Could We Predict POAF With a Simple Ambulatory Oscillometry Evaluating Aortic Stiffness?

OBJECTIVE: To investigate the relationship between aortic stiffness and postoperative atrial fibrillation (POAF) in patients undergoing coronary artery bypass grafting (CABG). METHODS: This study included 110 patients undergoing elective isolated CABG. Aortic stiffness was measured using a noninvasive oscillometric sphygmomanometer before surgery. Characteristics of patients with and without POAF were compared. RESULTS: POAF developed in 32 (29.1%) patients. Patients with POAF were older (63.7±8.6 vs. 58.3±8.4; P=0.014). Chronic obstructive pulmonary disease (COPD) was more common in patients with POAF (11.5% vs. 37.5%; P=0.024), whereas the frequency of hypertension, diabetes mellitus, smoking, and previous coronary artery disease did not differ. C-reactive protein and cholesterol levels were similar between patients with and without POAF. Left atrial diameter was greater in patients with POAF (35.9±1.6 vs. 36.7±1.7; P<0.039). Peripheral (p) and central (c) systolic and diastolic blood pressures were also similar between the groups, whereas both p and c pulse pressures (PP) were greater in patients with POAF (pPP: 44.3±11.9 vs. 50.3±11.6; P=0.018, cPP: 31.4±8.1 vs. 36.2±8.9; P=0.008). Pulse wave velocity (PWV) was significantly higher in POAF (8.6+1.3 vs. 9.4+1.3; P=0.006). PWV, pPR and COPD were independent predictors of POAF in multivariate regression analysis. In receiver operating characteristic analysis, PWV and pPP have similar accuracy for predicting POAF (PWV, area under the curve [AUC]: 0.661, 95% confidence interval [CI] [0.547-0.775], P=0.009) (pPP, AUC: 0.656, 95% CI [0.542-0.769], P=0.012). CONCLUSION: COPD, PWV, and PP are predictors of POAF. PP and PWV, easily measured in office conditions, might be useful for detecting patients with a higher risk of POAF.

Analysis of Coronary Angiography and Revascularization Rates Made Over 5 Years in Public Institutions in Türkiye.

BACKGROUND: Coronary angiography is currently the gold standard anatomic imaging method used to diagnose obstructive epicardial coronary artery disease. In patients with critical coronary stenosis, surgical or percutaneous revascularization is provided. Normal coronary artery ratio in coronary angiography is an indirect indicator of patient selection quality. The aim of our study is to evaluate the efficiency of coronary angiography by examining the revascularization rates according to years in patients who underwent coronary angiography. METHODS: Revascularization rates will be determined by analyzing retrospectively the number of patients who underwent coronary angiography in our country between 2016 and 2021 and were revascularized interventionally or surgically. The number of patients who underwent percutaneous, surgical, and total revascularization were proportioned to the number of coronary angiography, and their percentages were determined. RESULTS: From 2016 to 2019, there was a continuous increase in the number of coronary angiography. In 2020, the lowest coronary angiography numbers (n = 222.159) of the last 6 years were seen with the effect of the COVID-19 pandemic. In 2021, it was observed that the number of coronary angiography increased again with the relaxation of pandemic measures and the approaching of hospital admissions to old levels. It is seen that revascularization is performed in up to one-third of the patients who underwent coronary angiography. CONCLUSION: Similar to the rest of the world, revascularization rates as a result of coronary angiography procedures performed in our country are low. With this result, it should not be concluded that coronary angiography is not used effectively; on the contrary, the efficiency of coronary angiography can be increased by more effective use of noninvasive tests.

Coronary sinus collapsibility index and inferior vena cava collapsibility index can predict right atrial pressure in patients undergoing right heart catheterization.

BACKGROUND: The aim of the study is to investigate the relationship between the diameters and collapsibility indices of coronary sinus (CS) and inferior vena cava (IVC) and invasively measured right atrial pressure (RAP), and to determine whether these parameters have predictive value on RAP. METHODS: A total of 136 patients undergoing right heart catheterization due to pulmonary arterial hypertension were included in the study prospectively. CS diameters, IVC diameters, CS collapsibility index (CSCI), and IVC collapsibility index (IVCCI) were measured by echocardiography before catheterization. Pearson correlation analysis was used to compare the parameters. Receiver operating characteristics (ROC) curve analysis was used to determine the predictive value of the CS and IVC collapsibility indices in predicting RAP. RESULTS: Patients were divided into two groups as invasively measured RAP≥10 mm Hg (n:57) and RAP < 10 mm Hg (n:79). In the group with RAP≥10 mm Hg, IVC and CS diameters were higher than in the group with RAP < 10 mm Hg, while the IVCCI and CSCI were lower (p < 0.001). A negative correlation was observed between CSCI and IVCCI and RAP. Also, a positive correlation was observed between CSCI and IVCCI. Optimal cut-off value for IVCCI was 46.1 with a sensitivity of 75%, and specificity of 79.7%. Optimal cut-off value for CSCI was 39.2 with a sensitivity of 75.4%, and specificity of 88.6%. CONCLUSION: CS and IVC diameters and collapsibility indices measured by echocardiography were found to be associated with invasively measured RAP, and may be used together for estimating RAP.

Prognostic Value of the Residual SYNTAX Score on In-Hospital and Follow-Up Clinical Outcomes in ST Elevation Myocardial Infarction Patients Undergoing Percutaneous Coronary Interventions.

AIMS: We investigated the prognostic significance of residual SYNTAX score (RSS) in patients undergoing PCI due to STEMI and relationship between RSS and in-hospital and long-term ischemic cardiac events. METHODS: Between June 2015 and December 2018, 538 patients who underwent primary PCI were evaluated for in-hospital events and 478 patients were evaluated for clinical events during follow-up. Primary and secondary endpoints for both in-hospital and follow-up periods were cardiac death and major adverse cardiac events (MACE). RESULTS: 538 patients were included the study. RSS values of 131 patients were 0, and RSS values of 407 patients were >0. The median value of the RSS > 0 group was 7. According to this value, the RSS > 0 group was divided into 2 groups as R-ICR (RSS < 7, N = 188) and ICR (RSS ≥ 7, n = 219). In the RSS ≥ 7 group, during in-hospital and follow-up period, both mortality and MACE rates were higher than the other two groups. Area under the curve (AUC) for RSS for in-hospital death was found to be higher than SS (p=0.035) but similar to Grace Score (GS) (p=0.651). For MACE, RSS was higher than SS (p=0.025) and higher than the GS (p=0.041). For follow-up cardiac mortality, the AUC of the RSS was found to be higher than SS (0.870/0.763, p=0.02) and GS (0.870/0.733, p=0.001). For MACE, the AUC of RSS was higher than SS (p=0.03) and GS (p=0.004). CONCLUSIONS: High RSS values in STEMI patients are associated with increased risk of ischemic cardiac events. RSS may help determine revascularization and level of additional PCI to improve prognosis by reducing the risk of ischemic cardiac events after P-PCI.

ST segment elevation myocardial infarction (STEMI) patients are more likely to achieve lipid-lowering treatment goals: A retrospective analysis of patients presenting with first acute coronary syndromes.

Statin nonadherence or discontinuation is associated with increased cardiovascular events. Many factors related to the physicians or the patients are influential in this. We aimed to compare the compliance with statin therapy between the patients who first presented with ST-elevation myocardial infarction (STEMI), non-ST-elevation myocardial infarction (NSTEMI), and unstable angina pectoris (UA) based on the target achievement according to the current dyslipidemia guidelines.We retrospectively acquired all the information about demographic characteristics, in-hospital revascularization procedures, prescribed treatments, and index and up to 6-month follow-up laboratory results of the first acute coronary syndrome patients. Acute coronary syndrome patients were divided into 3 groups as STEMI, NSTEMI, and UA.The STEMI group consisted of 260 patients, NSTEMI group consisted of 560 patients, and UA group consisted of 206 patients. Seventy-six percent of patients underwent percutaneous coronary interventions, 18.3% were managed medically, and 5.7% were referred for coronary artery bypass grafting. There was a significant decrease in low-density lipoprotein-cholesterol (LDL-C) values with the statin treatment at the follow-up in all 3 groups (for all P < .001). In the STEMI group, the percentage of those achieving the target LDL-C level was significantly higher than those who did not achieve the target according to both The American College of Cardiology/American Heart Association (ACC/AHA) and European Society of Cardiology dyslipidemia guidelines. The LDL-C target achievement rates were also higher in the STEMI group than in the NSTEMI and UA groups.Our study concluded that statin treatment goals were more attained in STEMI patients than NSTEMI and UA. All physicians should encourage lifelong intensive statin treatment in UA and NSTEMI patients such as STEMI patients.

Evaluation of atrial electromechanical functions in dipper and nondipper hypertension patients using left atrial strain P-wave dispersion and P terminal force.

OBJECTIVE: Nondippers are known to carry a high risk of cardiovascular morbidity and mortality. The aim of this study was to investigate the effects of dipper and nondipper status of hypertension on left atrial (LA) systolic and diastolic functions using two-dimensional speckle tracking echocardiography (2D-STE), P-wave dispersion (PWD), and P terminal force (PTF) in hypertensive patients. METHODS: A total of 72 patients and 39 healthy individuals were included in the study. The patients were classified as nondippers if their daytime ambulatory systolic and diastolic blood pressure did not decrease by at least 10% during the night. Atrial electromechanical delay times, LA strain values were obtained by 2D-STE with automated software and compared between the groups. PWD and PTF data were calculated on the electrocardiography. RESULTS: Inter-atrial (dippers: 25.5 ± 3.9, nondippers: 32.2 ± 7.4, P < .001), left-atrial (dippers: 14.9 ± 3.7, nondippers: 18.2 ± 6.0, P = .016), and right atrial (dippers: 10.5 ± 2.1, nondippers: 14.2 ± 5.2, P < .001) electromechanical delay times were significantly longer in nondippers. LA strain S (dippers: 34.2 [29.7-38.7], nondippers: 27.7 [22.7-32.2], P < .001), LA strain E (dippers: 18.2 [16.6-20.1], nondippers: 14.4 [11.6-16.8], P < .001), and LA strain A (dippers: 15.8 [13.5-17.9], nondippers: 12.7 [9.9-14.5], P < .001) were significantly lower in nondippers. Nondippers also had an increased values of maximum P-wave duration (dippers: 0.117 [0.10-0.12], nondippers: 0.126 [0.12-0.14], P < .001), PWD (dippers: 0.062 [0.06-0.07], nondippers: 0.069 [0.06-0.08], P = .004), and PTF (dippers: 0.055 ± 0.02, nondippers: 0.066 ± 0.02, P = .02). CONCLUSION: Nondipping pattern in hypertensive patients had a worse cardiac remodeling, and impaired mechanical LA function compared with dipping pattern. The PWD and PTF findings support these changes.

[Polypharmacy and drug interactions in elderly patients]. / Yasli hastalarda polifarmasi ve ilaç etkilesimi.

Although the definition of polypharmacy is not yet clear today, it is generally regarded as drug use more than the patient needs. Advanced age is the most important risk factor for polypharmacy. In addition, other risk factors are loss of current cognitive functions, low socioeconomic level and nursing care. It is seen in about 40% of people over 75 years of age worldwide, varying between countries of extreme poverty. Incorrect drug use, drug side effects and drug-drug interaction lead to unwanted hospitalizations. In particular, cardiovascular drugs pose risks in terms of drug side effects in advanced ages. Altering the pharmacokinetics and pharmacodynamics of the drug along with advanced age lead to more frequent side effects or no effect of the drugs. The most important point to prevent polypharmacy is to inform the patient or the patient's caregiver fully and to target treatment with a minimum number of drugs and doses.

[Dyslipidaemias in elderly patients]. / Yasli hastalarda dislipidemi.

Statin use in people over 65 years of age is high. A meta-analysis of older patients included in randomised trials found good evidence that statins reduce vascular events and mortality in people with existing coronary heart disease. In older adults, exposure to higher doses of statins or higher potency statins does not increase their effectiveness, but does increase the risk of adverse effects such as myopathy and cognitive impairment. Increasing age is a risk factor for adverse events with statins. Older patients may be less resilient to these effects. Older patients may have more comorbidities and be taking more concomitant drugs than the study populations in statin trials. Applying the evidence for statins to older individuals therefore requires frequent review and consideration of the therapeutic goals and potential benefits and harms.

Evaluation of arterial stiffness and subclinical atherosclerosis in patients with Behçet's disease without cardiovascular involvement.

OBJECTIVE: This study was conducted to evaluate arterial structure and function with assessment of pulse wave velocity (PWV) and carotid intima-media thickness (CIMT) in patients with Behçet's disease (BD). METHODS: Thirty patients (13 female, 17 male) with BD and 30 age, sex-matched healthy controls (12 female, 18 male) with no known cardiovascular disease were enrolled in this study. Carotid-femoral PWV and CIMT were measured. RESULTS: PWV was higher in BD patients compared with control group (6.35±1.05 vs. 5.75±0.83, respectively; p=0.017). There was no significant difference in maximum CIMT (0.751±0.077 mm vs. 0.735±0.079 mm, respectively; p=0.435), or mean CIMT (0.643±0.070 mm vs. 0.629±0.069, respectively; p=0.452). Maximum CIMT, mean CIMT, and PWV were positively correlated with duration of disease (r=0.410, p=0.025; r=0.404, p=0.027; and r=0.362, p=0.049, respectively). CONCLUSION: Findings suggest that endothelial function is impaired in cases of BD before visible structural changes to arterial wall. PWV is more useful measurement than CIMT in determination of vascular damage in BD, especially in early stage of disease duration.
