Infections in early life and premature acute coronary syndrome: A case-control study

BACKGROUND

Infections in young children may affect the vasculature and initiate early atherosclerosis. Whether infections experienced in childhood play a part in adult clinical cardiovascular disease remains unclear. We investigated the association between infections in early life and the occurrence of premature coronary heart disease.

METHODS

We conducted a population-based case-control study of 153 patients with a first acute coronary syndrome before the age of 56 years and 153 age- and sex-matched controls. Any history of severe infections in childhood and adolescence was obtained, together with clinical and laboratory measurements and other cardiovascular risk factors. We developed an infection score for the overall burden of early life infections. Conditional logistic regression was used to assess the associations.

RESULTS

Infections experienced in early life increased the risk of acquiring acute coronary syndrome at a young age with an odds ratio (OR) of 2.67 (95% confidence interval (CI) 1.47-4.83, p = 0.001). After adjustments for traditional risk factors, lifestyle, dietary patterns, socio-economic status and parental history of cardiovascular events, these associations remained significant and changed only slightly. There was an indication for an interaction between infections in early life and current cardiovascular risk (Framingham Risk Score (FRS); p-interaction = 0.052). Within participants with a low FRS (<10%), the OR of early life infection for acute coronary syndrome was 1.49 (95% CI 0.72-3.08, p = 0.283); within participants with an intermediate FRS (10-20%), the OR was 4.35 (95% CI 1.60-11.84, p = 0.004); and within participants with a high FRS (>20%), the OR 10.00 (95% CI 1.21-82.51, p = 0.032).

CONCLUSION

Infections in early life may partly explain premature coronary heart disease in adulthood and may potentiate traditional cardiovascular risk factor effects.

Predictors of medium-term mortality in patients hospitalised with coronary artery disease in a resource-limited South-East Asian setting

Objective

To measure medium-term outcomes and determine the predictors of mortality in patients with coronary artery disease (CAD) both during and after hospitalisation in a resource-limited South-East Asian setting.

Methods

From February 2013 to December 2014, we conducted a prospective observational cohort study of 477 patients admitted to Makassar Cardiac Center, Indonesia, with acute coronary syndrome and stable CAD. We actively obtained data on clinical outcomes and after-discharge management until April 2017. Multivariable Cox proportional hazard analysis was performed to examine predictors for our primary outcome, all-cause mortality.

Results

From hospital admission, patients were followed over a median of 18 (IQR 6-36) months; in total 154 (32.3%) patients died. More patients with acute myocardial infarction died in the hospital compared with patients with unstable and stable angina (p=0.002). Over the total follow-up, there was a difference in mortality between non-ST-segment elevation myocardial infarction (n=41, 48.2%), ST-segment elevation myocardial infarction (n=65, 30.8%), unstable angina (n=18, 26.5%) and stable coronary artery disease (n=30, 26.5%) groups (p=0.007). The independent predictors of all-cause mortality were hyperglycaemia on admission (HR 1.55 (95% CI 1.12 to 2.14), p=0.008), heart failure/Killip class ≥2 (HR 2.50 (95% CI 1.76 to 3.56), p<0.001), estimated glomerular filtration rate <60 mL/min (HR 1.77 (95% CI 1.26 to 2.50), p=0.001), no revascularisation (percutaneous coronary intervention/coronary artery bypass grafting) (HR 2.38 (95% CI 1.31 to 4.33), p=0.005) and poor adherence to after-discharge medications (HR 10.28 (95% CI 5.52 to 19.16), p<0.001). Poor medication adherence predicted postdischarge mortality and did so irrespective of underlying CAD diagnosis (p interaction=0.88).

Conclusions

Patients with CAD in a poor South-East Asian setting experience high in-hospital and medium-term mortality. The initial severity of the disease, lack of access to guidelines-recommended therapy and poor adherence to after-discharge medications are the main drivers for excess mortality. Improved access to early and late hospital care and patient education should be prioritised for better survival.

Tele-ECG consulting and outcomes on primary care patients in a low-to-middle income population: the first experience from Makassar telemedicine program, Indonesia

Background

Telemedicine has been a popular tool to overcome the lack of access to healthcare facilities, primarily in underprivileged populations. We aimed to describe and assess the implementation of a tele-electrocardiography (ECG) program in primary care settings in Indonesia, and subsequently examine the short- and mid-term outcomes of patients who have received tele-ECG consultations.

Methods

ECG recordings from thirty primary care centers were transmitted to Makassar Cardiac Center, Indonesia from January to July 2017. We cross-sectionally measured the performance of this tele-ECG program, and prospectively sent a detailed questionnaire to general practitioners (GPs) at the primary care centers. We performed follow-up at 30 days and at the end of the study period to assess the patient outcomes.

Results

Of 505 recordings, all (100%) ECGs were qualified for analysis, and about half showed normal findings. The mean age of participants was 53.3 ± 13.6 years, and 40.2% were male. Most (373, 73.9%) of these primary care patients exhibited manifested CVD symptom with at least one risk factor. Male patients had more ischemic ECGs compared to women (p < 0.01), while older age (> 55 years) was associated with ischemic or arrhythmic ECGs (p < 0.05). Factors significantly associated with a normal ECG were younger age, female gender, lower blood pressure and heart rate, and no history of previous cardiovascular disease (CVD) or medication. More patients with an abnormal ECG had a history of hypertension, known diabetes, and were current smokers (p < 0.05). Of all tele-consultations, GPs reported 95% of satisfaction rate, and 296 (58.6%) used tele-ECG for an expert opinion. Over the total follow-up (14 ± 6.6 months), seven (1.4%) patients died and 96 (19.0%) were hospitalized for CVD. Of 88 patients for whom hospital admission was advised, 72 (81.8%) were immediately referred within 48 h following the tele-ECG consultation.

Conclusions

Tele-ECG can be implemented in Indonesian primary care settings with limited resources and may assist GPs in immediate triage, resulting in a higher rate of early hospitalization for indicated patients.

The readiness of public primary health care (PUSKESMAS) for cardiovascular services in Makasar city, Indonesia

BACKGROUNDS

The increasing burden of cardiovascular disease (CVD) has become a major challenge globally, including in Indonesia. Understanding the readiness of primary health care facilities is necessary to confront the challenge of providing access to quality CVD health care services. Our study aimed to provide information regarding readiness to deliver CVD health services in public primary health care namely Puskesmas.

METHODS

The study questionnaire was adapted from the World Health Organization (WHO) Service Availability and Readiness Assessment (SARA), modified based on the package of essentials for non-communicable disease (PEN) and the Indonesian Ministry of health regulation. Data were collected from all Puskesmas facilities (N = 47) located in Makassar city. We analysed relevant data following the WHO-SARA manual to assess the readiness of Puskesmas to deliver CVD services. Human resources, diagnostic capacity, supporting equipment, essential medication, infrastructure and guidelines, and ambulatory services domain were assessed based on the availability of each tracer item in a particular domain. The mean domain score was calculated based on the availability of tracer items within each domain. Furthermore, the means of all domains' scores are expressed as an overall readiness index. Higher scores indicate greater readiness of Puskesmas to deliver CVD-related health care.

RESULTS

Puskesmas delivers health promotion, disease prevention, and prompt diagnosis for cardiovascular-related diseases, including hypertension, diabetes, coronary heart disease (CHD), and stroke. Meanwhile, basic treatments were observed in the majority of the Puskesmas. Long-term care for hypertension and diabetes patients and rehabilitation for CHD and stroke were only observed in a few Puskesmas. The readiness score of Puskesmas to deliver CVD health care ranged from 60 to 86 for. Furthermore, there were 11 Puskesmas (23.4%) with a score below 75, indicating a sub-optimal readiness for delivering CVD health services. A shortage of essential medicines and a low capacity for diagnostic testing were the most noticeable shortcomings leading to suboptimal readiness for high-quality CVD health services.

CONCLUSION

Close cooperation with the government and other related stakeholders is required to tackle the identified shortcomings, especially the continuous monitoring of adequate supplies of medicines and diagnostic tools to achieve better CVD care for patients in Indonesia.

Characteristics and the average 30-day and 6-month clinical outcomes of patients hospitalised with coronary artery disease in a poor South-East Asian setting: the first cohort from Makassar Cardiac Center, Indonesia

OBJECTIVE

To provide a detailed description of characteristics at hospital admission and clinical outcomes at 30-day and 6-month follow-up in patients hospitalised with coronary artery disease (CAD) in a poor South-East Asian setting.

DESIGN

Prospective observational cohort study.

SETTING

From February 2013 to December 2014, in Makassar Cardiac Center, Indonesia.

PARTICIPANTS

477 patients with CAD (acute coronary syndrome and stable CAD).

OUTCOME MEASURES

All-cause mortality and major adverse cardiovascular events (MACE).

RESULTS

Out of 477 patients with CAD, the proportion of young age (<60 years) was 53.9% and 72.7% were male. At admission, 44.2% of patients were diagnosed with ST-segment elevation myocardial infarction (STEMI), 38.6% with diagnosis or signs of heart failure and 75.1% had previous hypertension. Out of 211 patients with STEMI, only 4.7% had been treated with primary percutaneous coronary intervention (PCI) and 6.2% received thrombolysis. The time lapse from symptom onset to hospital admission was 26.8 (IQR 10.0-48.0) hours, and 19.1% of all patients had undergone either PCI or coronary artery bypass graft. The survival rate at 6 months was 78.9%. The rates of all-cause mortality at 30 days and 6 months were 13.4% and 7.3%, respectively; the rate of composite MACE at 30 days was 26.2% and 18.0% at 6 months.

CONCLUSIONS

Patients with CAD from a poor South-East Asian setting present themselves with predominantly unstable conditions of premature CAD. These patients show relatively severe illness, have significant time delay from symptom onset to admission or intervention, and most do not receive the guidelines-recommended treatment. Awareness of symptoms, prompt initial management of acute CVD, well-established infrastructures and resources both in primary and secondary hospital for CVD should be improved to reduce the high rates of 30-day and 6-month mortality and adverse outcomes in this population.

Adherence to guideline recommendations for coronary angiography in a poor South-East Asian setting: Impact on short- and medium-term clinical outcomes

In South-East Asian populations and particularly in Indonesia, access to coronary angiography (CAG) is limited. We aimed to assess the adherence for undergoing CAG for indicated patients, according to the guideline recommendations. We then examined whether this adherence would have an impact on patients' short- and medium-term mortality and morbidity. We consecutively enrolled 474 patients with acute and stable coronary artery disease who had indication for CAG at Makassar Cardiac Center, Indonesia from February 2013 to December 2014. We found that adherence to CAG recommendation in poor South-East Asian setting is low. Of 474 recommended patients, only 273 (57.6%) underwent the procedure. Factors for not undergoing CAG were: older age, female gender, low educational and socio-economic status, and insurance type. While reasons for patients refusing CAG and subsequent intervention included fear, symptoms reduction, and lack of trust concerning the procedure benefit. During follow-up (median 19 (IQR 6-39.3) months), 155 (32.7%) patients died, and 259 (54.6%) experienced at least one adverse event. Adherence to CAG recommendation was associated with a significantly lower short- and medium-term mortality, independent of revascularization and other potential confounders. In sub-group analysis, adhered patients "with revascularization" had significantly better outcomes compared to the "non-revascularization" and "not adhere" groups.

Pregnancy-related conditions and premature coronary heart disease in adult offspring

Objective

To investigate the association between complications during pregnancy and premature coronary heart disease in adult offspring.

Methods

We conducted a population-based case-control study of 153 Indonesian patients with a first acute coronary syndrome (ACS) (age ≤55 years) and 153 age-matched and sex-matched controls. Data on complications during pregnancy (high blood pressure, preterm delivery) and maternal infections in pregnancy were obtained, together with sociodemographic data, clinical profiles, laboratory measurements and adulthood cardiovascular disease (CVD) risk factors at hospital admission or enrolment. Conditional logistic regression was performed to assess the association between overall pregnancy complications, and specific groupings of complications and premature ACS.

Results

Pregnancy-related hypertension and infection were more common in mothers of cases than controls. Pregnancy complications were associated with premature offspring ACS (OR 2.9, 95% CI 1.4 to 6.0, p=0.004), and the association persisted in fully adjusted analyses (OR_adjusted 4.5, 1.1 to 18.1, p=0.036). In subgroup analyses, pregnancy-related high blood pressure (OR_adjusted 5.0, 1.0 to 24.7, p=0.050) and maternal infections (OR_adjusted 5.2, 1.1 to 24.2, p=0.035) were associated with offspring ACS.

Conclusions

Offspring of mothers with complications during pregnancy have an increased risk for premature ACS in adulthood, which may be of particular relevance in populations in transition, where the incidence of both pregnancy-related morbidity and CVD are high.

Exploring the link between cardiovascular risk factors and manifestations in latent tuberculosis infection: a comprehensive literature review

BACKGROUND

The global burden of tuberculosis (TB) and cardiovascular disease (CVD) is overt, and the prevalence of this double burden disease remains steadily rising, particularly in low- and middle-income countries. This review aims to explore the association between latent tuberculosis infection (LTBI) and the development of cardiovascular diseases and risk factors. Furthermore, we elucidated the underlying pathophysiological mechanisms that contribute to this relationship.

MAIN BODY

Approximately 25% of the global population carries a dormant form of tuberculosis (TB) infection. During this latent stage, certain subsets of mycobacteria actively reproduce, and recent research suggests that latent TB infection (LTBI) is connected to persistent, long-term low-grade inflammation that can potentially contribute to the development of atherosclerosis and cardiovascular disease (CVD). The presence of LTBI can be confirmed through a positive result on either a tuberculin skin test (TST) or an interferon-gamma release assay (IGRA). Several plausible explanations for the association between LTBI and CVD include increased inflammation, autoimmunity related to heat shock proteins (HSP), and the presence of pathogens within the developing atherosclerotic plaque. The most commonly observed cardiovascular events and risk factors associated with LTBI are acute myocardial infarction, coronary artery stenosis, diabetes mellitus, and hypertension.

CONCLUSIONS

This article highlights the critical role of LTBI in perpetuating the tuberculosis disease cycle and its association with cardiovascular risk factors. Chronic and persistent low inflammation underlined the association. Identifying high-risk LTBI patients and providing targeted preventive medication are crucial strategies for global TB eradication and interrupting transmission chains.

Stress hyperglycemia and poor outcomes in patients with ST-elevation myocardial infarction: a systematic review and meta-analysis

Background

Hyperglycemia, characterized by elevated blood glucose levels, is frequently observed in patients with acute coronary syndrome, including ST-elevation myocardial infarction (STEMI). There are conflicting sources regarding the relationship between hyperglycemia and outcomes in STEMI patients. We aimed to compile evidence to assess the association between hyperglycemia and adverse outcomes.

Methods

We conducted a comprehensive search for articles on PubMed and Embase using search strategies which yielded 4,061 articles. After full-text screening, 66 articles were included for systematic review, and 62 articles were further selected for meta-analysis.

Results

The 66 included articles spanned the years 2005-2023. Of these, 45 articles reported admission blood glucose, 13 articles used HbA1c, and 7 articles studied fasting blood glucose. Most studies defined STEMI with primary PCI as their inclusion criteria. Mortality was the most often outcome reported related to hyperglycemia. Overall, 55 (83.3%) studies were at low risk of bias. Both admission and fasting blood glucose were significantly related to short- and long-term mortality after STEMI, with a pooled risk ratio (RR) of 3.02 (95%CI: 2.65-3.45) and 4.47 (95% CI: 2.54-7.87), respectively. HbA1c showed substantial association with long-term mortality (HR 1.69, 95% CI: 1.31-2.18)) with a pooled RR of 1.58 (95% CI 1.26-1.97). In subsequent analyses, admission hyperglycemia was associated with an increased risk of reinfarction (pooled RR 1.69, 95% CI 1.31-2.17), heart failure (pooled RR 1.56, 95% CI: 1.37-1.77), cardiogenic shock (pooled RR 3.68, 95% CI 2.65-5.11), repeat PCI or stent thrombosis (pooled RR 1.99, 95% CI 1.21-3.28), and composite major adverse cardiac and cerebrovascular events (MACCE) (pooled RR 1.99, 95% CI: 1.54-2.58).

Conclusions

Our study demonstrated that hyperglycemia has a strong association with poor outcomes after STEMI. Admission and fasting blood glucose are predictors for short-term outcomes, while HbA1c is more appropriate for predicting longer-term outcomes in STEMI patients.

Inhibitory effect of MLC901 on axonal demyelination in experimental animals undergoing circumferential lumbal stenosis by increasing transforming growth factor-β1 levels

Study Design

Experimental study using circumferential lumbar stenosis (CLS) rat model.

Purpose

To investigate the effect of MLC901 administration on transforming growth factor (TGF)-β1 level and the degree of axonal demyelination in the CLS rat model.

Overview of Literature

CLS is common in older adults, causing neuropathic pain that impairs daily functioning. TGF-β1 plays an essential role in nerve regeneration and reducing axonal demyelination in CLS. MLC901, a traditional therapeutic formula, has shown promise in preclinical studies, including modulating proinflammatory cytokines. While MLC901's effect on serum TGF-β1 levels in the CLS rat model has been explored, its impact on tissue TGF-β1 expression remains understudied.

Methods

Rats were randomly allocated into one of six groups: no CLS (baseline), CLS only (pretreatment), short treatment (1 day) with MLC901, short treatment with placebo, longer treatment (7 days) with MLC901, and longer treatment with placebo. The CLS model was induced by laminectomy at the lumbar 5th vertebra, followed by teflon insertion around the dura mater. Serum TGF-β1 levels were measured using enzyme-linked immunosorbent assay. Tissue TGF-β1 expression and the degree of axonal demyelination were assessed by immunohistochemistry and histopathology, respectively.

Results

Long treatment MLC901 group had significantly higher serum TGF-β1 levels than the pretreatment group (p<0.001). Long treatment MLC901 group also exhibited the highest TGF-β1 tissue expression among all treatment groups, including the baseline group (p=0.013). Axonal demyelination was lowest in the long treatment MLC901 group, indicated by the highest number of Schwann cells (p<0.001), the fewest inflammatory cells (except versus baseline) (p=0.001), and the fewest vacuoles (except versus baseline) (p=0.015).

Conclusions

MLC901 can inhibit axonal demyelination in experimental animals undergoing CLS surgery by upregulating TGF-β1 levels. MLC901 has the potential to be used as an adjuvant therapy in CLS surgery.

Comparison of Pain, Cortisol, and IL6 Levels Pre and Post SEFT in Stage III B Cervical Cancer Patients

OBJECTIVE

The objective of the study is to assess the impact of Spiritual Emotional Freedom Technique (SEFT) intervention on pain severity, cortisol, and IL6 levels in stage III B cervical cancer patients undergoing chemoradiation.

METHODS

A quasi-experimental study with a one-group pre-test post-test design was conducted at Gatot Soebroto Hospital, Jakarta, Indonesia, focusing on stage III B cervical cancer patients who received chemoradiation. Pain severity was quantified using the Numeric Rating Scale (NRS), while cortisol and IL6 levels were determined via serum specimen collection and ELISA analysis. Statistical analysis revealed significant disparities in pain severity, cortisol levels, and IL6 levels pre- and post-intervention. A significant correlation emerged between pain severity, cortisol, and IL6 levels (p<0.001).

RESULT

The average pre-intervention pain severity was 4.5 and the average post-intervention pain severity was 1.6. The average pre-intervention cortisol level was 632.9 and the average post-intervention cortisol level was 305.3 (p-value <0.001). The average pre-intervention IL6 level was 260.1 and the average post-intervention IL6 level was 106.7.

CONCLUSION

The SEFT proves highly effective in alleviating pain among cervical cancer patients undergoing chemoradiation.

In-hospital mortality of patients with acute coronary syndrome (ACS) after implementation of national health insurance (NHI) in Indonesia

BACKGROUND

The National Health Insurance (NHI) was implemented in Indonesia in 2014, and cardiovascular diseases are one of the diseases that have overburdened the healthcare system. However, data concerning the relationship between NHI and cardiovascular healthcare in Indonesia are scarce. We aimed to describe changes in cardiovascular healthcare after the implementation of the NHI while determining whether the implementation of the NHI is related to the in-hospital mortality of patients with acute coronary syndrome (ACS).

METHODS

This is a retrospective comparative study of two cohorts in which we compared the data of 364 patients with ACS from 2013 to 2014 (Cohort 1), before and early after NHI implementation, with those of 1142 patients with ACS from 2018 to 2020 (Cohort 2), four years after NHI initiation, at a tertiary cardiac center in Makassar, Indonesia. We analyzed the differences between both cohorts using chi-square test and Mann-Whitney U test. To determine the association between NHI and in-hospital mortality, we conducted multivariable logistic regression analysis.

RESULTS

We observed an increase in NHI users (20.1% to 95.6%, p < 0.001) accompanied by a more than threefold increase in patients with ACS admitted to the hospital in Cohort 2 (from 364 to 1142, p < 0.001). More patients with ACS received invasive treatment in Cohort 2, with both thrombolysis and percutaneous coronary intervention (PCI) rates increasing more than twofold (9.2% to 19.2%; p < 0.001). There was a 50.8% decrease in overall in-hospital mortality between Cohort 1 and Cohort 2 (p < 0.001).

CONCLUSIONS

This study indicated the potential beneficial effect of universal health coverage (UHC) in improving cardiovascular healthcare by providing more accessible treatment. It can provide evidence to urge the Indonesian government and other low- and middle-income nations dealing with cardiovascular health challenges to adopt and prioritize UHC.

Low Attainment of Treatment Targets for Cardiovascular Risk Factors in Indonesian Adults With Established Coronary Artery Disease

RATIONALE

Established coronary artery disease (CAD) patients are at increased risk for recurrence of cardiovascular events and mortality due to non-attainment of recommended risk factor control targets.

OBJECTIVE

We aimed to evaluate the attainment of treatment targets for risk factor control among CAD patients as recommended in the Indonesian CVD prevention guidelines.

METHODS

Patients were consecutively recruited from the Makassar Cardiac Center at Wahidin Sudirohusodo Hospital, Indonesia. Targets for systolic blood pressure (SBP < 140 mmHg), low-density lipoprotein-cholesterol (LDL-C < 1.8 mmol/L), body mass index (BMI: 20-25 kg/m2), non-smoking status and antithrombotic use were assessed according to the national guideline. Attainment levels were evaluated in CAD population subgroups using logistic regression to identify patients who required more intensive monitoring.

RESULTS

A total of 395 CAD patients (median age: 57 years (IQR: 49-65), 63.8% men) were recruited between February and June 2021. We observed that 1.8% of the CAD patients met all risk factor treatment targets. LDL-C had the lowest attainment level (5.1%), followed by BMI (59.7%), SBP (62.8%), antithrombotic usage (76.7%) and non-smoking status (94.4%). Apart from lower attainment of SBP control in the 50+ years age group (aOR: 0.57, 95% CI: 0.35-0.94) and women (aOR: 0.53, 95% CI: 0.34-0.83), the attainment levels of other risk factors were consistently low across age, sex, marital status and educational subgroups.

CONCLUSION

These findings emphasize the urgent need for effective management and heightened awareness, particularly for controlling LDL-C in the CAD population. Action to address this issue is crucial for mitigating the CVD burden, particularly in low- and middle-income countries such as Indonesia.

Korelasi antara Kadar Kalsium Serum dengan Fungsi Paru pada Penderita Penyakit Paru Obstruksi Kronik (PPOK)

Patologi PPOK menunjukkan gangguan inflamasi kronis yang dapat menyebabkan penyumbatan aliran udara di paru-paru, sedangkan kalsium diketahui memiliki kemampuan mengembalikan aspek respon bawaan. Kalsium juga memiliki peran dalam proses pergerakan otot pernapasan sebagai kompensasi untuk hambatan aliran udara. Penelitian ini bertujuan untuk mengetahui hubungan antara kadar kalsium serum dan fungsi paru pada pasien dengan PPOK. Penelitian ini menggunakan desain cross-sectional dengan analitik observasional, dilakukan selama 2 bulan, dengan total sampel 36 orang pasien PPOK. Berdasarkan hasil analisis data, diketahui bahwa tidak ada hubungan antara kadar kalsium serum dengan fungsi paru pada pasien PPOK (P> 0,05). Diperlukan penelitian lebih lanjut dengan sampel yang lebih besar dan penelitian dengan menggunakan variabel lebih spesifik seperti serum ion kalsium.

Cigarette Smoke Exposure and Stunting Among Under-five Children in Rural and Poor Families in Indonesia

Cigarette smoke exposure in mothers and children is highly prevalent in Asia, especially among rural and poor families. Second-hand smoke exposure might affect the nutritional status of children. Despite the emerging double burden of malnutrition and the very high prevalence of smoking in Indonesia, few studies have examined the effects of parental smoking on children's nutritional status. This study aims to measure the relationship between family smoking behavior and the occurrence of stunting in children under 5 years. This cross-sectional study used a purposive sampling technique, with 221 households with children aged 0 to 59 months from poor areas in Indonesia. Exposure to cigarette smoke is assessed using The Secondhand Smoke Exposure Scale questionnaire. The outcome measured is child stunting (height-for-age Z-score). The prevalence of stunting was estimated at 145 (65.6%). Children living with smoking parents were counted for 157 (71%), and most smoking exposure comes from fathers 147 (67.4%). The predictors of stunting in children under 5 years were a smoker father with (AOR 1.8; 95% CI 1.281-4.641), both parents are smokers increasing the risk of stunting with (COR 3.591; 95% CI 1.67-3.77), being exposed of smoke for more than 3 hours a day increase the risk of stunted children (COR 2.05; 95% CI 1.214-3.629), and using traditional cigarette or kretek expand the risk of stunting (AOR 3.19; 95% CI 1.139-67.785). The findings demonstrate the negative impact of parental smoking on children's growth, reinforcing the importance of reducing smoking prevalence by imposing a smoke-free home policy in the stunting prevention strategy.

Effect of remote ischemic postconditioning on left ventricular ejection fraction in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention

BACKGROUND

Ischemic conditioning may help patients with ST-segment elevation myocardial infarction (STEMI) to limit ventricular remodeling.

OBJECTIVES

To investigate the effect of remote ischemic postconditioning (RIPC) on left ventricular function during primary percutaneous coronary intervention (PPCI) in patients with STEMI.

MATERIAL AND METHODS

Pre- and post-test intervention study with a total of 60 STEMI patients. Patients were divided in two groups: with and without RIPC.

RESULTS

During the 6-month follow-up, a significant difference in left ventricular ejection fraction was observed in patients who underwent PPCI, which was higher in the group with RIPC in comparison with the group without RIPC: 1.0% (-1.0 to 4.3) vs. -1.0% (-4.0 to 1.3), p = 0.033. In addition, at 6-month measurement, left ventricular end-systolic volume in patients without RIPC was higher in comparison with their counterparts: 79.3 ± 30.5 mL vs. 64.4 ± 21.4 mL, p = 0.032.

CONCLUSIONS

RIPC shows favorable effects on left ventricular function and, therefore, in the future, it could be a potential cardioprotective strategy against ischemia-reperfusion injury in STEMI patients.

CYP2A6 gene polymorphism and severity of coronary atherosclerosis in Indonesian male smokers: A pilot study

Nicotine is a toxic alkaloid known to be responsible for the addictive feature of cigarettes. CYP2A6 genetic polymorphism among individuals was suspected to explain the relationship between cigarette smoking and related diseases. CYP2A6 works to slow nicotine metabolism and thus maintain a more prolonged nicotine concentration and increase nicotine exposure to the blood. We aimed to investigate the correlation between the CYP2A6 gene with the severity of coronary atherosclerosis. This cross-sectional study was conducted from April to July 2010 in Makassar Cardiac Centre, Dr Wahidin Sudirohusodo Hospital, Indonesia. Sixty-four male active smokers at the age of ≥45 years, diagnosed with coronary artery disease (CAD), were recruited and asked to smoke the usual number of cigarettes in the last 1 month prior to blood collection for CYP2A6 genotyping. Spearman correlation was performed to analyze the association between the allele variants and coronary stenosis degree, adjusted for CAD risk factors. Furthermore, we estimated the risk ratio to quantify the correlation. Of the 64 male smokers with CAD, the mean duration of smoking was 36.9 ± 8.6 years, and 49 (76.6%) were heavy smokers with >20 cigarettes per day. All 128 alleles were observed. Our results showed that all participants with CYP2A6 variants had a significant correlation with severe coronary artery stenosis (P = .006). Thus, this study suggests that the mutant CYP2A6 gene allele significantly increased the risk of having severe coronary stenosis 1.2 times higher compared to the wild type. This pilot study showed that CYP2A6 gene has an influential role in atherosclerotic development in male smokers. However, our findings should be confirmed with further more extensive studies.
