic Schistosomiasis: A Case Report.

Globally, schistosomal infections affect over 200 million people resulting in the loss of 70 million disability-adjusted life years. In the sub-Saharan Africa region, where over 85% of the global schistosomal infections are found, it is estimated that about 120 million people become symptomatic, over 20 million have severe disease, and nearly 200 000 die every year. Renal impairment is a severe consequence of schistosomiasis occurring in about 6% of all infected individuals and in 15% of those with the hepatosplenic form. We present a case of massive bilateral hydroureteronephrosis and end-stage renal disease resulting from chronic schistosomiasis in a 38-year-old male of African origin. A 38-year-old male rice farmer of African origin presented with a history of elevated blood pressure, abdominal swelling, and reduced urinary output for about 10 months. Abdominal examination revealed an intraabdominal mass measuring 30 cm × 17 cm extending from the right hypochrondrium region downward to right inguinal outward to umbilicus crossing the midline. He had an estimated glomerular filtration rate of 3.9 mL/min, hemoglobin of 6.78 g/dL, and had multiple electrolyte abnormalities. A computed tomography intravenous urogram scan of the abdomen revealed hepatomegaly (18 cm), bilateral renal enlargement with hydroureteronephrosis, and multiple calcifications on the urinary bladder. A rectal biopsy isolated haematobium eggs and confirmed the diagnosis. Urinary schistosomiasis can have distressing effects on the urinary system in particular and survival prospects in general. In view of this, extensive evaluation of the genitourinary system is pivotal for timely diagnosis and prompt management particularly in residents of schistosoma-endemic communities presenting with obstructive uropathy.

Factors influencing left ventricular ejection fraction in patients with coronary microvascular disease and obstructive coronary artery disease.

OBJECTIVE: The aim of our research was to evaluate the relationship involving left ventricular ejection fraction, low density lipoprotein, B-type natriuretic peptide, Troponin I and coronary flow reserve, and to determine the predictors of left ventricular ejection fraction in patients with coronary microvascular disease and obstructive coronary artery disease, and in patients with coronary microvascular disease. RESULTS: The mean age was 58.5 ± 12.5 years. In patients with obstructive coronary disease and coronary microvascular disease we found low density lipoprotein-c had significant inverse relationship with left ventricular ejection fraction, left ventricular ejection fraction also had significant negative relationship with B-type natriuretic peptide, and Troponin-I. While a significant direct relationship turned out to be observed linking left ventricular ejection fraction with coronary flow reserve. Left ventricular ejection fraction had significant negative relationship with low density lipoprotein, and B-type natriuretic peptide in patients with obstructive coronary artery disease only. Age, blood pressure, lipid levels, red cell distribution width, glycated hemoglobin, symptoms, New York heart association classification, alcohol drinking, hypertension, diabetes mellitus, troponin levels and B-type natriuretic peptide were the predictors for left ventricular ejection fraction in coronary microvascular disease patients.

Medication adherence and survival among hospitalized heart failure patients in a tertiary hospital in Tanzania: a prospective cohort study.

OBJECTIVE: Management of heart failure is complex and multifaceted but adherence to medications remains the cornerstone of preventing avoidable readmissions, premature deaths, and unnecessary healthcare expenses. Despite of evidence-based efficacy on anti-failure drugs, poor adherence is pervasive and remains a significant barrier to improving clinical outcomes in heart failure population. RESULTS: We enrolled 459 patients with diagnosis of heart failure admitted at a tertiary cardiovascular hospital in Dar es Salaam, Tanzania. The mean age was 46.4 years, there was a female predominance (56.5%), 67.5% resided in urban areas and 74.2% had primary education. Of the 419 participants eligible for assessment of medication adherence, 313 (74.7%) had poor adherence and 106 (25.3%) had good adherence. Possession of a health insurance was found to be the strongest associated factor for adherence (adjusted OR 8.7, 95% CI 4.7-16.0, p < 0.001). Participants with poor adherence displayed a 70% increased risk for rehospitalization compared to their counterparts with good adherence (adjusted RR 1.7, 95% CI 1.2-2.9, p = 0.04). Poor adherence was found to be the strongest predictor of early mortality (HR 2.5, 95% CI 1.3-4.6, p < 0.01). In conclusion, Poor medication adherence in patients with heart failure is associated with increased readmissions and mortality.

Takayasu Arteritis Mistaken for Epilepsy: A Case Presenting With Convulsive Syncope.

Takayasu arteritis (TA) is a chronic inflammatory disease characterized by granulomatous vasculitis that predominantly manifests as panaortitis. This occlusive thromboaortopathy lacks pathognomonic features often resulting in a diagnostic dilemma leading to its under-recognition, misdiagnosis and delayed management. Although neurological manifestations are not uncommon in TA, convulsive syncope as an initial clinical presentation is extremely rare. We report a case of convulsive syncope as a manifesting symptom of TA. A 17-year-old male patient of African origin was referred to us from an upcountry regional hospital with a diagnosis of medically intractable epilepsy for cardiovascular review. He presented with a 28-week history of generalized tonic-clonic seizures followed by loss of consciousness. He denied history of recurrent headaches, fever, visual disturbances, arthralgias, claudication or unintentional weight loss. Physical examination revealed feeble left-sided brachial and radial pulses, elevated blood pressure, differences in blood pressure between arms and left-sided carotid and vertebral bruits. Computed tomography angiogram of his thoracic and abdominal aorta revealed changes suggestive of a diffuse arteritis. Additionally, magnetic resonance angiogram of the brain revealed total occlusion of the left common carotid, left internal carotid, left external carotid and left vertebral arteries. Based on the physical examination and radiological findings, we reached a diagnosis of TA. He was prescribed dexamethasone, methotrexate, acetylsalicylic acid and amlodipine. He had a remarkable recovery and was seizure-free for the last 5 months after discharge. TA may manifest with convulsive syncope mimicking epilepsy. Despite its rarity, presentations of this nature continue to challenge clinicians resulting in delayed diagnosis with irreversible life-threatening consequences to patients. In view of this, physicians should strive to take detailed history and perform thorough physical examination so as to timely pick the characteristic signs of TA especially in patients presenting with unanticipated symptoms.

Suicide Attempt Following Pacemaker Implantation in an Eighty-Three-Year-Old Male: A Case Report.

As the global population ages, cardiac pacing procedures are rising exponentially to keep pace with the increasing incidence of bradyarrhythmias. The efficacy of pacemakers is well established, but recipients may have poor psychosocial adaptation leading to development or exacerbation of mental disorders, that may manifest with anxiety, depressive symptoms or rarely suicidal tendencies. An 83-year-old male of African descent was referred to us for evaluation and expert management. He came with chief complaints of general body malaise, light-headedness, chest pain and fainting spells for about 6 months. He was diagnosed with hypertension 4 years prior, and there was no history of mental illness in the patient or his family. Echocardiography (ECHO) revealed features of hypertensive heart disease while electrocardiogram (ECG) showed features of third-degree heart block. He underwent successful pacing with a resultant ventricular paced rhythm. The patient was stable and symptom free post pacing, but on the fourth day he jumped off the window of the ward in the hospital's second floor. Post suicide attempt examination revealed epistaxis, right periorbital hematoma with a temporal lacerated wound and deformed ankles bilaterally. ECG showed a ventricular paced rhythm and the chest radiograph showed an intact pacemaker. Ophthalmological review was evident for right sided blepharospasm with massive chemosis and bilateral constricted reactive pupils. Radiological investigations showed right orbital fracture, stable C5 and C6 fractures, and bilateral bimalleolar fractures with ankle dislocation. Neurosurgical review was unremarkable and psychiatric review could not be performed. The patient died 18 h after the suicide attempt incidence. Emotional disturbances post pacing impairs the quality of life and in the worst case scenario could lead to unanticipated cessation of life. In view of this, thorough evaluation and monitoring of the patient's psychological well-being both pre and post pacing is paramount.
