RESUMO

OBJECTIVE: The electrocardiogram-derived corrected QT (QTc) interval is an indicator of cardiac autonomic activity that has been proposed as a biological measure to investigate the interplay between depression and cardiovascular diseases. This study assesses whether depression is associated with a longer QTc interval across age groups. METHODS: Assessment of depressive symptoms was performed in 1637 participants of the cross-sectional Corinthia study with the Zung Self-Rating Depression Scale in those younger than 65 years (group 1) and with the Geriatric Depression Scale in elderly individuals (≥65 years, group 2). The QT interval was obtained from electrocardiogram recordings and corrected for heart rate (QTc). RESULTS: Individuals in group 1 with depression were predominantly women and had a higher prevalence of coronary artery disease and diabetes mellitus. Group 1 individuals with depression had longer QTc duration (no depression versus depression, 389.3 [27.0] versus 401.1 [32.9] milliseconds; p < .001) and percentage of abnormal QTc (no depression versus depression, 2.0% versus 10.8%; p = .001) compared with those without depression. Elderly individuals (group 2) had similar values of QTc and percentage of abnormal QTc irrespective of depression status. Even after adjustment for known QT-prolonging factors, the presence of depression in younger individuals was associated with an increased QTc by 11.1 milliseconds and with an approximately 10.6-fold higher prevalence of abnormal QTc duration. CONCLUSIONS: Depression was associated with a longer QTc interval especially in individuals younger than 65 years. These findings may indicate an interrelationship between depression and autonomic dysregulation as potential risk factors for cardiovascular disease and sudden cardiac death.

RESUMO

BACKGROUND AND AIMS: Evaluation of arterial stiffness and carotid atherosclerotic burden can provide important prognostic information regarding the risk of future cardiovascular events. The aim of this study was to assess these vascular properties in patients with diabetes mellitus (DM). METHODS AND RESULTS: In the context of the observational "Corinthia" study, we analyzed 1757 participants with determined DM status. Carotid ultrasonography was performed to evaluate intima-media thickness (cIMT) and carotid plaque burden. Arterial stiffness was estimated via assessment of carotid-to-femoral pulse wave velocity (cfPWV). Individuals with DM had increased mean cIMT, maximum cIMT, carotid plaque burden, and cfPWV compared to those without DM. After multivariable regression analysis, the presence of DM was still associated with significantly increased mean cIMT (by 0.074 mm, p = .004), maximum cIMT (by 0.134 mm, p = .007), cfPWV (by 0.929 m/s, p < .001), and a higher prevalence of carotid plaques (odds ratio 1.52, 95% confidence intervals 1.11, 2.10, p = .01). In a propensity score-matched cohort, mean cIMT, maximum cIMT, and carotid plaque burden were significantly higher in individuals with DM. Analysis according to territory of cIMT measurement displayed substantial differences in left (DM: 1.32 ± 0.78 mm vs. no DM: 1.20 ± 0.66 mm, p = .04) and right carotid bulbs (DM: 1.33 ± 0.82 mm vs. no DM: 1.18 ± 0.69 mm, p = .02) with respect to DM status while non-significant variations were observed in left (DM: 0.98 ± 0.49 mm vs. no DM: 0.91 ± 0.35 mm, p = .06) and right common carotid artery (DM: 0.95 ± 0.50 mm vs. no DM: 0.92 ± 0.40 mm, p = .36). CONCLUSIONS: Diabetes mellitus is associated with increased cfPWV and cIMT, with more pronounced lesions in the carotid bulb.

RESUMO

BACKGROUND: Acute pericarditis has a wide spectrum of clinical presentations largely depending on underlying aetiologies. We assessed the role of age and sex in the clinical features and outcome of acute pericarditis. MATERIALS AND METHODS: A total of 240 consecutive patients hospitalized with a first episode of acute pericarditis were included. At baseline demographics, clinical features, laboratory and imaging findings and medical therapy were recorded. Patients were followed up for at least 18 months for complications. Data comparisons were performed according to sex and age (≤60 or >60 years). RESULTS: The male/female ratio was 1.42, and 56% of patients were >60 years. Younger patients depicted more often chest pain (P = .001), fever and rubs (P < .001 for both), ST elevation and PR depression (P = .032 and .009, respectively), higher CRP values (P = .009) and less often dyspnoea (P = .046) and pericardial effusion (P = .036). Moreover, they received less often glucocorticoids (P < .001) and depicted less atrial fibrillation (P = .003) and a higher rate of recurrent pericarditis (P = .013). After multivariate adjustment for confounders, age >60 years remained an independent predictor for a lower risk of recurrent pericarditis (hazard ratio 0.60, 95% CI: 0.39-0.96, P = .033). Regarding sex, females were older (P = .007), showed less often ST elevation and PR depression (P < .001 and .002, respectively) and had a higher baseline heart rate (P = .02). Sex was not associated with recurrent pericarditis risk. CONCLUSIONS: Patients with acute pericarditis have distinct presenting clinical, biochemical and prognostic features according to age and sex. Awareness of such differences is important for clinical decision-making.

RESUMO

PURPOSE: Sleep is an essential physiologic process whose disturbances have been regarded as a risk factor in various pathophysiologic processes, including atherosclerosis and cardiovascular disease. Although the negative influence of short sleep duration has been well-established, recent data suggest a possible harmful effect of prolonged sleeping pattern. METHODS: In the setting of the Corinthia cross-sectional study, self-reported night sleep duration was recorded in 1752 apparently healthy individuals and was classified as normal sleep duration (NSD, 7-8 h), short sleep duration (SSD, 6-7 h), very short sleep duration (VSSD, < 6 h), and long sleep duration (LSD, > 8 h). Carotid duplex ultrasonography was performed in order to measure the mean and maximum carotid intima-media thickness (cIMT) as a non-invasive marker of atherosclerosis. RESULTS: Subjects with LSD and VSSD had significantly higher mean cIMT (VSSD: 1.02 ± 0.45 mm, SSD: 0.95 ± 0.35, NSD: 0.96 ± 0.38 mm, LSD: 1.07 ± 0.52 mm; p < 0.001) and maximum cIMT (VSSD: 1.39 ± 0.9 mm, SSD: 1.25 ± 0.71 mm, NSD: 1.23 ± 0.76 mm, LSD: 1.41 ± 0.93 mm). Following a regression analysis adjusting for known cardiovascular risk factors, individuals with LSD and VSSD had higher mean cIMT by 0.054 mm and 0.067 mm respectively compared to those with NSD. CONCLUSION: A balanced sleeping duration of 6-8 h is associated with decreased mean and maximum IMT while both very short sleep duration and long sleep duration are associated with increased carotid intima-media thickness, a marker of subclinical atherosclerosis.

RESUMO

BACKGROUND: Electrocardiogram (ECG) is considered the initial screening method for the detection of left ventricular hypertrophy (LVH) despite its low sensitivity. However, there are no data on how ECG criteria for LVH perform in patients with concentric (cLVH) and eccentric LVH (eLVH). METHODS: In the setting of the Corinthia cross-sectional study, ECGs were analyzed in 1,570 participants of the study. Seven ECG LVH criteria were calculated (Sokolow-Lyon voltage, index, and product, sex-specific Cornell voltage and product, Lewis voltage, and the Framingham), whereas LVH was defined, based on echocardiographic data, as left ventricular mass indexed for body surface area (BSA) of at least 125 g/m2 in men and at least 110 g/m2 in women. RESULTS: Regarding the frequency encountered for each ECG LVH criterion, there was no difference between eLVH and cLVH. However, when ECG criteria were compared as continuous variables between LVH groups, Cornell voltage and product were higher in cLVH individuals, with a value of Cornell voltage >13.95 mV having 61% sensitivity and 62% specificity to differentiate cLVH from eLVH (p = .05). Even after adjustment for age, sex, body mass index, and hypertension, the occurrence of Cornell voltage or product increased the odds of cLVH by 1.6 times (p = .001). CONCLUSION: Cornell voltage and product criteria disclosed a superior discriminative ability for the detection of LVH via ECG. When further categorizing LVH as concentric and eccentric, Cornell product depicted the higher discriminative ability for cLVH.

RESUMO

BACKGROUND AND AIMS: The role of dietary patterns, in cardiovascular diseases has been challenged. The role of breakfast as an element of balance energy intake has gained research interest. However, the effects of dietary patterns related to breakfast consumption on vascular function are unknown. We explored the association of breakfast consumption habits with arterial wall elastic properties and carotid atherosclerosis. METHODS AND RESULTS: In this cross-sectional study we enrolled 2043 inhabitants of the Corinthia region in Greece. Carotid-femoral pulse wave velocity (cf-PWV) was used to assess arterial stiffness. Carotid intima-media thickness (cIMT) was measured and the mean and the maximum cIMT were calculated. According to food frequency questionnaires, breakfast contribution in total daily energy intake (>20%; 5-20% and <5%) was estimated. Subjects were categorized as high-energy breakfast consumers (HeBC), low-energy breakfast consumers (LeBC) and those skipping breakfast (SBf) respectively. From the study population 240 subjects were categorized as HeBC, 897 as LeBC, and 681 as SBf. The mean cf-PWV was significantly higher in subjects SBf compared to LeBC and HeBC (9.35 ± 2.82 m/s vs. 9.09 ± 2.77 m/s vs. 8.76 ± 2.69 m/s, p = 0.02). The mean cIMT was significantly higher in subjects SBf compared to LeBC and HeBC (1.04 ± 0.46 mm vs. 0.99 ± 0.43 mm vs. 0.92 ± 0.39 mm, p = 0.01). Even after adjustment for potential confounders and cardiovascular risk factors SBf subjects have significantly increased mean cIMT and cf-PWV. CONCLUSION: Skipping breakfast has an adverse effect on arterial stiffness and carotid atheromatic burden. Increased breakfast total energy intake may act protectively against atherosclerosis, a finding worth of further pathophysiologic exploration with potential clinical implications.

RESUMO

Background: The 2017 ACC/AHA blood pressure (BP) guidelines generated controversies due to the new proposed BP cut-off values defining hypertension. We aimed to assess aortic stiffness of subjects who are reclassified as stage 1 hypertensive according to the new guidelines and compare them with the subjects of "elevated BP" category. Patients and methods. Data from the "Corinthia" study, an observational, cross-sectional survey of 2,043 participants were analyzed. Subjects were classified into 4 groups: group A: systolic pressure (SBP) 120-129 and diastolic pressure (DBP) < 80 mmHg, group B: SBP 130-139 or DBP 80-89 mmHg, group B1: SBP 130-139 and DBP < 80 mmHg and group B2: SBP 130-139 and DBP 80-89 mmHg. Aortic stiffness was assessed by carotid-to-femoral pulse wave velocity (PWV). A value of PWV > 10m/s was consider indicative of asymptomatic organ damage while values of PWV exceeded the 90 % percentile for each age group were consider as abnormal. Results: Groups B, B1 and B2 have significantly increased PWV compared to group A, independently from age and other risk factors (PWV: 9.2 ± 2.8 vs 9.4 ± 2.7 vs 8.6 ± 2.5 vs 8.1 ± 2.3 m/s, p < 0.01, respectively). The prevalence of PWV > 10 m/s and abnormal PWV values in group A was significantly lower than the corresponding prevalence in randomly selected, age-matched subjects from group B (13.5 % vs 24.4 %, p = 0.027 and 5.6 % vs 14.2 %, p = 0.022, respectively). Conclusions: The reclassified subjects as stage 1 hypertensive by the new guidelines have a significantly increased aortic stiffness and greater prevalence in asymptomatic aortic damage compared to subjects with elevated BP. This finding may indirectly explain the increased cardiovascular risk of this group.

RESUMO

Heart failure (HF) is a common cardiac syndrome, whose pathophysiology involves complex mechanisms, some of which remain unknown. Diabetes mellitus (DM) constitutes not only a glucose metabolic disorder accompanied by insulin resistance but also a risk factor for cardiovascular disease and HF. During the last years though emerging data set up, a bidirectional interrelationship between these two entities. In the case of DM impaired calcium homeostasis, free fatty acid metabolism, redox state, and advance glycation end products may accelerate cardiac dysfunction. On the other hand, when HF exists, hypoperfusion of the liver and pancreas, b-blocker and diuretic treatment, and autonomic nervous system dysfunction may cause impairment of glucose metabolism. These molecular pathways may be used as therapeutic targets for novel antidiabetic agents. Peroxisome proliferator-activated receptors (PPARs) not only improve insulin resistance and glucose and lipid metabolism but also manifest a diversity of actions directly or indirectly associated with systolic or diastolic performance of left ventricle and symptoms of HF. Interestingly, they may beneficially affect remodeling of the left ventricle, fibrosis, and diastolic performance but they may cause impaired water handing, sodium retention, and decompensation of HF which should be taken into consideration in the management of patients with DM. In this review article, we present the pathophysiological data linking HF with DM and we focus on the molecular mechanisms of PPARs agonists in left ventricle systolic and diastolic performance providing useful insights in the molecular mechanism of this class of metabolically active regiments.

RESUMO

OBJECTIVE: The aim of the present study was to assess the level of access site pain in patients undergoing transradial coronary catheterization by using topical application of an anesthetic ointment (lidocaine/prilocaine-AO) compared to standard local anesthesia (LA) by means of injectable lidocaine. METHODS: We prospectively studied 444 patients undergoing elective trans-radial coronary angiography. The quality of analgesia was assessed using a visual analogue scale (VAS) immediately after the puncture and 30 min after the removal of the sheath. The number and duration of attempts before successful sheath insertion, as well as artery spasm, were compared between the two groups. RESULTS: Pain levels measured by VAS were found to be similar between the two groups during sheath insertion (VAS: AO: 4.84 ± 1.0 vs 4.82 ± 1.2, P = NS), as well as 30 min after sheath removal (VAS: AO: 0.07 ± 0.5 vs LA: 0.15 ± 0.6, P = NS). The time to obtain radial access was also not affected by the use of anesthetic ointment (AO: 62.24 ± 25.7 s vs LA: 64.04 ± 18.78 sec, P = NS). The rate of clinical or angiographic radial artery spasm was similar (8-10%) between the groups (P = NS) CONCLUSION: Use of a local anesthetic ointment, versus injectable lidocaine, in trans-radial cardiac catheterization as means of local anesthesia, was found to be equally effective in terms of pain, artery spasm, or artery cannulation speed.

RESUMO

BACKGROUND: Several investigations have highlighted the role of water quality in cardiovascular health. In the present study, we have investigated the effects of drinking water hardness on atherosclerotic burden in carotid arteries and arterial stiffness. METHODS: "Corinthia" study was conducted in the homonym region in Greece from 2015 to 2017. Carotid atherosclerosis was assessed by intima-media thickness (IMT). Pulse wave velocity (PWV) was used to evaluate arterial stiffness. Tap-water samples were collected from the study area and analyzed for a variety of elements, as well as pH and total hardness. RESULTS: Individuals living in lower drinking water hardness areas (Area 1) versus individuals living in higher water hardness areas (Area 2) had lower max IMT (p = 0.004) and were less susceptible to carotid plaque formation (p = 0.004). Interestingly, individuals over 65 years from Area 1 had lower mean IMT, max IMT, and less plaque formation (p < 0.001 for all). The mean value of PWV in the overall study population was below the 10 m/s cutoff, which defines arterial stiffness (9.15 ± 2.79 m/s). Nevertheless, a marginally higher rate of vascular stiffening was noted in Area 2 vs. Area 1 (16.2% and 12.8%, respectively, p = 0.048). CONCLUSIONS: According to this cross-sectional study's findings, a positive association between extra hard water and carotid atherosclerotic burden was found. However, the association with arterial stiffness is unclear and should be investigated further.

RESUMO

BACKGROUND: A paravalvular leak (PVL) is a complication following valve replacement, which may lead to heart failure and hemolysis. The aim of this study is to investigate whether the clinical outcome after transcatheter PVL closure differs according to the prominent indication of the procedure (symptoms of heart failure or hemolysis). METHODS: The data of consecutive patients who had transcatheter treatment for PVL between July 2011 and September 2022 in five Greek centers were analyzed. The primary endpoint was the technical, and clinical success rates with regards to the prominent indication of paravalvular leak closure. The secondary endpoints included the evaluation and comparison of the clinical and technical success in relation to the type of valve that was treated (aortic or mitral) as well as the survival analysis in relation to the closure indication and type of valve that was treated. RESULTS: In total, 60 patients were retrospectively studied (39% men, mean age 69.5 ± 11 years). Regarding the primary outcomes, the technical success in patients mainly suffering from hemolysis was 86.1%, while in those presenting heart failure it was 95.8%, p = 0.387. Furthermore, the clinical success was 72.2% and 87.5% among hemolysis and heart failure patients, respectively, p = 0.210. During the follow-up period, the two-year survival rates were significantly better for patients treated for the aortic valve (78.94%) compared to those in the mitral position (48.78%), p = 0.014. In total, 25 patients died (41.7%) during 24 months of follow-up. CONCLUSIONS: Transcatheter paravalvular leak closure can be performed with high technical and clinical success rates without any difference according to the prominent indication of closure.

RESUMO

Atherosclerotic cardiovascular diseases remain the leading cause of morbidity and mortality worldwide despite all efforts made towards their management. Other than targeting the traditional risk factors for their development, scientific interest has been shifted towards epigenetic regulation, with microRNAs (miRs) being at the forefront. MiR-126, in particular, has been extensively studied in the context of cardiovascular diseases. Downregulated expression of this miR has been associated with highly prevalent cardiovascular risk factors such as arterial hypertension and diabetes mellitus. At the same time, its diagnostic and prognostic capability concerning coronary artery disease is still under investigation, with up-to-date data pointing towards a dysregulated expression in a stable disease state and acute myocardial infarction. Moreover, a lower expression of miR-126 may indicate a higher disease complexity, as well as an increased risk for future major adverse cardiac and cerebrovascular events. Ultimately, overexpression of miR-126 may emerge as a novel therapeutic target in atherosclerotic cardiovascular diseases due to its potential in promoting therapeutic angiogenesis and anti-inflammatory effects. However, the existing challenges in miR therapeutics need to be resolved before translation to clinical practice.

RESUMO

Inherited cardiovascular diseases are highly heterogeneous conditions with multiple genetic loci involved. The application of advanced molecular tools, such as Next Generation Sequencing, has facilitated the genetic analysis of these disorders. Accurate analysis and variant identification are required to maximize the quality of the sequencing data. Therefore, the application of NGS for clinical purposes should be limited to laboratories with a high level of technological expertise and resources. In addition, appropriate gene selection and variant interpretation can result in the highest possible diagnostic yield. Implementation of genetics in cardiology is imperative for the accurate diagnosis, prognosis and management of several inherited disorders and could eventually lead to the realization of precision medicine in this field. However, genetic testing should also be accompanied by an appropriate genetic counseling procedure that clarifies the significance of the genetic analysis results for the proband and his family. In this regard, a multidisciplinary collaboration among physicians, geneticists, and bioinformaticians is imperative. In the present review, we address the current state of knowledge regarding genetic analysis strategies employed in the field of cardiogenetics. Variant interpretation and reporting guidelines are explored. Additionally, gene selection procedures are accessed, with a particular emphasis on information concerning gene-disease associations collected from international alliances such as the Gene Curation Coalition (GenCC). In this context, a novel approach to gene categorization is proposed. Moreover, a sub-analysis is conducted on the 1,502,769 variation records with submitted interpretations in the Clinical Variation (ClinVar) database, focusing on cardiology-related genes. Finally, the most recent information on genetic analysis's clinical utility is reviewed.

RESUMO

Recent advances in cardiovascular genetics have transformed genetic testing into a valuable part of management of families with inherited cardiomyopathies. As novel mutations have been identified, understanding when to consider genetic testing has emerged as an important consideration in the management of these cases. Specific genetic testing has a paramount importance in the risk stratification of family members, in the prognosis of probands at higher risk of a serious phenotype expression, and finally in the identification of new mutations, all of which are discussed in this review. The indications for each type of cardiomyopathy are described, along with the limitations of genetic testing. Finally, the importance of public sharing of variants in large data sets is emphasized. The ultimate aim of this review is to present key messages about the genetic testing process in order to minimize potential harms and provide suggestions to specialized clinicians who act as a part of a multidisciplinary team in order to offer the best care to families with inherited cardiomyopathies.

RESUMO

Cardiovascular disease remains the main cause of human morbidity and mortality in developed countries. Microparticles (MPs) are small vesicles originating from the cell membrane as a result of various stimuli and particularly of biological processes that constitute the pathophysiology of atherosclerosis, such as endothelial damage. They form vesicles that can transfer various molecules and signals to remote target cells without direct cell-to-cell interaction. Circulating microparticles have been associated with cardiovascular diseases. Therefore, many studies have been designed to further investigate the role of microparticles as biomarkers for diagnosis, prognosis, and disease monitoring. To this concept, the pro-thrombotic and atherogenic potential of platelets and endothelial-derived MPs have gained research interest, especially concerning accelerated atherosclerosis and triggering as well as prognosis of an acute coronary syndrome. MPs, especially those of endothelial origin, have been investigated in different clinical scenarios of heart failure and in association with left ventricular loading conditions. Finally, most cardiovascular risk factors present unique features in the circulating MPs population, highlighting their pathophysiologic link to cardiovascular disease progression. In this review article, we present a synopsis of the biogenesis and characteristics of microparticles, as well as the most recent data concerning their implication in cardiovascular settings.

RESUMO

Diminished physical activity is a frequent phenomenon leading to a higher incidence of cardiovascular morbidity and mortality. Our study aimed to assess the impact of physical activity on arterial stiffness and inflammation. Classification of physical activity was performed in 1945 individuals of the cross-sectional "Corinthia" study using the International Physical Activity Questionnaire. Demographic and clinical characteristics were obtained via a standardized questionnaire. Arterial stiffness was estimated via carotid-femoral pulse wave velocity evaluation, and the inflammatory burden was assessed via high sensitivity C reactive protein (hsCRP) measurement. Participants with low physical activity had the most impaired carotid-femoral pulse wave velocity values while abnormally increased measurements-adjusted for age and blood pressure-were more frequently encountered in individuals with low physical activity. Participants characterized as having vigorous physical activity had the lowest inflammatory burden, as estimated by hsCRP levels. The results remained unaffected even after adjustment for confounders. In a subgroup analysis according to sex, increased arterial stiffness and inflammatory burden were noted similarly in female and male subjects within the lowest percentile of physical activity. In conclusion, a significant association between physical activity, arterial stiffness, and inflammation was observed, even after adjusting for known cardiovascular risk factors.

RESUMO

Novel therapies in peripheral arterial disease, such as granulocyte colony-stimulating factor (GCSF) administration, might result in anti-atherosclerotic effects. In this study, we used 10-week-old male ApoE-/- mice, which were fed an atherosclerosis-inducing diet for four weeks. At the end of the four weeks, hind limb ischemia was induced through left femoral artery ligation, the atherosclerosis-inducing diet was discontinued, and a normal diet was initiated. Mice were then randomized into a control group (intramuscular 0.4 mL normal saline 0.9% for 7 days) and a group in which GCSF was administrated intramuscularly in the left hind limb for 7 days (100 mg/kg). In the GCSF group, but not in the control group, we observed significant reductions in the soluble adhesion molecules (vascular cell adhesion molecule-1 (sVCAM-1) and intercellular adhesion molecule-1 (sICAM-1)), sE-Selectin, and plasminogen activator inhibitor (PAI)-1 when they were measured through ELISA on the 1st and the 28th days after hind limb ischemia induction. Therefore, GCSF administration in an atherosclerotic mouse model of hind limb ischemia led to decreases in the biomarkers associated with endothelial activation and thrombosis. These findings warrant further validation in future preclinical studies.

RESUMO

The aim of this study was to evaluate several sociodemographic, lifestyle, and clinical characteristics of the IKARIA study participants and to find healthy aging trajectories of multimorbidity of Ikarian islanders. During 2009, 1410 people (aged 30+) from Ikaria Island, Greece, were voluntarily enrolled in the IKARIA study. Multimorbidity was defined as the combination of at least two of the following chronic diseases: hypertension; hypercholesterolemia; diabetes; obesity; cancer; CVD; osteoporosis; thyroid, renal, and chronic obstructive pulmonary disease. A healthy aging index (HAI) ranging from 0 to 100 was constructed using 4 attributes, i.e., depression symptomatology, cognitive function, mobility, and socializing. The prevalence of multimorbidity was 51% among men and 65.5% among women, while the average number of comorbidities was 1.7 ± 1.4 for men and 2.2 ± 1.4 for women. The most prevalent chronic diseases among men with multimorbidity were hypertension, hypercholesterolemia, and obesity while among women they were hypertension, hypercholesterolemia, and thyroid disease. Multimorbidity was correlated with HAI (Spearman's rho = -0.127, p < 0.001) and for every 10-unit increase in HAI, participants had 20% lower odds of being multimorbid. Multimorbidity in relation to HAI revealed a different trend across aging among men and women, coinciding only in the seventh decade of life. Aging is usually accompanied by chronic diseases, but multimorbidity seems to also be common among younger adults. However, healthy aging is a lifelong process that may lead to limited co-morbidities across the lifespan.
