Resistant hypertension: challenges in everyday practice.

Resistant hypertension is defined as not achieving sufficient control of blood pressure (BP), that is, maintaining BP values equal to or above 140/90 mm Hg when using 3 antihypertensive drugs, including diuretics, properly combined and at maximum doses. The uncontrolled treated hypertension should be confirmed in out­of­office BP measurements, preferably with 24­hour ambulatory BP monitoring. Demographic and clinical characteristics indicate that patients with resistant hypertension are older than the general population of patients with arterial hypertension and more often suffer from comorbidities. When resistant hypertension is suspected, it is necessary to assess whether optimal pharmacotherapy has been prescribed, including appropriate combinations of antihypertensive drugs and diuretics at appropriate doses. It is also important to exclude parallel use of drugs that may have unfavorable interactions leading to an increase in BP. A common cause of pseudoresistant hypertension is a patient's failure to comply with therapeutic recommendations, including a lack of lifestyle changes and nonadherence to the prescribed medication regimen. An important step in management of resistant hypertension is targeted screening with diagnostic tests for secondary hypertension. Expanding of the drug therapy beyond a 3­drug regimen should include a mineralocorticoid receptor antagonist, in particular spironolactone. In selected patients, device­based hypertension treatment might be considered.

Treatment goal attainment for secondary prevention in coronary patients with or without diabetes mellitus - Polish multicenter study POLASPIRE.

Introduction: Cardiovascular disease is still a leading cause of death in Poland and across Europe. The aim of this study was to assess the attainment of the main treatment goals for secondary cardiovascular prevention in coronary patients with or without diabetes mellitus (DM) in Poland. Material and methods: The study group included 1026 patients (65.5 ±9 y.o.; males: 72%) included at least 6 months after the index hospitalisation for myocardial infarction, unstable angina, elective percutaneous coronary intervention or coronary artery bypass surgery. The target and treatment goals were defined according to the 2016 European Society of Cardiology guidelines on cardiovascular prevention. Results: Patients with DM (n = 332; 32%) were slightly older compared to non-diabetic (n = 694) individuals (67.2 ±7 vs. 64.6 ±9 years old; p < 0.0001). The DM goal was achieved in 196 patients (60%). The rate of primary (LDL: 51% vs. 35%; p < 0.0001) and secondary (non-HDL: 56% vs. 48%; p < 0.02) goal attainment was higher in DM(+) compared to DM(-) patients. The rate of target blood pressure was lower in DM(+) than in normoglycemic patients (52% vs. 61% at < 140/90 mm Hg, p < 0.01. As expected, goal achievement of normal weight (9.5% vs. 19%; p < 0.0001) and waist circumference (7% vs. 15%; p < 0.001) was lower in diabetic patients and the rate of regular physical activity was similar (DM+ 12% vs. DM- 14%; p = ns). Finally, there was no difference in active smokers (DM+ 23% vs. DM- 22%; p = ns). Conclusions: Great majority of Polish patients in secondary prevention do not achieve treatment goals. Although lipid goals attainment is better in DM and the rate of smokers is similar, the management of all risk factors needs to be improved.

Trajectories of Blood Pressure in Patients with Established Coronary Artery Disease over 20 years.

Objective: To evaluate changes in blood pressure (BP) values in patients with established coronary artery disease (CAD) over 20 years (1997-2017). Materials and Methods: Consecutive patients aged <71 years and hospitalized for acute coronary syndrome or myocardial revascularization procedures were recruited and interviewed 6-18 months after their discharge from the hospital. BP was measured in 1997-1998, 1999-2000, 2006-2007, 2011-2013, and 2016-2017. The same five hospitals took part in the surveys at each time point. Results: We examined 412 patients in 1997-1998, 427 in 1999-2000, 422 in 2006-2007, 462 in 2011-2013, and 272 in 2016-2017. The proportion of patients with BP at the recommended goal was 49.2% in 1997-98, 44.5% in 1999-2000, 44.7% in 2006-07, 51.1% in 2011-13, and 58.8% in 2016-17 (p < 0.001). Mean systolic and diastolic BP decreased significantly independent of age, sex, and education (systolic BP: 137.9 ± 21.4 mmHg in 1997-98, 139.5 ± 21.6 mmHg in 1999-2000, 136.1 ± 20.3 mmHg in 2006-07, 134.8 ± 22.0 mmHg in 2011-13, and 134.2 ± 18.6 mmHg in 2016-17, p < 0.001; diastolic BP: 83.4 ± 11.0 mmHg in 1997-98, 84.8 ± 12.0 mmHg in 1999-2000, 85.2 ± 11.0 mmHg in 2006-07, 80.9 ± 12.5 mmHg in 2011-13, and 81.1 ± 10.4 mmHg in 2016-17; p < 0.001). Conclusion: The analysis of five multicenter surveys provides evidence of a decrease in BP in patients with established CAD over two decades. This trend is independent of age, sex, and the education level of the patients.

Recollection of Physician Information about Risk Factor and Lifestyle Changes in Chronic Coronary Syndrome Patients.

A patient's compliance to a physician's lifestyle information is essential in chronic coronary syndrome (CCS) patients. We assessed potential characteristics associated with a patient's recollection of physician information and lifestyle changes. This study recruited and interviewed patients (aged ≤ 80 years) 6-18 months after hospitalization due to acute coronary syndrome or elective myocardial revascularization. A physician's information on risk factors was recognized if patients recollected the assessment of their diet, weight management, blood pressure control, cholesterol level, diabetes, and other lifestyle factors by the doctor. Of a total of 946 chronic coronary syndrome patients, 52.9% (501) of them declared the recollection of providing information on more than 80% of the risk factors. A good recollection of risk factor information was associated with the following: a patient's age (OR per year: 0.97; 95% CI: 0.95 to 0.99), obesity (OR: 4.41; 95% CI: 3.09-6.30), diabetes (OR: 4.16; 95% CI: 2.96-5.84), diuretic therapy (OR: 1.41; 95% CI: 1.03-1.91), calcium channel blockers (OR: 1.47; 95% CI: 1.04-2.09), and ACEI/sartan (OR: 0.65; 95% CI: 0.45-0.94) at hospitalization discharge. In terms of goal attainment, better adherence to antihypertensive drugs (OR: 1.80; 95% CI: 1.07-3.03) was observed in the patients with a good compared to a poor recollection of risk factor information. The recollection of physician risk factor information was significantly associated with more comorbidities. Strategies to tailor the conveying of information to a patient's perception are needed for optimal patient-doctor communication.

Secondary prevention of coronary heart disease in Poland: does sex matter? Results from the POLASPIRE survey.

INTRODUCTION: Adherence to health­promoting behaviors intended to mitigate modifiable risk factors plays an important role in secondary cardiovascular prevention. OBJECTIVES: We aimed to evaluate sex differences in the prevalence and control of risk factors in patients with coronary heart disease (CHD). PATIENTS AND METHODS: The study included 1236 patients who experienced acute coronary syndrome or coronary revascularization within the last 6 to 24 months. Definitions of risk factors and treatment goals were based on the 2016 European Society of Cardiology guidelines on cardiovascular prevention. RESULTS: The prevalence of modifiable risk factors in both sexes was high, and their control inadequate. Women were older (P <0.001) and had a higher accumulation of multiple cardiovascular risk factors than men (P = 0.036). They more frequently had central obesity (P <0.001) and reduced values of glomerular filtration rate (P <0.001). Women more often experienced anxiety (P <0.001), reported lower levels of education (P <0.001) and lower income (P = 0.001), and those in the youngest age group were more likely to be exposed to second­hand smoking (P = 0.01). A large fraction of the study patients, men and women alike, did not meet the recommended therapeutic goals. For both sexes, participation in cardiac rehabilitation programs was associated with more frequent attainment of the recommended level of physical activity (P = 0.046) and smoking cessation (P = 0.01). CONCLUSIONS: The prevalence of cardiovascular risk factors in patients with CHD is high, especially in women. Therapeutic goals are met infrequently in both sexes. This situation calls for widening the access to educational programs and paying greater attention to their proper implementation.

Management of Dyslipidemia in Women and Men with Coronary Heart Disease: Results from POLASPIRE Study.

Cardiovascular diseases (CVDs) are the leading cause of death in Poland. Starting from 1992, a gradual decrease in mortality due to CVDs has been observed, which is less noticeable in women. Following this notion, we assessed sex differences in the implementation of ESC recommendations regarding lipid control and the use of statins as part of secondary CVDs prevention in 1236 patients with acute coronary syndrome or elective coronary revascularization within the last 6-24 months. During hospitalization women had more frequently abnormal TC levels than men (p = 0.035), with overall higher TC levels (p = 0.009) and lower HDL-C levels (p = 0.035). In the oldest group, they also had more frequently elevated LDL-C levels (p = 0.033). Similar relationships were found during the follow-up visit. In addition, women less often achieved the secondary lipid therapeutic goal for non-HDL-C (p = 0.009). At discharge from hospital women were less frequently prescribed statins (p = 0.001), which included high-intensity statins (p = 0.002). At the follow-up visit the use of high-intensity statins was still less frequent in women (p = 0.02). We conclude that women generally have less optimal lipid profiles than men and are less likely to receive high-intensity statins. There is a need for more organized care focused on the management of risk factors.

Undiagnosed Diabetes and Prediabetes in Patients with Chronic Coronary Syndromes-An Alarming Public Health Issue.

Dysglycemia is a public health challenge for the coming decades, especially in patients with chronic coronary syndromes (CCS). We want to assess the prevalence of undiagnosed diabetes mellitus (DM) and prediabetes, as well as identify factors associated with the development of dysglycaemia in patients with CCS. In total, 1233 study participants (mean age 69 ± 9 years), who, between 6 and 18 months earlier were hospitalized for acute coronary syndrome or elective revascularization, were examined (71.4% men). The diagnosis of DM, impaired fasting glucose (IFG), impaired glucose tolerance (IGT) have been made according to World Health Organization (WHO) criteria. Based on the oral glucose tolerance test (OGTT) results, DM has been newly diagnosed in 28 (5.1%, mean age 69.9 ± 8.4 years) patients, 75% were male (n = 21). Prediabetes has been observed in 395 (72.3%) cases. IFG was found in 234 (42.9%) subjects, 161 (29.5%) individuals had IGT. According to multinomial logistic regression, body mass index (BMI) and high-density lipoprotein cholesterol (HDL-C) should be considered when assessing risk of development of dysglycaemia after discharge from the hospital. Among people with previously diagnosed DM, a significantly higher percentage were willing to change their lifestyles after the index event compared to other patients. Patients with chronic coronary syndromes suffer a very high frequency of dysglycaemia. Most patients with chronic coronary syndromes, especially those with high BMI or low HDL-C, should be considered for screening for dysglycemia using OGTT within the first year after hospitalization. A higher percentage of patients who were aware of their diabetic status changed their lifestyles, which added the benefit of timely diagnosis and treatment of diabetes.

Changes over time in the prevention of recurrent coronary artery disease in everyday practice.

INTRODUCTION: Patients with coronary artery disease (CAD) are at high risk of recurrent cardiovascular events, and risk factor control is crucial in this population. OBJECTIVES: The aim of the study was to compare the implementation of the European Society of Cardiology guidelines regarding prevention of recurrent CAD in 2011 to 2013 with 2016 to 2017. PATIENTS AND METHODS: The study included 5 hospitals with cardiology departments serving the city of Kraków and its surrounding districts. Consecutive patients with established CAD were interviewed 6 to 18 months after hospitalization in the years 2011 to 2013 and 2016 to 2017. RESULTS: We examined 616 patients in 2011 to 2013 and 388 in 2016 to 2017 (mean [SD] age, 64.7 [8.8] years vs 66.4 [8.4] years; P <0.01). After adjusting for covariates, the proportion of patients with high blood pressure decreased by 8.9% (95% CI, -15.6% to -2.1%) and the proportion of patients with high level of low­ density lipoprotein cholesterol declined by 9.5% (95% CI, -16.7% to -2.2%) in 2016 to 2017 compared with 2011 to 2013, whereas the proportion of smoking patients (-0.2% [95% CI, -6% to 5.5%]) and those with high glucose levels (3.9% [95% CI, -2.2% to 10%]) and a body mass index of 25 kg/m2 or greater (3.8% [95% CI, -3.9% to 11.6%]) did not change. More patients were prescribed antiplatelets, ß­ blockers, angiotensin converting enzyme inhibitors or angiotensin II receptor blockers, calcium antagonists, and anticoagulants in the second period. CONCLUSIONS: We observed an increase in the proportion of patients with CAD who were prescribed cardiovascular drugs, and consequently a slight improvement in the control of their blood pressure and low­ density lipoprotein cholesterol. No changes were found regarding other main risk factors.

Effects of cardiac rehabilitation on risk factor management and quality of life in patients with ischemic heart disease: a multicenter cross­sectional study.

INTRODUCTION: While cardiac rehabilitation (CR) improves survival outcomes in patients with ischemic heart disease (IHD), the long­ term benefits of short term programs are still discussed. OBJECTIVES: The aim of the study was to assess the impact of CR on risk factor management in a multicenter real­ life registry of patients with IHD. PATIENTS AND METHODS: We included patients aged 80 years or younger who had been hospitalized due to acute coronary syndrome or for a myocardial revascularization procedure and interviewed 6 to 18 months later. Control of risk factors was compared between patients who participated in CR and those who did not. Propensity score matching was used to account for differences in patient characteristics between the groups. RESULTS: Of 1012 interviewed patients (28.6% women), 35.6% were referred for CR and 76.1% of them completed the program. Those referred were younger (P <0.001), employed (P <0.001), have presented with ST­ segment elevation myocardial infarction (P <0.001), had hypertension (P <0.001), and were current smokers (P <0.001). Logistics regression revealed that patients who participated in CR were more likely to stop smoking (odds ratio [OR], 2.42; 95% CI, 1.33-4.14), achieve acceptable glucose control (OR, 1.70; 95% CI, 1.02-2.83), and better quality of life (ß = 0.12; 95% CI, 0.00-0.24) compared with those who did not participate in CR. CONCLUSIONS: Cardiac rehabilitation is moderately effective if performed only once and without a continuous support program. Further efforts to increase referrals for CR in patients with IHD must be accompanied by a long­ term strategy to sustain the beneficial effects.

Smoking cessation in patients with established coronary artery disease: data from the POLASPIRE survey.

BACKGROUND: Smoking cessation in patients with coronary artery disease (CAD) is related to decreased risk of cardiovascular events. AIMS: To evaluate factors related to persistent smoking in patients with established coronary artery disease. METHODS: Patients aged 80 years or younger and hospitalized for acute coronary syndrome or a myocardial revascularization procedure were interviewed 6 to 18 months after the recruiting event. Medical history, smoking behavior, and exposure to environmental smoke were assessed during the interview. Self--reported smoking status was validated by carbon monoxide in exhaled air measurement. Persistent smoking was defined as smoking at the time of interview among those who smoked during the month prior to the recruiting event. RESULTS: We analyzed the data of 1034 patients, including 764 (73.9%) who reported smoking at any time in the past and 296 (28.6%) who smoked within 1 month before the recruiting hospitalization. At the time of the interview, the overall smoking rate was 17.2%, whereas 54.7% of patients were persistent smokers. Secondhand smoke exposure and duration of smoking were associated with lower likelihood whereas older age, high socioeconomic status, cardiac rehabilitation following a cardiovascular event, and consultation with a cardiologist were associated with higher likelihood of smoking cessation. CONCLUSIONS: Over half of all smokers hospitalized for CAD are still smoking 6 to 18 months after discharge. Older age, secondhand smoking, low socioeconomic status, lack of consultation with a cardiologist, and cardiac rehabilitation following hospitalization were related to persistent smoking. Our findings may help develop strategies aimed at assisting smoking cessation in patients with CAD.

Factors determining acceptance of illness in patients with arterial hypertension and comorbidities.

BACKGROUND: Hypertension is one of the most common chronic diseases. The need to undergo indefinite treatment combined with the risk of complications affecting the cardiovascular system impose significant psychological and somatic burden on the patient. Arterial hypertension (AH) is rarely an isolated disease and the most commonly observed comorbidities include metabolic disorders as well as clinically apparent complications associated with polypharmacy, which increases the risk of drug­induced adverse events. AIMS: The aim of the study was to determine factors that have an impact on illness acceptance in patients with AH. METHODS: The study included 532 patients diagnosed with AH. A standardized Acceptance of Illness Scale questionnaire and a questionnaire prepared by the authors were used. The Acceptance of Illness Scale allows to classify the illness acceptance as high (30-40 points), average (19-29 points), or low (8-18 points). RESULTS: A high level of illness acceptance was noted in 45% of participants and an average level in 46%. Patients with different levels of illness acceptance showed disparities in: duration of AH, number of cardiovascular and all diseases, frequency of mental disorders, and number of drugs taken. The number of cardiovascular diseases was significantly lower in patients with high levels of illness acceptance than in those with poor acceptance. Disease duration in patients with a high level of illness acceptance was significantly shorter than in patients with average acceptance. CONCLUSIONS: The level of illness acceptance is correlated with disease duration, number of diseases, and number of medications taken.

Obesity in patients with established coronary artery disease over a 20-year period (1997-2017).

BACKGROUND: Body mass reduction in overweight and obese people so as to reduce blood pressure, low­density lipoprotein cholesterol level, and the risk of type 2 diabetes as well as to lower the risk of recurrent cardiovascular events is strongly recommended in current guidelines. OBJECTIVES: To evaluate changes in body mass index (BMI) and waist circumference in patients with established coronary artery disease over a 20­year period (1997-2017). PATIENTS AND METHODS: Consecutive patients younger than 71 years of age and hospitalized for acute coronary syndrome or myocardial revascularization procedures were recruited and interviewed 6 to 18 months after their discharge from hospital. Weight, height, and waist circumference were measured in 1997 to 1998, 1999 to 2000, 2006 to 2007, 2011 to 2013, and 2016 to 2017. The same 5 hospitals took part in the surveys each time. RESULTS: We examined 412 patients in 1997 to 1998 (survey 1), 427 in 1999 to 2000 (survey 2), 422 in 2006 to 2007 (survey 3), 462 in 2011 to 2013 (survey 4), and 272 in 2016 to 2017 (survey 5). The proportion of obese patients was 24.5% in survey 1, 27.2% in survey 2, 34.1% in survey 3, 35.9% in survey 4, and 40.4% in survey 5 (P <0.001). The proportion of patients with central obesity also increased significantly (32.5% in survey 1, 40.5% in survey 2, 51.4% in survey 3, 48.6% in survey 4, and 61.3% in survey 5; P <0.001). BMI increased significantly in men, but not in women, whereas the mean waist circumference increased in both sexes. BMI and waist circumference increased irrespective of age and education. CONCLUSIONS: The analysis of 5 multicenter surveys showed a gradual increase in BMI and waist circumference in patients with established coronary artery disease over the course of 2 decades.

Plasma renin activity, serum aldosterone concentration and selected organ damage indices in essential arterial hypertension.

INTRODUCTION: The aim of this study was to assess the relations between plasma renin activity (PRA), serum aldosterone concentration (ALDO) and selected asymptomatic organ damage (AOD) indices in mild primary arterial hypertension (AH). MATERIAL AND METHODS: We measured PRA, ALDO, and selected AOD indices (carotid-femoral pulse wave velocity (cfPWV), central aortic pulse pressure (cPP), estimated glomerular filtration rate (eGFR)) in 122 patients with untreated AH. RESULTS: Patients with high PRA (≥ 0.65 ng/ml/h) were characterized by lower plasma sodium and aldosterone to renin ratio (ARR), higher ALDO, but a similar level of AOD indices compared to patients with low PRA. cfPWV (p = 0.04) and cPP (p = 0.019) increased with ARR, while eGFR decreased with ALDO (p = 0.008). Only eGFR was independently correlated with ALDO. In subjects with simultaneously high PRA and ARR values, we found significantly higher cfPWV (p = 0.02) and cPP (p = 0.04) and lower eGFR (p = 0.02) than in those with high PRA but low ARR values. CONCLUSIONS: Assessment of the influence of the renin-angiotensin-aldosterone system (RAAS) on AOD should include the relationship between renin and aldosterone. The PRA itself has no predictive value for AOD. More advanced arterial stiffness and renal impairment are associated with increased PRA and ARR. The RAAS activity might be useful in AOD prediction and hypertension severity assessment.

Selected matrix metalloproteinases activity and hypertension-mediated organ damage in relation to uric acid serum level.

BACKGROUND: Atherosclerosis is as a systemic inflammatory disease associated with the activationof many mediators, including matrix metalloproteinases (MMPs), and may be amplified by abnormal high serum uric acid (UA) concentration (hyperuricemia, HU). The aim of the study was to determine the relationship between serum UA concentration and activity of MMPs and their correlation with the hypertension-mediated organ damage (HMOD) intensity. METHODS: One hundred and nine patients untreated with antihypertensive, hypolipemic or uratelowering drugs with diagnosed stage 1-2 essential hypertension were included in this study. In all participants blood pressure (BP) was measured, carotid-femoral pulse wave velocity (PWV), intima-media thickness (IMT), echocardiography and blood tests including UA, lipids and serum concentrations of MMPs (1, 2, 3, 9) were observed. The participants were divided into hyper- and normuricemic groups. RESULTS: Uric acid concentration in the whole study group positively correlated with some HMOD parameters (IMT, PWV, left ventricular mass index, left atrial dimension). Among the studied metalloproteinases only MMP-3 activity positively correlated with serum UA concentration independently of age, body mass index and serum lipids (R2 = 0.11, p = 0.048). Multivariate regression analysis showed positive association between IMT and BP, UA concentration and MMP-3 activity, independently of waist circumference and serum lipids (R2 = 0.328, p < 0.002). Patients with HU were characterized by higher activity of MMP-3 than those without (19.41 [14.45; 21.74] vs. 13.98 [9.52; 18.97] ng/mL, p = 0.016). CONCLUSIONS: The present results may support the thesis that UA and the increased by UA activity of MMPs may take part in the development of HMOD, especially IMT.

The relation of nocturnal exposure to aircraft noise and aircraft noise-induced insomnia with blood pressure.

INTRODUCTION: Nighttime environmental noise exposure leads to unconscious stress reactions and autonomic arousals. These may disturb overnight sleep and the diurnal blood pressure (BP) profile, contributing to an increased risk of developing hypertension. OBJECTIVES: This study aimed to investigate the effects of chronic nighttime exposure to aviation noise on sleep disturbances and the relationship with annoyance and the BP profile. PATIENTS AND METHODS: Based on acoustic maps, we selected 2 groups of normotensive participants: exposed (n = 48; mean age, 50.9 years; 29 women) and unexposed (n = 50; mean age, 49.7 years; 35 women) to nocturnal aircraft noise. We collected anthropometric and demographic data using a standardized questionnaire. Insomnia symptoms were evaluated using the Athens Insomnia Scale (AIS). In both study groups, we performed office BP measurements and 24­hour ambulatory BP monitoring. RESULTS: Noise­exposed participants showed distinctive sleep disturbances, higher AIS scores (4.3 vs 2.3; P = 0.01), and an increased insomnia risk (odds ratio, 2.62; P = 0.046). With increased noise annoyance, a higher AIS score was observed (PANOVA = 0.02). Noise­exposed individuals had higher diastolic BP at night than those unexposed (64.6 mm Hg vs 61.7 mm Hg; P = 0.03). Insomnia among noise­exposed participants resulted in higher 24­hour (115.2 mm Hg vs 122.2 mm Hg; P = 0.03) and nighttime (103.7 mm Hg vs 112.2 mm Hg; P = 0.02) systolic BP. A significant interaction was noted between aircraft noise exposure and the AIS score. The association of the AIS score with 24­hour systolic BP (P = 0.048) and pulse pressure (P = 0.04) was stronger in the exposed group. CONCLUSIONS: The study results may indicate different pathomechanisms affecting BP in terms of nighttime noise and noise­related insomnia.

Mortality in patients after acute myocardial infarction managed by cardiologists and primary care physicians: a systematic review.

INTRODUCTION: Mortality following acute myocardial infarction (AMI) remains high despite of progress in invasive and noninvasive treatments. OBJECTIVES: This study aimed to compare the outcomes of ambulatory treatment provided by cardiologists versus general practitioners (GPs) in post­AMI patients. PATIENTS AND METHODS: We conducted a systematic search in 3 electronic databases for interventional and observational studies that reported all­cause mortality, mortality from cardiovascular causes, stroke, and myocardial infarction at long­term follow­up following AMI. We assessed the risk of bias of the included studies using the Risk of Bias in Nonrandomized Studies of Interventions (ROBINS­I) tool. For randomized trials, we used the revised Cochrane risk of bias tool (RoB 2.0). RESULTS: Two nonrandomized studies fulfilled the inclusion criteria. We assessed these studies as having a moderate risk of bias. We did not pool the results owing to significant heterogeneity between the studies. Patients consulted by both a cardiologist and a GP were at lower risk of all­cause death as compared with patients consulted by a cardiologist only (risk ratio [RR], 0.92; 95% CI, 0.85-0.99). Patients consulted by a cardiologist with or without GP consultation were at lower risk of all­cause death compared with those consulted by a GP only in both studies (RR, 0.8; 95% CI, 0.75-0.85 and RR, 0.44; 95% CI, 0.41-0.47). CONCLUSIONS: Patients after AMI consulted by both a cardiologist and a GP may be at lower risk of death compared with patients consulted by a GP or a cardiologist only. However, these findings are based on moderate­quality nonrandomized studies. We found no evidence on the relation between the specialization of the physician and the risk of cardiovascular death, stroke, or myocardial infarction in AMI survivors.

Cardiovascular End Points and Mortality Are Not Closer Associated With Central Than Peripheral Pulsatile Blood Pressure Components.

Pulsatile blood pressure (BP) confers cardiovascular risk. Whether associations of cardiovascular end points are tighter for central systolic BP (cSBP) than peripheral systolic BP (pSBP) or central pulse pressure (cPP) than peripheral pulse pressure (pPP) is uncertain. Among 5608 participants (54.1% women; mean age, 54.2 years) enrolled in nine studies, median follow-up was 4.1 years. cSBP and cPP, estimated tonometrically from the radial waveform, averaged 123.7 and 42.5 mm Hg, and pSBP and pPP 134.1 and 53.9 mm Hg. The primary composite cardiovascular end point occurred in 255 participants (4.5%). Across fourths of the cPP distribution, rates increased exponentially (4.1, 5.0, 7.3, and 22.0 per 1000 person-years) with comparable estimates for cSBP, pSBP, and pPP. The multivariable-adjusted hazard ratios, expressing the risk per 1-SD increment in BP, were 1.50 (95% CI, 1.33-1.70) for cSBP, 1.36 (95% CI, 1.19-1.54) for cPP, 1.49 (95% CI, 1.33-1.67) for pSBP, and 1.34 (95% CI, 1.19-1.51) for pPP (P<0.001). Further adjustment of cSBP and cPP, respectively, for pSBP and pPP, and vice versa, removed the significance of all hazard ratios. Adding cSBP, cPP, pSBP, pPP to a base model including covariables increased the model fit (P<0.001) with generalized R2 increments ranging from 0.37% to 0.74% but adding a second BP to a model including already one did not. Analyses of the secondary end points, including total mortality (204 deaths), coronary end points (109) and strokes (89), and various sensitivity analyses produced consistent results. In conclusion, associations of the primary and secondary end points with SBP and pulse pressure were not stronger if BP was measured centrally compared with peripherally.

Secondary prevention of coronary artery disease in Poland. Results from the POLASPIRE survey.

BACKGROUND: The highest priority in preventive cardiology is given to patients with established coronary artery disease (CAD). The aim of the study was to assess the current implementation of the guidelines for secondary prevention in everyday clinical practice by evaluating control of the main risk factors and the cardioprotective medication prescription rates in patients following hospitalization for CAD. METHODS: Fourteen departments of cardiology participated in the study. Patients (aged ≤ 80 years) hospitalized due an acute coronary syndrome or for a myocardial revascularization procedure were recruited and interviewed 6-18 months after the hospitalization. RESULTS: Overall, 947 patients were examined 6-18 months after hospitalization. The proportion of patients with high blood pressure (≥ 140/90 mmHg) was 42%, with high low-density lipoprotein cholesterol (LDL-C ≥ 1.8 mmol/L) 62%, and with high fasting glucose (≥ 7.0 mmol/L) 22%, 17% of participants were smokers and 42% were obese. The proportion of patients taking an antiplatelet agent 6-18 months after hospitalization was 93%, beta-blocker 89%, angiotensin converting enzyme inhibitor or sartan 86%, and a lipid-lowering drug 90%. Only 2.3% patients had controlled all the five main risk factors well (non-smoking, blood pressure < 140/90 mmHg, LDL-C < 1.8 mmol/L and glucose < 7.0 mmol/L, body mass index < 25 kg/m2), while 17.9% had 1 out of 5, 40.9% had 2 out of 5, and 29% had 3 out of 5 risk factors uncontrolled. CONCLUSIONS: The documented multicenter survey provides evidence that there is considerable potential for further reductions of cardiovascular risk in CAD patients in Poland. A revision of the state funded cardiac prevention programs seems rational.
