Sex Moderates the Relationship Between Social Support and Cardiovascular Prevention Behaviors in Middle-aged and Older Adults.

BACKGROUND: Most risk factors for cardiovascular disease (CVD) are modifiable, suggesting that the burden of CVD could be substantially reduced through cardiovascular screening and healthier lifestyle. People who have social support are more likely to adhere to cardiovascular prevention recommendations, but it is not clear whether the benefit of social support is equal for men and women. PURPOSE: We investigated whether sex moderates the relationship between social support and adherence to cardiovascular prevention recommendations in a nationally representative sample. METHODS: Participants were 17,287 adults (n = 10,264 middle-aged adults 40-64 years old and n = 7,023 older adults ≥ 65 years old) who participated in the National Health Survey of Spain in 2017. Social support was measured with the Functional Social Support Questionnaire of Duke-UNC. Adherence to cardiovascular screening recommendations was assessed based on self-reported testing of cholesterol, blood pressure, and blood sugar by a health professional in the past 12 months. Adherence to recommended health-related behaviors was assessed based on the guidelines of the European Society of Cardiology regarding diet, alcohol consumption, smoking, and physical activity. RESULTS: Multiple regression models adjusted for socio-demographic and cardiovascular history and risk variables showed that social support was more strongly associated with adherence to cardiovascular prevention recommendations in men than in women. In particular, low social support levels were especially detrimental for both middle-aged men (screening: B = 0.13, 95% CI [0.06-0.20], p < .001; behaviors: B = 0.33 [0.26-0.41], p < .001) and older men (screening: B = 0.10 [0.04-0.17], p = .001; behaviors: B = 0.16 [0.08-0.25], p < .001), whereas older women had comparatively high adherence, which was unrelated to social support (screening: B = 0.02 [-0.03 to 0.08], p = .433; behaviors: B = 0.03 [-0.03 to 0.10], p = .342). CONCLUSIONS: Social support is more strongly associated with cardiovascular prevention in men than in women, such that men who lack social support have the lowest adherence to cardiovascular screening and lifestyle recommendations.

To help prevent cardiovascular disease, experts recommend screening for cardiovascular risk factors and leading a healthy lifestyle. Previous research has found that people who have social support are more likely to adhere to such cardiovascular prevention recommendations. In this study, using data form a nationally representative survey, we investigated whether the relationship between social support and adherence to cardiovascular prevention recommendations is different for men and women. Participants were 17,287 adults from the National Health Survey of Spain, who reported their cardiovascular screening history (i.e., whether they had their cholesterol, blood pressure, and blood sugar levels tested by a health professional in the past 12 months) and their lifestyle habits regarding diet, alcohol consumption, smoking, and physical activity. Social support was more strongly associated with cardiovascular prevention in men than in women, such that men who lacked social support had the lowest adherence to cardiovascular screening and lifestyle recommendations.

Social support buffers the negative effects of stress in cardiac patients: a cross-sectional study with acute coronary syndrome patients.

Cardiac patients who have social support generally have better prognosis than patients who lack social support. Several theoretical mechanisms have been proposed to explain this protective effect, including the capacity of social support to buffer the negative effects of stress. We tested this buffering effect in a study of patients hospitalized for acute coronary syndrome (ACS) in Spain. Several days after the cardiac event patients answered a questionnaire measuring stressful events during their lifetime, perceived social support around the time of the cardiac event, and depression symptoms in the past week. Results showed that stressful life events were related to depressive symptoms and worse renal function post-ACS only among patients with low perceived social support. Among patients who reported enough social support, lifetime stress was not related to depressive symptoms. No similar effects were observed on other prognostic indicators such as troponin levels or the number of obstructed arteries. These results suggest that social support can buffer the negative effects of stress on the mental and physical well-being of cardiac patients.

Numeracy Predicts Risk of Pre-Hospital Decision Delay: a Retrospective Study of Acute Coronary Syndrome Survival.

BACKGROUND: Many patients delay seeking medical attention during acute coronary syndromes (ACS), profoundly increasing their risk for death and major disability. Although research has identified several risk factors, efforts to improve patient decision making have generally been unsuccessful, prompting a call for more research into psychological factors. PURPOSE: The purpose of this study is to estimate the relationship between ACS decision delay and numeracy, a factor closely related to general decision making skill and risk literacy. METHODS: About 5 days after experiencing ACS, 102 survivors (mean age = 58, 32-74) completed a questionnaire including measures of numeracy, decision delay, and other relevant factors (e.g., anxiety, depression, symptom severity, knowledge, demographics). RESULTS: Low patient numeracy was related to longer decision delay, OR = 0.64 [95 % confidence interval (CI) 0.44, 0.92], which was in turn related to higher odds of positive troponin on arrival at the hospital, OR = 1.37 [95 % CI 1.01, 2.01]. Independent of the influence of all other assessed factors, a patient with high (vs. low) numeracy was about four times more likely to seek medical attention within the critical first hour after symptom onset (i.e., ORhigh-low = 3.84 [1.127, 11.65]). CONCLUSIONS: Numeracy may be one of the largest decision delay risk factors identified to date. Results accord with theories emphasizing potentially pivotal roles of patient deliberation, denial, and outcome understanding during decision making. Findings suggest that brief numeracy assessments may predict which patients are at greater risk for life-threatening decision delay and may also facilitate the design of risk communications that are appropriate for diverse patients who vary in risk literacy.

Recognizing a Heart Attack: Patients' Knowledge of Cardiovascular Risk Factors and Its Relation to Prehospital Decision Delay in Acute Coronary Syndrome.

In acute coronary syndromes (ACSs), longer decision delay - the time patients wait before seeking medical attention after symptoms have started - increases the risk of complications and death. However, many patients wait much longer than recommended and research is needed investigating how patient decision delay can be reduced. In a cross-sectional study of 120 ACS survivors, we investigated the relationship between knowledge of cardiovascular risk factors and decision delay. Several days after the onset of a cardiac event, patients completed a questionnaire measuring demographics, decision delay, objective knowledge of cardiovascular risks factors and of ACS symptoms, and subjective perceptions of symptoms during the cardiac episode. Relevant clinical data were extracted from patients' medical records. In a multiple linear regression analysis, controlling for demographic and clinical factors, objective knowledge of cardiovascular risk factors and ACS symptoms, and subjective attributions of symptoms to a cardiac cause were related to shorter decision delays. Among patients with relatively high knowledge of risk factors, only 5% waited more than 1 h to seek help, compared to 22% among patients with relatively low knowledge. These results suggest that knowledge of the factors that increase the risk of developing cardiovascular disease could play a role in patient decision making during an acute cardiac event. We discuss methodological issues and potential underlying mechanisms related to decision heuristics and biases, which can inform future research.

Psychosocial markers of pre-hospital decision delay and psychological distress in acute coronary syndrome patients.

Objectives Both pre-hospital decision delay - the time patients wait before seeking medical attention after symptoms have started - and high psychological distress after the cardiac episode predict poor prognosis of patients with acute coronary syndromes (ACS). We aimed to identify psychosocial markers of these prognostic factors. Design A cross-sectional study of 102 consecutive, clinically stable ACS survivors. Methods Participants completed a questionnaire measuring pre-hospital decision delay, psychological distress, and several known psychosocial factors related to cardiovascular health: type D personality, resilience, social support, and concerns during the cardiac event. Multiple linear regression and mediation analyses were conducted. Results Type D personality and fewer concerns about the serious consequences of delaying help-seeking were related to more psychological distress post-ACS, and these relationships were mediated by longer pre-hospital decision delay. In contrast, resilience was related to lower psychological distress. Social support and social concerns about help-seeking were not related to the outcome variables. Conclusions Type D personality may be a risk factor for more delayed help-seeking for an ACS and higher psychological distress after the cardiac event. Resilience, in contrast, emerged as a potential protective factor of patients' mental health after the cardiac event. Pre-hospital decision delay was related to thinking about serious consequences (e.g., complications, protecting one's family) but not about social concerns (e.g., wasting other people's time) during the cardiac episode. Statement of Contribution What is already known on this subject? Longer pre-hospital decision delay, that is waiting longer to seek medical attention after symptoms have started, predicts poor prognosis of acute coronary syndrome patients. High psychological distress post-ACS, such as the development of anxiety and/or depression, also predicts poor prognosis of these patients. What does this study adds? This study identifies several psychosocial markers of longer prehospital decision delay and high psychological distress post-ACS. Prehospital decision delay was related to thinking about serious consequences (e.g., complications, protecting one's family) but not about social concerns (e.g., wasting other people's time) during the cardiac episode. Type D personality and fewer concerns about the serious consequences of delaying help-seeking were related to more psychological distress, and these relationships were mediated by longer prehospital decision delay. Resilience was related to lower psychological distress post-ACS.

Who does what the cardiologist recommends? Psychosocial markers of unhealthy behavior in coronary disease patients.

Patients diagnosed with coronary heart disease should follow lifestyle recommendations that can reduce their cardiovascular risk (e.g., avoid smoking). However, some patients fail to follow these recommendations and engage in unhealthy behavior. With the aim to identify psychosocial factors that characterize patients at high risk of repeated cardiovascular events, we investigated the relationship between social support, mental health (coping, self-esteem, and perceived stress), and unhealthy behavior. We conducted a cross-sectional study of 419 patients recently diagnosed with coronary heart disease (myocardial infarction or angina) who participated in the National Health Survey in Spain (2018). Unhealthy behaviors were defined according to the European Guidelines on cardiovascular disease prevention. Only 1% of patients reported no unhealthy behaviors, with 11% reporting one, 40% two, 35% three, and 13% four or more unhealthy behaviors. In multiple regression controlling for demographic and traditional risk factors, mental health was the only significant psychosocial factor, doubling the odds of accumulated unhealthy behaviors, OR(high vs. low) = 2.03, 95% CI [1.14, 3.64]. Mental health was especially strongly related to unhealthy behavior among patients with obesity, OR(high vs. low) = 3.50, 95% CI [1.49, 8.45]. The relationship between mental health and unhealthy behaviors suggests that a large proportion of patients may not adhere to lifestyle recommendations not because they purposefully choose to do so, but because they lack coping skills to maintain the recommended healthy behaviors. Low mental well-being may be especially detrimental for behavior change of patients with obesity.

Psychological and cognitive factors related to prehospital delay in acute coronary syndrome: A systematic review.

BACKGROUND: In acute coronary syndrome the time elapsed between the start of symptoms and the moment the patient receives treatment is an important determinant of survival and subsequent recovery. However, many patients do not receive treatment as quickly as recommended, mostly due to substantial prehospital delays such as waiting to seek medical attention after symptoms have started. OBJECTIVE: To conduct a systematic review with meta-analysis of the relationship between nine frequently investigated psychological and cognitive factors and prehospital delay. DESIGN: A protocol was preregistered in PROSPERO [CRD42018094198] and a systematic review was conducted following PRISMA guidelines. DATA SOURCES: The following databases were searched for quantitative articles published between 1997 and 2019: Medline (PubMed), Web of Science, Scopus, Psych Info, PAIS, and Open grey. REVIEW METHODS: Study risk of bias was assessed with the NIH Quality Assessment Tool for Observational, Cohort, and Cross-Sectional Studies. A best evidence synthesis was performed to summarize the findings of the included studies. RESULTS: Forty-eight articles, reporting on 57 studies from 23 countries met the inclusion criteria. Studies used very diverse definitions of prehospital delay and analytical practices, which precluded meta-analysis. The best evidence synthesis indicated that there was evidence that patients who attributed their symptoms to a cardiac event (n = 37), perceived symptoms as serious (n = 24), or felt anxiety in response to symptoms (n = 15) reported shorter prehospital delay, with effect sizes indicating important clinical differences (e.g., 1.5-2 h shorter prehospital delay). In contrast, there was limited evidence for a relationship between prehospital delay and knowledge of symptoms (n = 18), concern for troubling others (n = 18), fear (n = 17), or embarrassment in asking for help (n = 14). CONCLUSIONS: The current review shows that symptom attribution to cardiac events and some degree of perceived threat are fundamental to speed up help-seeking. In contrast, social concerns and barriers in seeking medical attention (embarrassment or concern for troubling others) may not be as important as initially thought. The current review also shows that the use of very diverse methodological practices strongly limits the integration of evidence into meaningful recommendations. We conclude that there is urgent need for common guidelines for prehospital delay study design and reporting.

Results of genotype-guided antiplatelet therapy in patients who undergone percutaneous coronary intervention with stent.

BACKGROUND: Clopidogrel has provided beneficial effects in acute coronary syndrome and percutaneous coronary intervention. Different polymorphisms have been associated with differences in clopidogrel response. The aim of this study was to check if CYP2C19/ABCB1-genotype-guided strategy reduces the rates of cardiovascular events and bleeding. METHODS: This experimental study included patients undergoing percutaneous coronary intervention with stent. The prospective genotype-guided strategy (intervention group) was compared against a retrospective non-tailored strategy (control group). Primary efficacy endpoint was the composite of cardiovascular death, acute coronary syndrome or stroke during 12months after intervention. Secondary endpoint was to compare the efficacy of the different antiplatelet therapies used in genotyping conditions. RESULTS: The study included 719 patients undergone stent, more than 86% with acute coronary syndrome. The primary endpoint occurred in 32 patients (10.1%) in the genotyping group and in 59 patients (14.1%) in the control group (HR 0.63, 95% CI (0.41-0.97), p =0.037). There was no difference in The Thrombolysis in Myocardial Infarction major and minor bleeding criteria between the two groups (4.1% vs. 4.7%, HR=0.80, 95% CI (0.39-1.63), p=0.55). In intervention group, there was no difference in the rate of events in patients treated with clopidogrel versus patients treated with other antiplatelet treatments (9.1% vs 11.5% p=0.44), or bleeding (3.7% vs 4.6%, p=0.69). CONCLUSIONS: The genotype-guided strategy could reduce the rates of composite of cardiovascular events and bleeding during 12months after percutaneous coronary intervention compared to a non-genotype-guide strategy.

Coronary microvascular spasm triggers transient ischemic left ventricular diastolic abnormalities in patients with chest pain and angiographically normal coronary arteries.

AIMS: Impaired coronary microvascular dilatory function can lead to exercise induced myocardial ischemia and angina pectoris even in patients without significant (>50%) obstructive coronary atherosclerosis (APWOCA). Diffuse distal vessel epicardial spasm and microvascular spasm have been also proposed as a plausible explanation for angina at rest in these patients. However, objective systematic evidence for the latter i.e. echocardiographic wall motion abnormalities during angina, is lacking at present. Coronary epicardial and microvascular spasm can be triggered in susceptible patients by the administration of intracoronary acetylcholine (Ach). We sought to assess whether Ach induced diffuse distal epicardial coronary artery spasm (≥75% diameter reduction) and coronary microvascular spasm can cause transient ischemic left ventricular dysfunction, as assessed by echocardiography. METHODS: 50 patients (19 men aged 60.5 ± 8.9 years) with stable APWOCA were assessed for coronary spasm and myocardial ischemia with intracoronary Ach infusion, 2D transthoracic echocardiography (before and during Ach testing), continuous 12-lead ECG monitoring, and ultrasensitive cardiac troponin (US-cTn) measurement before and within 4 h after Ach testing. RESULTS: 14 patients (28%) had a "negative" Ach test, 14 (28%) developed coronary microvascular spasm and 17 (34%) had diffuse distal epicardial spasm. In 5 patients (10%) the test was inconclusive. Echocardiographic variables including deceleration time, EF slope and E/A, as well as ultrasensitive-cTn concentrations were abnormal during Ach induced ischemic ECG changes. CONCLUSIONS: We have, for the first time, demonstrated that Ach induced coronary microvascular spasm is associated with echocardiographic changes and ultrasensitive-cTn elevations, indicative of myocardial ischemia.
