Blood pressure screening in Mata Sector, a rural area of Rwanda.

In rural sub-Saharan Africa, knowledge of non-communicable diseases such as high blood pressure (BP) is rather limited. This report provides information about a BP screening in Mata Sector, a rural region in Southern Province of Rwanda. Community-based, house-to-house screening was performed between February and July 2020 on more than 7000 inhabitants. The screening was conducted by a local team composed by 20 community health care workers, five community health care supervisors, and one nurse with hypertension surveillance training. BP and heart rate were recorded after 5 min of resting, using a validated automated oscillometric OMRON M6 IT-HEM-7322-E monitor with Intelli Wrap Cuff (HEM-FL31-E) technology. The mean of the second and third value was retained. BP was normal (<140/90 mm Hg) in 6340 (88%) and elevated in 863 (12%) participants with 95% of unawareness. Grade 1 (140-159/90-99 mm Hg) hypertensive BP readings were detected in 697 (81%), grade 2 (160-179/100-109 mm Hg) in 134 (16%), and grade 3 (≥180/≥110 mm Hg) in 32 (3.7%) individuals. The prevalence of hypertensive readings was significantly age-dependent. Additionally, a slightly greater proportion of participants with high BP (14% versus 11%) had a body mass index (BMI) ≥ 25.0 kg/m2. Also resting heart rate was higher in individuals with high BP (82 versus 77 beats/min). Although individuals identified with occasionally elevated BP values need further confirmatory measurements to establish the diagnosis of hypertension, these data suggest that high BP represents a noteworthy and preventable reason of concern within sub-Saharan Africa.

Single-Pill, Triple Antihypertensive Therapy in Rural Sub-Saharan Africa: Preliminary Experience.

INTRODUCTION: Worldwide, arterial hypertension is the foremost preventable and modifiable cardiovascular risk factor. In addition to lifestyle changes, recent international guidelines recommend single-pill, low-dose combinations as initial treatment strategy. We investigated whether this approach is feasible in a rural sub-Saharan Africa setting. METHODS: Diagnosis of hypertension was established over three sets of blood pressure measurements, performed according to the European Society of Hypertension recommendations by trained personnel, using a validated, automated, oscillometric device OMRON M7 IT-HEM-7322-E. In 98 individuals with arterial hypertension, a once-daily, single-pill combination of olmesartan, amlodipine, and hydrochlorothiazide was prescribed at an appropriate dose. Patients were instructed on its administration and potential side effects and encouraged towards lifestyle modifications. The treatment regimen was adjusted, if needed, at each outpatient clinic scheduled after 4, 8, 12, and 16 weeks. RESULTS: Seventy-nine patients (aged 61 [53-70] years; median and interquartile range) strictly adhered to the treatment schedule, while 19 individuals (70 [65-80] years) dropped out. Blood pressure was < 140/90 mmHg after 4 weeks in 44 (56%), after 8 weeks in 62 (78%), after 12 weeks in 69 (87%), and after 16 weeks in 74 (94%) participants. Excellent tolerance was reported. CONCLUSIONS: These results provide real-life evidence that hypertension management with a once-daily, single-pill combination of olmesartan, amlodipine, and hydrochlorothiazide as initial treatment is feasible and effective also in a rural sub-Saharan setting. Single-pill combinations should be made available also in rural and remote areas in low- and middle-income countries as a reliable first-line treatment strategy.

Tapentadol Immediate Release (IR) versus Morphine Hydrochloride for Postoperative Analgesia of Patients Undergoing Total Abdominal Hysterectomy-A Prospective Cohort Study.

Background and Objectives: This study aimed to examine the efficacy of tapentadol immediate release (IR) and morphine hydrochloride in the treatment of acute postoperative pain after total abdominal hysterectomy, as well as to examine the frequency of opioid-related side effects in observed patients. Materials and Methods: The prospective observational study was conducted over five months, and it included a total number of 100 patients. The two cohorts had different types of postoperative analgesia, and the effects were observed for 24 h postoperatively, by following the pain scores on NRS (Numerical Pain Scale), contentment with analgesia, and opioid-related side effects. Results: Statistical significance was found when assessing pain 24 h after surgery while coughing, where patients in the tapentadol IR group had significantly higher mean pain scores (p < 0.01). The subjective feeling of satisfaction with postoperative analgesia was statistically significant in the tapentadol IR group (p = 0.005). Vertigo appeared significantly more in patients from the morphine group (p = 0.03). Conclusions: Tapentadol IR (immediate release) and morphine hydrochloride are both effective analgesics used in the first 24 h after total transabdominal hysterectomy. Overall satisfaction of patients with analgesia was good. The frequency of side effects was higher in the morphine group, with statistical significance regarding the vertigo.

The Perioperative Pain Management Bundle is Feasible: Findings From the PAIN OUT Registry.

OBJECTIVES: The quality of postoperative pain management is often poor. A "bundle," a small set of evidence-based interventions, is associated with improved outcomes in different settings. We assessed whether staff caring for surgical patients could implement a "Perioperative Pain Management Bundle" and whether this would be associated with improved multidimensional pain-related patient-reported outcomes (PROs). METHODS: "PAIN OUT," a perioperative pain registry, offers tools for auditing pain-related PROs and obtaining information about perioperative pain management during the first 24 hours after surgery. Staff from 10 hospitals in Serbia used this methodology to collect data at baseline. They then implemented the "Perioperative Pain Management Bundle" into the clinical routine and collected another round of data. The bundle consists of 4 treatment elements: (1) a full daily dose of 1 to 2 nonopioid analgesics (eg, paracetamol and/or nonsteroidal anti-inflammatory drugs), (2) at least 1 type of local/regional anesthesia, (3) pain assessment by staff, and (4) offering patients information about pain management. The primary endpoint was a multidimensional pain composite score (PCS), evaluating pain intensity, interference, and side effects that was compared between patients who received the full bundle versus not. RESULTS: Implementation of the complete bundle was associated with a significant reduction in the PCS ( P < 0.001, small-medium effect size [ES]). When each treatment element was evaluated independently, nonopioid analgesics were associated with a higher PCS (ie, poorer outcome, and negligible ES), and the other elements were associated with a lower PCS (all negligible small ES). Individual PROs were consistently better in patients receiving the full bundle compared with 0 to 3 elements. The PCS was not associated with the surgical discipline. DISCUSSION: We report findings from using a bundle approach for perioperative pain management in patients undergoing mixed surgical procedures. Future work will seek strategies to improve the effect.

Convalescent plasma and all-cause mortality of COVID-19 patients: systematic review and meta-analysis.

Insight into the clinical potential of convalescent plasma in patients with coronavirus disease (COVID-19) is important given the severe clinical courses in unvaccinated and seronegative individuals. The aim of the study was to investigate whether there is a survival benefit of convalescent plasma therapy in COVID-19 patients. The authors independently assessed randomized controlled trials (RCTs) identified by the search strategy for inclusion, extracted data, and assessed risk of bias. The binary primary outcome was all-cause mortality. Risk ratio (RR) of the convalescent plasma treatment (vs. best standard care) and its associated standard error (effect size) were calculated. A random-effects model was employed to statistically pool the effect sizes of the selected studies. We included 19 RCTs with 17,021 patients. The random-effects model resulted in an estimated pooled RR of 0.94 (95% CI 0.81-1.08, p = 0.33), showing no statistical evidence of the benefit of convalescent plasma therapy on all-cause mortality. Convalescent plasma therapy was not found to be effective in reducing all-cause mortality in COVID-19 patients. Further studies are needed to determine in which patients convalescent plasma therapy may lead to a reduction in mortality.

Valor pronóstico de las frecuencias cardiacas bajas en pacientes ingresados con infarto agudo de miocardio / Prognostic value of low heart rates in patients admitted with acute myocardial infarction

Introducción y objetivos: Las escalas de predicción de riesgo utilizadas en síndromes coronarios agudos (SCA) utilizan modelos incrementales para estimar mortalidad para frecuencias cardiacas (FCs)> 60 lpm. Sin embargo, estudios previos comunicaron una relación no lineal entre la FC y los eventos, lo que sugiere que la FC baja puede tener un papel pronóstico no reconocido. El objetivo fue valorar el impacto pronóstico de las FCs baja en el SCA, definida como frecuencia cardiaca de admisión <50 lpm. Métodos: El estudio analizó datos del registro AMIS Plus, una cohorte de pacientes hospitalizados con SCA entre 1999 y 2021. El criterio de valoración principal fue la mortalidad hospitalaria por todas las causas, mientras que el compuesto de mortalidad por todas las causas se estableció por eventos cardiacos/cerebrovasculares mayores como secundario. Se adoptó una metodología estadística multinivel para evaluar el papel pronóstico de la FC baja en el SCA. Resultados: Se incluyó a 51.001 pacientes. La estimación cruda mostró una distribución bimodal de las variables resultados primaria y secundaria a FCs bajas y altas. Se observó una relación no lineal entre FCs y mortalidad intrahospitalaria mediante análisis restringido de spline cúbico. Una FC entre 50-75 mostró menor mortalidad que FC <50 lpm (OR=0,67; IC95%, 0,47-0,99) solo tras el análisis primario multivariado, no confirmado tras análisis múltiples de sensibilidad. Tras la puntuación de propensión emparejada, se hizo evidente el desvanecimiento progresivo del papel pronóstico de la FC <50 lpm. Conclusiones: Las FCs baja al ingreso en SCA se asocian a una mayor tasa cruda de eventos adversos. No obstante, tras la corrección de las diferencias basales, no se confirmó el papel pronóstico de la FC baja, sino que representa más bien un marcador de morbilidad subyacente. Estos resultados pueden ser clínicamente relevantes para mejorar la precisión de las puntuaciones de riesgo en el SCA.(AU)

Introduction and objectives: The risk prediction scores adopted in acute coronary syndromes (ACS) use incremental models to estimate mortality for heart rate (HR) above 60 bpm. Nonetheless, previous studies reported a nonlinear relationship between HR and events, suggesting that low HR may have an unrecognized prognostic role. We aimed to assess the prognostic impact of low HR in ACS, defined as admission HR <50 bpm. Methods: This study analyzed data from the AMIS Plus registry, a cohort of hospitalized patients with ACS between 1999 and 2021. The primary endpoint was in-hospital all-cause mortality, while a composite of all-cause mortality, major cardiac/cerebrovascular events was set as the secondary endpoint. A multilevel statistical method was used to assess the prognostic role of low HR in ACS. Results: The study included 51 001 patients. Crude estimates showed a bimodal distribution of primary and secondary endpoints with peaks at low and high HR. A nonlinear relationship between HR and in-hospital mortality was observed on restricted cubic spline analysis. An HR of 50 to 75 bpm showed lower mortality than HR <50 bpm (OR, 0.67; 95%CI, 0.47-0.99) only after primary multivariable analysis, which was not confirmed after multiple sensitivity analyses. After propensity score matching, progressive fading of the prognostic role of HR <50 bpm was evident. Conclusions: Low admission HR in ACS is associated with a higher crude rate of adverse events. Nonetheless, after correction for baseline differences, the prognostic role of low HR was not confirmed. Therefore, low HR probably represents a marker of underlying morbidity. These results may be clinically relevant in improving the accuracy of risk scores in ACS.(AU)

Patients With AMI and Severely Reduced LVEF, a Well-Defined, Still Extremely Vulnerable Population (Insights from AMIS Plus Registry).

Left ventricular ejection fraction (LVEF) represents one of the strongest predictors of both in-hospital and long-term prognosis in acute myocardial infarction (AMI). Temporal trends data coming from real-world experiences focused on patients with AMI with severely reduced LVEF (i.e., <30%) are lacking. In a total of 48,543 screened patients with AMI included in the Acute Myocardial Infarction in Switzerland Plus Registry between 2005 and 2020, data on LVEF were available for 23,510 patients. Study patients were classified according to LVEF as patients with AMI with or without severely reduced LVEF (i.e., patients with LVEF <30% and ≥30%, respectively). Overall, 1,657 patients with AMI (7%) displayed severely reduced LVEF. The prevalence of severe LVEF reduction constantly decreased over the study period (from 11% to 4%, p <0.001). In the subgroup of patients with severely reduced LVEF, a significant increase in revascularization rate was observed (from 61% to 84%, p <0.001); however, in-hospital mortality did not significantly decrease and remained well above 20% over the study period (from 23% to 26%, p = 0.65). At discharge, prescription of optimal cardioprotective therapy (defined as an association of renin-angiotensin-aldosterone-system inhibitors, ß-blocker, and mineral corticoid receptor antagonist) remained low across the study period (from 17% in 2011 to 20%, p = 0.96). In conclusion, patients with AMI with severely reduced LVEF remain a fragile subgroup of patients with an in-hospital mortality that did not significantly decrease and remained well above 20% over the study period. Moreover, access at discharge to optimal cardioprotective therapy remains suboptimal. Efforts are, therefore, needed to improve prognosis and access to guidelines-directed therapies in this fragile population.

Twenty-year trends in the prevalence of modifiable cardiovascular risk factors in young acute coronary syndrome patients hospitalized in Switzerland.

AIMS: Modifiable cardiovascular risk factors (RFs) play a key role in the development of coronary artery disease. We evaluated 20-year trends in RF prevalence among young adults hospitalized with acute coronary syndromes (ACS) in Switzerland. METHODS AND RESULTS: Data were analysed from the Acute Myocardial Infarction in Switzerland (AMIS) Plus registry from 2000 to 2019. Young patients were defined as those aged <50 years. Among 58 028 ACS admissions, 7073 (14.1%) were young (median 45.6 years, IQR 42.0-48.0), of which 91.6% had at least one modifiable RF and 59.0% had at least two RFs. Smoking was the most prevalent RF (71.4%), followed by dyslipidaemia (57.3%), hypertension (35.9%), obesity (21.7%), and diabetes (10.1%). Compared with older patients, young patients were more likely to be obese (21.7% vs. 17.4%, P < 0.001) and active smokers (71.4% vs. 33.9%, P < 0.001). Among young patients, between 2000 and 2019, there was a significant increase in the prevalence of hypertension from 29.0% to 51.3% and obesity from 21.2% to 27.1% (both Ptrend < 0.001) but a significant decrease in active smoking from 72.5% to 62.5% (Ptrend = 0.02). There were no significant changes in the prevalence of diabetes (Ptrend = 0.32) or dyslipidaemia (Ptrend = 0.067). CONCLUSION: Young ACS patients in Switzerland exhibit a high prevalence of RFs and are more likely than older patients to be obese and smokers. Between 2000 and 2019, RF prevalence either increased or remained stable, except for smoking which decreased but still affected approximately two-thirds of young patients in 2019. Public health initiatives targeting RFs in young adults in Switzerland are warranted.

We evaluated the prevalence of risk factors (RFs) among young patients admitted with ACS in Switzerland between 2000 and 2019. Young ACS patients in Switzerland exhibited a high prevalence of RFs. There was a significant increase in the prevalence of hypertension and obesity. Despite a significant decrease, active smoking remained the most prevalent RF. These findings strongly suggest that public health initiatives targeting RFs in young adults in Switzerland are warranted.

Prognostic value of low heart rates in patients admitted with acute myocardial infarction.

INTRODUCTION AND OBJECTIVES: The risk prediction scores adopted in acute coronary syndromes (ACS) use incremental models to estimate mortality for heart rate (HR) above 60 bpm. Nonetheless, previous studies reported a nonlinear relationship between HR and events, suggesting that low HR may have an unrecognized prognostic role. We aimed to assess the prognostic impact of low HR in ACS, defined as admission HR <50 bpm. METHODS: This study analyzed data from the AMIS Plus registry, a cohort of hospitalized patients with ACS between 1999 and 2021. The primary endpoint was in-hospital all-cause mortality, while a composite of all-cause mortality, major cardiac/cerebrovascular events was set as the secondary endpoint. A multilevel statistical method was used to assess the prognostic role of low HR in ACS. RESULTS: The study included 51 001 patients. Crude estimates showed a bimodal distribution of primary and secondary endpoints with peaks at low and high HR. A nonlinear relationship between HR and in-hospital mortality was observed on restricted cubic spline analysis. An HR of 50 to 75 bpm showed lower mortality than HR <50 bpm (OR, 0.67; 95%CI, 0.47-0.99) only after primary multivariable analysis, which was not confirmed after multiple sensitivity analyses. After propensity score matching, progressive fading of the prognostic role of HR <50 bpm was evident. CONCLUSIONS: Low admission HR in ACS is associated with a higher crude rate of adverse events. Nonetheless, after correction for baseline differences, the prognostic role of low HR was not confirmed. Therefore, low HR probably represents a marker of underlying morbidity. These results may be clinically relevant in improving the accuracy of risk scores in ACS.

Reducing gap in pre-hospital delay between women and men presenting with ST-elevation myocardial infarction.

AIMS: This study aimed to analyse changes in pre-hospital delay over time in women and men presenting with ST-elevation myocardial infarction (STEMI) in Switzerland. METHODS AND RESULTS: AMIS Plus registry data of patients admitted for STEMI between 2002 and 2019 were analysed using multivariable quantile regression including the following covariates: interaction between sex and admission year, age, diabetes, pain at presentation, myocardial infarction (MI) history, heart failure history, hypertension, and renal disease. Among the 15,350 patients included (74.5% men), the median (interquartile range) delay between 2002 and 2019 was 150 (84; 345) min for men and 180 (100; 414) min for women. The unadjusted median pre-hospital delay significantly decreased over time for both sexes but the decreasing trend was stronger for women. Specifically, the unadjusted sex differences in delay decreased from 60 min in 2002 (P = 0.0042) to 40.5 min in 2019 (P = 0.165). The multivariable model revealed a significant interaction between sex and admission year (P = 0.038) indicating that the decrease in delay was stronger for women (-3.3 min per year) than for men (-1.6 min per year) even after adjustment. The adjusted difference between men and women decreased from 26.93 min in 2002 to -1.97 min for women in 2019. CONCLUSION: Over two decades, delay between symptom onset and hospital admission in STEMI decreased significantly for men and women. The decline was more pronounced in women, leading to the sex gap disappearing in the adjusted analysis for 2019.

Because the delay between onset of heart attack symptoms and hospital admission was higher in women in the past, this study analysed whether pre-hospital delay has shortened in general since 2002 as well as in women and men separately.Our study showed that the pre-hospital delay steadily decreased for both sexes but the decrease was greater in womenAfter considering differences in patient characteristics, such as higher age and less previous heart attacks in women, by 2019 the delay was nearly the same for women and men.

Impact of Cardiovascular Risk Factors on Arterial Stiffness in a Countryside Area of Switzerland: Insights from the Swiss Longitudinal Cohort Study.

INTRODUCTION: Cardiovascular disease is the leading cause of morbidity and mortality. Besides traditional cardiovascular risk factors, arterial stiffness is a recognized predictor of cardiovascular risk. METHODS: We investigated the relationship between traditional cardiovascular risk factors, sex, and aortic pulse wave velocity in subjects living in a countryside area of Southern Switzerland. For this aim, we performed a cross-sectional analysis of data from adult participants of the Swiss Longitudinal Cohort Study, which, initiated in 2015, follows health status and disease risk factors in a Swiss countryside cohort at least 6 years of age. RESULTS: A total of 387 people (205 women and 182 men) were included. Hyperlipidemia, overweight, and obesity were more common (p ≤ 0.001) and LDL-cholesterol, triglycerides, and hemoglobin A1c were higher (p < 0.03) in men than women. Systolic and diastolic brachial and aortic blood pressures were higher in men (p < 0.02), whereas aortic pulse wave velocity and aortic pulse pressure were higher in women (p < 0.05). The aortic pulse wave velocity was significantly higher in subjects with hypertension, hyperlipidemia, diabetes, and obesity, and significantly increased with age (p < 0.0001). Multiple linear regression analysis showed a significant correlation between pulse wave velocity and age, female sex, brachial systolic blood pressure, and heart rate (p < 0.005). CONCLUSION: Also in a countryside area, the aortic pulse wave velocity is higher in subjects with hypertension, hyperlipidemia, diabetes and obesity, and significantly increases with age. Furthermore, with advancing age, aortic pulse wave velocity is higher in women than men. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT02282748.

Sex-specific evaluation and redevelopment of the GRACE score in non-ST-segment elevation acute coronary syndromes in populations from the UK and Switzerland: a multinational analysis with external cohort validation.

BACKGROUND: The Global Registry of Acute Coronary Events (GRACE) 2.0 score was developed and validated in predominantly male patient populations. We aimed to assess its sex-specific performance in non-ST-segment elevation acute coronary syndromes (NSTE-ACS) and to develop an improved score (GRACE 3.0) that accounts for sex differences in disease characteristics. METHODS: We evaluated the GRACE 2.0 score in 420 781 consecutive patients with NSTE-ACS in contemporary nationwide cohorts from the UK and Switzerland. Machine learning models to predict in-hospital mortality were informed by the GRACE variables and developed in sex-disaggregated data from 386 591 patients from England, Wales, and Northern Ireland (split into a training cohort of 309 083 [80·0%] patients and a validation cohort of 77 508 [20·0%] patients). External validation of the GRACE 3.0 score was done in 20 727 patients from Switzerland. FINDINGS: Between Jan 1, 2005, and Aug 27, 2020, 400 054 patients with NSTE-ACS in the UK and 20 727 patients with NSTE-ACS in Switzerland were included in the study. Discrimination of in-hospital death by the GRACE 2.0 score was good in male patients (area under the receiver operating characteristic curve [AUC] 0·86, 95% CI 0·86-0·86) and notably lower in female patients (0·82, 95% CI 0·81-0·82; p<0·0001). The GRACE 2.0 score underestimated in-hospital mortality risk in female patients, favouring their incorrect stratification to the low-to-intermediate risk group, for which the score does not indicate early invasive treatment. Accounting for sex differences, GRACE 3.0 showed superior discrimination and good calibration with an AUC of 0·91 (95% CI 0·89-0·92) in male patients and 0·87 (95% CI 0·84-0·89) in female patients in an external cohort validation. GRACE 3·0 led to a clinically relevant reclassification of female patients to the high-risk group. INTERPRETATION: The GRACE 2.0 score has limited discriminatory performance and underestimates in-hospital mortality in female patients with NSTE-ACS. The GRACE 3.0 score performs better in men and women and reduces sex inequalities in risk stratification.

Occupational radiation dose of personnel involved in sentinel node biopsy procedure.

INTRODUCTION: Sentinel node biopsy is a procedure used for axillary nodal staging in breast cancer surgery. The process uses radioactive 99mTc isotope for mapping the sentinel node(s) and all the staff involved in the procedure is potentially exposed to ionizing radiation. The colloid for radiolabelling (antimone-sulphide) with 99mTc isotope (half-life 6 h) is injected into the patient breast. The injection has activity of 18.5 MBq. The surgeon removes the primary tumor and detects active lymph nodes with gamma detection unit. The tumor as well as the active nodal tissue is transferred to pathologist for the definitive findings. The aim of the study was to measure dose equivalents to extremities and whole body for all staff and suggest practice improvement in order to minimize exposure risk. MATERIALS AND METHODS: The measurements of the following operational quantities were performed: Hp(10) personal dose equivalent to whole body and Hp(0.07) to extremities for staff as well as ambiental dose for operating theatre and during injection. Hp(0.07) were measured at surgeon's finger by ring thermoluminescent dosimeter (TLD) type MTS-N, and reader RADOS RE2000. Surgeon and nurse were wearing TLD personal dosimeter at the chest level. Anesthesiologist and anesthetist were wearing electronic personal dosimeters, while pathologist was wearing ring TLD while manipulating tissue samples. Electronic dosimeters used were manufactured by Polimaster, type PM1610. All TLD and electronic dosimeters data were reported, including background radiation. Background radiation was also monitored separately. Personal TLDs are standard for this type of personal monitoring, provided by accredited laboratory. Measurements of ambiental dose in workplaces of other staff involved around the patient was performed before the surgery took place, by calibrated survey meters manufactured by Atomtex, type 1667. The study involved two surgeons and one pathologist, two anesthesiologists and three anesthetists during two months period. RESULTS AND DISCUSSION: The doses received by all staff are evaluated using passive and active personal dosimeters and ambiental dose monitors and practice was improved based on results collected. Average annual whole body dose for all staff involved in the procedure was less than 0.8 mSv. Extremity dose equivalents to surgeon and pathologist were far below the limits set for professionally exposed (surgeon) and for public (pathologist). CONCLUSIONS: Although has proven to be very safe for all staff, additional measures for radiation protection, in accordance to ALARA principle (As Low As Reasonably Achievable) should be conducted. The recommendations for practice improvement with respect to radiation protection were issued.

Prevalence of ideal cardiovascular health in a community-based population - results from the Swiss Longitudinal Cohort Study (SWICOS).

AIMS OF THE STUDY: The American Heart Association (AHA) developed a concept to measure cardiovascular health in populations. We aimed to analyse participants in the Swiss Longitudinal Cohort Study (SWICOS) according to the AHA concept. METHODS: We analysed cardiovascular health according to the AHA concept in all 474 participants of the prospective, population-based SWICOS study who were 18 years or older. The AHA concept uses seven health metrics of known cardiovascular risk factors (blood pressure, total cholesterol, blood glucose, smoking, body weight, physical activity and diet), and classifies each health metric according to three levels (ideal, intermediate and poor) using pre-defined cut-offs. RESULTS: Ideal cardiovascular health for three or more of the seven health metrics was found in 259 participants (54.9%; 95% confidence interval [CI] 50.1-59.4%), but a relevant number of participants (n = 213, 45.1%, 95% CI 40.6-49.7%) showed ideal cardiovascular health for only two or fewer of the seven health metrics. Poor cardiovascular health for three or more of the seven health metrics was found in 40 participants (8.5%; 95% CI 6.1-11.4%); a majority of 432 participants (91.5%; 95% CI 88.6-93.9%) showed a poor level for only two or fewer of the seven health metrics. CONCLUSIONS: Overall, we found favourable results for cardiovascular health in the population-based SWICOS cohort. Nevertheless, we see the need for further health prevention campaigns given the fact that a relevant proportion of the participants could optimise their cardiovascular health.

Dual antiplatelet therapy is under-prescribed in patients with surgically treated acute myocardial infarction.

OBJECTIVES: Despite guideline recommendations, previous reports, coming mainly from outside Europe, showed low rates of prescriptions for dual antiplatelet therapy (DAPT) in patients with acute myocardial infarction (AMI) undergoing surgical revascularization. The present study assesses this issue in the era of potent P2Y12 inhibitors in Switzerland. METHODS: All patients with a diagnosis of AMI included in the Acute Myocardial Infarction in Switzerland Plus Registry from January 2014 to December 2019 were screened; 9050 patients undergoing either percutaneous (8727, 96.5%) or surgical (323, 3.5%) revascularization were included in the analysis. RESULTS: Surgically treated patients were significantly less likely to receive DAPT at discharge (56.3% vs 96.7%; P < 0.001). Even when discharged with a prescription for DAPT, those patients were significantly less likely to receive a regimen containing a new P2Y12 inhibitor (67/182 [36.8%] vs 6945/8440 [83.2%]; P < 0.001). At multivariate analysis, surgical revascularization was independently associated with a lower likelihood of receiving a prescription for DAPT at discharge (odds ratio 0.03, 95% confidence interval 0.02-0.06). CONCLUSIONS: DAPT prescriptions for patients with AMI undergoing surgical revascularization are not in line with current guideline recommendations. Efforts are necessary to clarify the role of DAPT for secondary prevention in these patients and increase the confidence of treating physicians in guideline recommendations.

Age-Dependency of Cardiometabolic Risk and Protective Factors in Females Living in a Countryside Area of Switzerland.

We investigated the effect of age on cardiometabolic risk and protective factors in females living in a countryside area of Switzerland. For this cross-sectional analysis, data from 268 female adults, who live in two neighboring countryside villages in Italian-speaking Switzerland were retained. 89 study participants were premenopausal, 82 climacteric and 97 postmenopausal. Television viewing time, short duration of sleep, overweight, blood pressure, levels of atherogenic lipids and glycated hemoglobin significantly increased with age. Walking time also significantly increased with age. Tobacco smoking was more common among premenopausal women. It is concluded that in these countryside villages climacteric and postmenopausal women generally have an unfavorable cardiometabolic risk profile. On the other side, low physical activity and smoking are, compared to premenopausal and climacteric women, less prevalent in postmenopausal women.

Comparison of P2Y12 receptor inhibitors in patients with ST-elevation myocardial infarction in clinical practice: a propensity score analysis of five contemporary European registries.

AIMS: Among acute coronary syndromes (ACS), ST-segment elevation myocardial infarction (STEMI) has the most severe early clinical course. Recent randomized clinical trials have demonstrated that novel antithrombotic therapies improve in-hospital outcomes in STEMI patients. We aimed to describe the effectiveness and safety of P2Y12 receptor inhibitors in clinical practice in patients with STEMI based on data from contemporary European ACS registries. METHODS AND RESULTS: Five registries from the PIRAEUS initiative (AAPCI/ADPAT, ALKK-PIC, AMIS Plus, Belgium STEMI, and EYESHOT) provided data for the assessment of P2Y12 receptor inhibitor-based dual antiplatelet therapy. Registries were heterogeneous in terms of setting, patient characteristics, and treatment selection. Matched pair analysis and propensity score matching were used to assess all-cause in-hospital death rates based on data from 25 250 patients (8577 patients on prasugrel, 5995 on ticagrelor, and 10 678 on clopidogrel). The odds ratio (OR) for the death of any cause when compared with clopidogrel was 0.72 [95% confidence interval (CI) 0.62-0.84, P < 0.001] in favour of the new P2Y12 receptor inhibitors (prasugrel and ticagrelor combined). In the comparison between prasugrel and ticagrelor, there were no relevant differences (OR 0.97, 95% CI 0.77-1.23; P = 0.81). Event rates of cardiovascular death and stroke were also substantially lower for the new P2Y12 receptor inhibitors. The differences between clopidogrel and prasugrel or ticagrelor on major bleeding were numerically in the same order as for death of any cause but were not statistically significant. No differences in ischaemic and bleeding outcomes were observed between prasugrel and ticagrelor. CONCLUSION: This analysis suggests that the prasugrel or ticagrelor compared with clopidogrel have favourable outcomes in clinical practice while not being inferior in terms of safety.

Temporal trends in cardiovascular risk factors' prevalence in patients with myocardial infarction.

INTRODUCTION AND OBJECTIVES: Little is known about changes in cardiovascular risk factors (CVRF) profile over time in patients presenting with acute myocardial infarction (AMI). METHODS: We assessed changes in age and CVRF profile in consecutive AMI patients enrolled in the Swiss nationwide AMIS Plus registry between 1 January 1997 and 31 December 2018. RESULTS: A total of 57 995 AMI patients were included in the analysis. Mean age at presentation was 71.5 ± 11.3 years for women and 63.9 ± 12.8 years for men and did not change over time. Overall, the mean (standard deviation) number of CVRF increased from 1.76 (1.07) in 1997/98 to 2.26 (1.10) in 2017/18 in men (Ptrend  < .001), while the corresponding rates in females were 1.83 (1.11) and 2.24 (1.08) (Ptrend  < .001). In terms of active smoking, no significant trend was detected for males, while there was a significant increase in females (P < .001). As a result, the gap in smoking rates between men and women presenting with AMI decreased from 19.9% (45.3% vs 25.4%) in 1997/98 to 7.9% (41.2% vs 33.3%) in 2017/18. Reassuring was the stability in terms of diabetes prevalence for both genders. Obesity was more prevalent over time in men, while the prevalence of hypertension and dyslipidemia increased in both genders. CONCLUSION: Among patients with AMI in Switzerland over two decades, age at presentation remained stable, while the mean number of CVRF increased in both men and women. Striking was the increase in the prevalence of smoking in women, leading to a reduction of the gender gap over time.

Going beyond the mean: economic benefits of myocardial infarction secondary prevention.

BACKGROUND: Using the example of secondary prophylaxis of myocardial infarction (MI), our aim was to establish a framework for assessing cost consequences of compliance with clinical guidelines; thereby taking cost trajectories and cost distributions into account. METHODS: Swiss mandatory health insurance claims from 1840 persons with hospitalization for MI in 2014 were analysed. Included persons were predominantly male (74%), had a median age of 73 years, and 71% were pre-exposed to drugs for secondary prophylaxis, prior to index hospitalization. Guideline compliance was defined as being prescribed recommended 4-class drug prophylaxis including drugs from the following four classes: beta-blockers, statins, aspirin or P2Y12 inhibitors, and angiotension-converting enzyme inhibitors or angiotensin receptor blockers. Health care expenditures (HCE) accrued over 1 year after index hospitalization were compared by compliance status using two-part regression, trajectory analysis, and counterfactual decomposition analysis. RESULTS: Only 32% of persons received recommended 4-class prophylaxis. Compliant persons had lower HCE (- 4865 Swiss Francs [95% confidence interval - 8027; - 1703]) and were more likely to belong to the most favorable HCE trajectory (with 6245 Swiss Francs average annual HCE and comprising 78% of all studied persons). Distributional analyses showed that compliance-associated HCE reductions were more pronounced among persons with HCE above the median. CONCLUSIONS: Compliance with recommended prophylaxis was robustly associated with lower HCE and more favorable cost trajectories, but mainly among persons with high health care expenditures. The analysis framework is easily transferrable to other diseases and provides more comprehensive information on HCE consequences of non-compliance than mean-based regressions alone.
