RESUMEN

AIMS: We evaluated the incidence and relative risk of major post-acute cardiovascular consequences of SARS-CoV-2 infection in a large real-world population from a primary care database in a region at moderate cardiovascular risk followed up in the period 2020-22. METHODS AND RESULTS: This is a retrospective cohort analysis using data from a cooperative of general practitioners in Italy. Individuals aged >18 affected by COVID-19 starting from January 2020 have been followed up for 3 years. Anonymized data from 228 266 patients in the period 2020-22 were considered for statistical analysis and included 31 764 subjects with a diagnosis of COVID-19. An equal group of subjects recorded in the same database in the period 2017-19 was used as propensity score-matched comparison as an unquestionable COVID-19-free population. Out of the 228 266 individuals included in the COMEGEN database during 2020-22, 31 764 (13.9%) were ascertained positive with SARS-CoV-2 infection by a molecular test reported to general practitioners. The proportion of individuals with a new diagnosis of major adverse cardiovascular and cerebrovascular events was higher in the 2020-22 COVID-19 group than in the 2017-19 COMEGEN propensity score-matched comparator, with an odds ratio of 1.73 (95% confidence interval: 1.53-1.94; P < 0.001). All major adverse cardiovascular and cerebrovascular events considered showed a significantly higher risk in COVID-19 individuals. Incidence calculated for each 6-month period after the diagnosis of COVID-19 in our population was the highest in the first year (1.39% and 1.45%, respectively), although it remained significantly higher than in the COVID-19-free patients throughout the 3 years. CONCLUSION: The increase of cardiovascular risk associated with COVID-19 might be extended for years and not limited to the acute phase of the infection. This should promote the planning of longer follow-up for COVID-19 patients to prevent and promptly manage the potential occurrence of major adverse cardiovascular and cerebrovascular events.

RESUMEN

BACKGROUND: While the augmented incidence of diabetes after COVID-19 has been widely confirmed, controversial results are available on the risk of developing hypertension during the COVID-19 pandemic. METHODS: We designed a longitudinal cohort study to analyze a closed cohort followed up over a 7-year period, i.e., 3 years before and 3 years during the COVID-19 pandemic, and during 2023, when the pandemic was declared to be over. We analyzed medical records of more than 200,000 adults obtained from a cooperative of primary physicians from January 1, 2017, to December 31, 2023. The main outcome was the new diagnosis of hypertension. RESULTS: We evaluated 202,163 individuals in the pre-pandemic years and 190,743 in the pandemic years, totaling 206,857 when including 2023 data. The incidence rate of new hypertension was 2.11 (95% C.I. 2.08-2.15) per 100 person-years in the years 2017-2019, increasing to 5.20 (95% C.I. 5.14-5.26) in the period 2020-2022 (RR = 2.46), and to 6.76 (95% C.I. 6.64-6.88) in 2023. The marked difference in trends between the first and the two successive observation periods was substantiated by the fitted regression lines of two Poisson models conducted on the monthly log-incidence of hypertension. CONCLUSIONS: We detected a significant increase in new-onset hypertension during the COVID-19 pandemic, which at the end of the observation period affected ~ 20% of the studied cohort, a percentage higher than the diagnosis of COVID-19 infection within the same time frame. This observation suggests that increased attention to hypertension screening should not be limited to individuals who are aware of having contracted the infection but should be extended to the entire population.

RESUMEN

Emerging evidence indicates that the relationship between coronavirus disease 2019 (COVID-19) and diabetes is 2-fold: 1) it is known that the presence of diabetes and other metabolic alterations poses a considerably high risk to develop a severe COVID-19; 2) patients who survived a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have an increased risk of developing new-onset diabetes. However, the mechanisms underlying this association are mostly unknown, and there are no reliable biomarkers to predict the development of new-onset diabetes. In the present study, we demonstrate that a specific microRNA (miR-34a) contained in circulating extracellular vesicles released by endothelial cells reliably predicts the risk of developing new-onset diabetes in COVID-19. This association was independent of age, sex, body mass index (BMI), hypertension, dyslipidemia, smoking status, and D-dimer. SIGNIFICANCE STATEMENT: We demonstrate for the first time that a specific microRNA (miR-34a) contained in circulating extracellular vesicles released by endothelial cells is able to reliably predict the risk of developing diabetes after having contracted coronavirus disease 2019 (COVID-19). This association was independent of age, sex, body mass index (BMI), hypertension, dyslipidemia, smoking status, and D-dimer. Our findings are also relevant when considering the emerging importance of post-acute sequelae of COVID-19, with systemic manifestations observed even months after viral negativization (long COVID).

RESUMEN

Recent studies have yielded controversial results on the long-term effects of statins on the risk of cardiovascular (CV) events. To fill this knowledge gap, we assessed the relationship between low-density lipoprotein cholesterol (LDL-C) levels and CV events in hypertensive patients without previous CV events and naïve to antidyslipidemic treatment within the "Campania Salute Network" in Southern Italy. We studied 725 hypertensive patients with a mean follow-up of 85.4 ± 25.7 months. We stratified our cohort into three groups based on LDL cholesterol (LDL-C) levels in mg/dl: group 1) patients showing during the follow-up a mean LDL-C value ≤100 mg/dl in absence of statin therapy; group 2) statin-treated patients with LDL ≤100 mg/dl; and group 3) patients with LDL-C >100 mg/dl. No significant difference among the groups was observed in terms of demographic and clinical characteristics and medications. The incidence of first CV events was 5.7% in group 1, 6.0% in group 2, and 11.9% in group 3 (P < 0.05 vs. group 1 and group 2). A stable long-term satisfactory control of LDL-C plasma concentration (≤100 mg/dl) reduced the incidence of major CV events from one event every 58.6 patients per year to one event every 115.9 patients per year. These findings were confirmed in a Cox regression analysis, adjusting for potential confounding factors. Collectively, our data demonstrate that a 7-year stable control of LDL-C reduces the incidence of CV events by 40%. SIGNIFICANCE STATEMENT: There are several discrepancies between Mendelian studies and other investigations concerning the actual effects of reduction of plasma concentration of low-density lipoprotein (LDL) cholesterol on the incidence of major cardiovascular events. Taken together, our data in nondiabetic subjects show that a 7-year stable control of LDL cholesterol induces a ∼40% reduction of the incidence of cardiovascular events.

RESUMEN

Background: Recent reports have evidenced an increased mortality rate in hypertensive patients with electrocardiographic left ventricular hypertrophy (ECG-LVH) achieving systolic blood pressure (SBP) <130mmHg. However, to the best of our knowledge, the actual effects of BP reduction to the {less than or equal to}130/80mmHg target on the incidence of cardiovascular events in hypertensive patients with a diagnosis of LVH based on echocardiographic-criteria (Echo-LVH) have never been determined. Methods: In order to fill this long-standing knowledge gap, we harnessed a population of 9511 hypertensive patients, followed-up for 33.6 [IQR 7.9-72.7] months. The population was divided into six groups according to the average SBP achieved during the follow-up ({less than or equal to}130, 130-to-139, and {greater than or equal to}140mmHg) and absence/presence of Echo-LVH. The primary endpoint was a composite of fatal or non-fatal myocardial infarction and stroke, sudden cardiac death, heart failure requiring hospitalization, revascularization, and carotid stenting. Secondary endpoints included atrial fibrillation and transient ischemic attack. Results: During the follow-up, achieved SBP and diastolic BP (DBP) were comparable between patients with and without Echo-LVH. Strikingly, the rate of primary and secondary endpoints was significantly higher in patients with Echo-LVH and SBP>130mmHg, reaching the highest rate in the Echo-LVH group with SBP{greater than or equal to}140mmHg. By separate Cox multivariable regressions, after adjusting for potential confounders, both primary and secondary endpoints were significantly associated with SBP{greater than or equal to}140mmHg and Echo-LVH. Instead, DBP reduction {less than or equal to}80mmHg was associated with a significant increased rate of secondary events. Conclusions: In hypertensive patients with Echo-LVH, achieving an average in-treatment SBP target {less than or equal to}130mmHg has a beneficial prognostic impact on incidence of cardiovascular events. Significance Statement In contrast with recent reports, achieving in-treatment SBP≤130mmHg reduces the incidence of CV events in hypertensive patients with Echo-LVH. Reducing DBP≤80mmHg is instead associated with a higher rate of CV complications. By Cox multivariable regression models, adjusting for potential confounders, the rate of hard and soft CV events was significantly associated with Echo-LVH and SBP≥140mmHg. Our data indicate that therapeutic strategies in patients with Echo-LVH should aim at reducing SBP≤130mmHg paying attention to not reducing DBP≤80mmHg.

RESUMEN

Background: The association of COVID-19 with the development of new-onset diabetes has been recently investigated by several groups, yielding controversial results. Population studies currently available in the literature are mostly focused on type 1 diabetes (T1D), comparing patients with a SARS-CoV-2 positive test to individuals without COVID-19, especially in paediatric populations. In this study, we sought to determine the incidence of type 2 diabetes (T2D) before and during the COVID-19 pandemic. Methods: In this longitudinal cohort study, we analysed a cohort followed up over a 6-year period using an Interrupted Time Series approach, i.e. 3-years before and 3-years during the COVID-19 pandemic. We analysed data obtained from >200,000 adults in Naples (Italy) from January 1st 2017 to December 31st 2022. In this manner, we had the opportunity to compare the incidence of newly diagnosed T2D before (2017-2019) and during (2020-2022) the COVID-19 pandemic. The key inclusion criteria were age >18-year-old and data availability for the period of observation; patients with a diagnosis of diabetes obtained before 2017 were excluded. The main outcome of the study was the new diagnosis of T2D, as defined by the International Classification of Diseases 10 (ICD-X), including prescription of antidiabetic therapies for more than 30 days. Findings: A total of 234,956 subjects were followed-up for at least 3-years before or 3-years during the COVID-19 pandemic and were included in the study; among these, 216,498 were analysed in the pre-pandemic years and 216,422 in the pandemic years. The incidence rate of T2D was 4.85 (95% CI, 4.68-5.02) per 1000 person-years in the period 2017-2019, vs 12.21 (95% CI, 11.94-12.48) per 1000 person-years in 2020-2022, with an increase of about twice and a half. Moreover, the doubling time of the number of new diagnoses of T2D estimated by unadjusted Poisson model was 97.12 (95% CI, 40.51-153.75) months in the prepandemic period vs 23.13 (95% CI, 16.02-41.59) months during the COVID-19 pandemic. Interestingly, these findings were also confirmed when examining patients with prediabetes. Interpretation: Our data from this 6-year study on more than 200,000 adult participants indicate that the incidence of T2D was significantly higher during the pandemic compared to the pre-COVID-19 phase. As a consequence, the epidemiology of the disease may change in terms of rates of outcomes as well as public health costs. COVID-19 survivors, especially patients with prediabetes, may require specific clinical programs to prevent T2D.

RESUMEN

Aims: Chronic pressure overload determines functional and structural alterations, leading to hypertension-mediated organ damage (HMOD), affecting multiple districts. We aim at evaluating the prognostic impact of the absence vs. presence of HMOD in one or more sites and of blood pressure (BP) and metabolic control in hypertensive patients. Methods and results: The study included 7237 hypertensive patients from the Campania Salute Network Registry, followed up for 5.3 ± 4.5 years. As HMOD, we analysed the presence of left ventricular hypertrophy, carotid plaques, and chronic kidney disease (CKD-EPI ≥3 stage) and evaluated the impact of zero vs. one vs. two vs. three sites of HMOD on the occurrence of major adverse cardiovascular events (MACEs). Blood pressure control and Metabolic Score for Insulin Resistance (METS-IR) were also considered. Optimal BP control was achieved in 57.3% patients. Major adverse cardiovascular events occurred in 351 (4.8%) patients. The MACE rate in patients without HMOD was 2.7%, whereas it was 4.7, 7.9, and 9.8% in patients with one, two, and three sites with HMOD, respectively. By using Cox multivariate models, adjusted for age, BP control, mean heart rate, mean METS-IR, number of HMOD sites, and drugs, MACE was found to be significantly associated with ageing, mean METS-IR, anti-platelet therapy, and multiple sites with HMOD, whereas a negative association was found with renin-angiotensin system inhibitor drugs. Conclusion: In hypertensive patients, the risk of MACE increases with the incremental number of districts involved by HMOD, independent of BP control and despite the significant impact of metabolic dysregulation. Hypertension-mediated organ damage involving multiple sites is the deleterious consequence of hypertension and dysmetabolism but, when established, it represents an independent cardiovascular risk factor for MACE occurrence.

RESUMEN

AIMS: In the present study, we assessed correlates and their consistency of ascending aorta (AscAo) measurement in treated hypertensive patients. METHODS AND RESULTS: A total of 1634 patients ≥ 18 years old with available AscAo ultrasound were included. Ascending aorta was measured at end-diastole with leading edge to leading edge method, perpendicular to the long axis of the aorta in parasternal long-axis view at its maximal identifiable dimension. Correlations of AscAo and AscAo normalized for height (AscAo/HT) or body surface area (AscAo/BSA) with demographics and metabolic profile were explored. Multi-variable regression was also used to identify potential confounders influencing univariate correlations. Sensitivity analysis was performed using cardiovascular (CV) outcome. Correlations with age, estimated glomerular filtration rate, systolic blood pressure (BP), and heart rate (HR) were similar among the three aortic measures. Women exhibited smaller AscAo but larger AscAo/BSA than men with AscAo/HT offsetting the sex difference. Obesity and diabetes were associated with greater AscAo and AscAo/HT but with smaller AscAo/BSA (all P < 0.001). In multi-variable regression model, all aortic measure confirmed the sign of their relations with sex and metabolic profile independently of age, BP, and HR. In Kaplan-Mayer analysis, only dilated AscAo and AscAo/HT were significantly associated with increased risk of CV events (both P < 0.008). CONCLUSIONS: Among patients with long-standing controlled systemic hypertension, magnitude of aortic remodelling is influenced by the type of the measure adopted, with physiological consistency only for AscAo and AscAo/HT, but not for AscAo/BSA.


Long-standing hypertension leads to the development of aortic remodelling. In particular, the haemodynamic overload due to high blood pressure may contribute to the development of ascending aorta (AscAo) dilatation. With present study we analysed, in treated hypertensive patients, the spectrum of AscAo dilatation using different anthropometric criteria reporting the clinical and echocardiographic correlates: Indexing AscAo for body surface area (BSA) leads to inconsistent negative association with obesity and other metabolic abnormalities while AscAo and AscAo indexed for height present consistent pathophysiologic profile.In sensitivity analysis, AscAo and AscAo indexed for height are significantly associated with incident cardiovascular events while indexation for BSA is not, strongly suggesting the use of AscAo/BSA should be discouraged.

RESUMEN

BACKGROUND: Arterial hypertension causes cardiac functional and structural alterations. In hypertensive patients without flow-limiting epicardial coronary artery disease, we investigated possible relationships between positron emission tomography/computed tomography-derived myocardial blood flow (MBF) and echocardiographic parameters of left ventricular (LV) performance, including mechano-energetic efficiency indexed for myocardial mass (MEEi). METHODS: Seventy-eight hypertensive patients without flow-limiting epicardial coronary artery disease underwent echocardiography, including MEEi computation, and cardiac positron emission tomography/computed tomography with assessment of MBF/mass ratio at rest and after stress and myocardial flow reserve. The lowest MEEi tertile (MEEi<0.031 mL/s/g) was compared to the merged second and third tertiles (MEEi≥0.031). RESULTS: Patients in the lowest MEEi tertile were older, had higher systolic blood pressure and body mass index. They also had higher prevalence of LV hypertrophy, whereas lower resting and stress MBF/mass ratio. MEEi was significantly correlated with both resting (r=0.51; P<0.0001) and hyperemic (r=0.54; P<0.0001) MBF/mass ratios, whereas it was not related to myocardial flow reserve. Delta of MBF/mass ratio was lower in the lowest MEEi tertile than in the highest (P<0.0001). In separate multiple linear regression models, after adjusting for sex, systolic blood pressure, body mass index, prevalence of LV hypertrophy, left atrial volume index, and diuretic therapy, the association between LV MEEi and both hyperemic (beta coefficient=0.44; P=0.003) and resting (beta coefficient=0.35; P=0.008) MBF/mass ratio remained significant. CONCLUSIONS: In hypertensive patients without flow-limiting epicardial coronary artery disease, low values of MEEi could detect an early LV dysfunction involving an impairment of both resting and hyperemic MBF/mass ratios. MEEi has the advantage of simpler detection, cheaper costs than positron emission tomography/computed tomography, and a lack of radiation exposure. REGISTRATION: URL: https://www.

RESUMEN

Background: Adverse drug reactions (ADRs) remain among the leading causes of therapy-resistant hypertension (TRH) and uncontrolled blood pressure (BP). We have recently reported beneficial results in BP control in patients with TRH adopting an innovative approach, defined as therapeutic concordance, in which trained physicians and pharmacists reach a concordance with patients to make them more involved in the therapeutic decision-making process. Methods: The main scope of this study was to investigate whether the therapeutic concordance approach could lead to a reduction in ADR occurrence in TRH patients. The study was performed in a large population of hypertensive subjects of the Campania Salute Network in Italy (ClinicalTrials.gov Identifier: NCT02211365). Results: We enrolled 4,943 patients who were firstly followed-up for 77.64 ± 34.44 months, allowing us to identify 564 subjects with TRH. Then, 282 of these patients agreed to participate in an investigation to test the impact of the therapeutic concordance approach on ADRs. At the end of this investigation, which had a follow-up of 91.91 ± 54.7 months, 213 patients (75.5%) remained uncontrolled while 69 patients (24.5%, p < 0.0001) reached an optimal BP control. Strikingly, during the first follow-up, patients had complained of a total of 194 ADRs, with an occurrence rate of 68.1% and the therapeutic concordance approach significantly reduced ADRs to 72 (25.5%). Conclusion: Our findings indicate that the therapeutic concordance approach significantly reduces ADRs in TRH patients.

RESUMEN

INTRODUCTION: An empathetic approach may be particularly useful in patients with therapy-resistant hypertension (TRH), defined as the failure to achieve target blood pressure (BP) despite a maximal doses of 3 antihypertensive drugs including a diuretic. However, the effects of therapeutic concordance have not been determined in hypertensive patients. METHODS: We designed a study to explore the impact of therapeutic concordance in patients with TRH, who were included in an intervention arm based on a protocol in which trained personnel periodically verified the pharmacological regimen of these patients. RESULTS: From a cohort of 5331 hypertensive patients followed-up for 77.64 ± 34.44 months, 886 subjects were found to have TRH; of these, 322 had apparent TRH (aTRH: uncontrolled office BP but optimal home BP) and 285 refused to participate in a second follow-up study, yielding a population of 279 patients with true TRH (tTRH). These tTRH patients were followed according to the therapeutic concordance protocol for 91.91 ± 54.7 months, revealing that 210 patients (75.27%) remained with uncontrolled BP (uncontrolled tTRH, Group I) while 69 patients (24.73%) reached an optimal BP control (average BP <140/90 mmHg in at least 50% of follow-up visits, Group II). Strikingly, at the end of the second follow-up, the percentage of patients displaying a decline in kidney function was significantly smaller in Group II than in Group I (8.5% vs 23.4%, p < 0.012). CONCLUSIONS: Taken together, our findings indicate for the first time that therapeutic concordance significantly improves the outcome of antihypertensive treatment in a population of patients with TRH.

RESUMEN

Background: Arterial hypertension, especially when coexisting with other cardiovascular risk factors, could determine an imbalance between myocardial energetic demand and altered efficiency, leading to an early left ventricular (LV) systolic dysfunction, even in terms of echo-derived mechano-energetic efficiency indexed for myocardial mass (MEEi). We aim to analyse an improvement in LV MEEi, if any, in a population of hypertensive patients with a long-term follow-up and to identify clinical, metabolic and therapeutic determinants of LV MEEi amelioration. Materials and methods: In total, 7,052 hypertensive patients, followed-up for 5.3 ± 4.5 years, enrolled in the Campania Salute Network, underwent echocardiographic and clinical evaluation. LV MEEi was obtained as the ratio between stroke volume and heart rate and normalized per grams of LV mass and ΔMEEi was calculated as difference between follow-up and baseline MEEi. Patients in the highest ΔMEEi quartile (≥0.0454 mL/s/g) (group 1) were compared to the merged first, second and third quartiles (<0.0454 mL/s/g) (group 2). METS-IR (Metabolic Score for Insulin Resistance), an established index of insulin sensitivity, was also derived. Results: Patients with MEEi improvement experienced a lower rate of major cardiovascular events (p = 0.02). After excluding patients experiencing cardiovascular events, patients in group 1 were younger (p < 0.0001), less often diabetic (p = 0.001) and obese (p = 0.035). Group 1 experienced more frequently LV mass index reduction, lower occurrence of LV ejection fraction reduction, and had a better metabolic control in terms of mean METS-IR during the follow-up (all p < 0.0001). Beta-blockers were more often used in group 1 (p < 0.0001) than group 2. A logistic regression analysis showed that younger age, lower mean METS-IR values, more frequent LV mass index reduction and therapy with beta-blockers were significantly associated with LV MEEi improvement, independently of presence of diabetes and obesity. Conclusion: Metabolic control and therapy with beta-blockers could act in a synergic way, determining an improvement in LV MEEi in hypertensive patients over time, possibly confining cardiac damage and hampering progression toward heart failure.

RESUMEN

BACKGROUND: Emerging evidence suggests that elevated circulating levels of HDL-C (high-density lipoprotein cholesterol) could be linked to an increased mortality risk. However, to the best of our knowledge, the relationship between HDL-C and specific cardiovascular events has never been investigated in patients with hypertension. METHODS: To fill this knowledge gap, we analyzed the relationship between HDL-C levels and cardiovascular events in hypertensive patients within the Campania Salute Network in Southern Italy. RESULTS: We studied 11 987 patients with hypertension, who were followed for 25 534 person-years. Our population was divided in 3 groups according to the HDL-C plasma levels: HDL-C<40 mg/dL (low HDL-C); HDL-C between 40 and 80 mg/dL (medium HDL-C); and HDL-C>80 mg/dL (high HDL-C). At the follow-up analysis, adjusting for potential confounders, we observed a total of 245 cardiovascular events with a significantly increased risk of cardiovascular events in the low HDL-C group and in the high HDL-C arm compared with the medium HDL-C group. The spline analysis revealed a nonlinear U-shaped association between HDL-C levels and cardiovascular outcomes. Interestingly, the increased cardiovascular risk associated with high HDL-C was not confirmed in female patients. CONCLUSIONS: Our data demonstrate that there is a U-shaped association between HDL-C and the risk of cardiovascular events in male patients with hypertension.
