ABSTRACT
BACKGROUND: Critical limb ischemia (CLI) patients take too many medications because they are elderly and frail patients with multiple comorbidities. Polypharmacy is associated with frailty, although its prognostic significance in CLI patients is unknown. In this study, we aimed to determine the prevalence of hyperpolypharmacy among adults with CLI and its effect on 1-year amputation and mortality. METHODS: A total of 200 patients with CLI who underwent endovascular therapy (EVT) for below-knee (CTC) lesions were included in this study. Hyperpolypharmacy was defined as using ≥10 drugs. Patients were divided into two groups according to the presence of hyperpolypharmacy. RESULTS: We detected hyperpolypharmacy in 66 patients. The incidence of 1-year amputation [24 (36.4) versus 12 (9), p<.001] and mortality [28 (42.4) versus 12 (9), p<.001] were higher in patients with hyperpolypharmacy. Univariate and multivariate cox regression analyses were used to determine the independent predictors of amputation and mortality. In the receiver operating characteristic curve analysis, the cut-off value was defined as 10 or more drug use was able to detect the presence of 1-year mortality with 67.5% sensitivity and 79.4% specificity. The Kaplan-Meier method showed a significant difference (rank p <.001 between log groups), and hyperpolypharmacy was associated with 1-year amputation and mortality. CONCLUSION: Hyperpolypharmacy was significantly associated with 1-year mortality and major amputation in CLI patients. Hyperpolypharmacy can be a valuable aid in patient risk assessment in the CLI.
ABSTRACT
Objective: In this study, we investigated the occurrence of no-reflow (NR) in percutaneous coronary intervention (PCI) for saphenous vein grafts (SVGs) and its relationship with a new systemic immune-inflammation index (SII) that determines inflammation. Methods: We studied 303 patients with acute coronary syndrome without ST elevation who underwent PCI for SVG disease. Results: NR formation during SVG PCI was significantly higher in patients with high SII (p < 0.001). NR occurrence was 12.8% when SII was ≤548 and 41.9% when SII was >548. Conclusion: Our study is the first to investigate SII as the state of inflammation and its effect on the SVG PCI. Patients with higher SII have a higher risk of NR during an SVG for PCI.
This study is about a type of surgery called bypass surgery, which is done to help when the heart is not working properly. During this surgery, doctors sometimes use veins in the leg to create new pathways for blood to flow around the heart. However, after a while these vessels can narrow or become blocked, so another procedure, stenting, is done to open them. Even after the stent is placed, the blood flow through the vein is sometimes not as good as it should be. This is called 'no reflow'. We wanted to investigate how often this problem occurs and whether it is related to a marker called the systemic immune-inflammation index (SII), which is a measure of inflammation in the body. We analyzed 303 patients who underwent stenting after a heart attack. We divided them into two groups according to their SII scores and investigated whether there was a difference in no-reflow occurrence between the two groups. We found that patients with a higher SII score were more likely to have no reflow during the stenting procedure, and an increased risk of no reflow if the SII score was above 548. This study was the first to look at SII and how it affects the stenting procedure for vessels used in bypass surgery.

OBJECTIVE: Critical limb ischemia (CLI) is a progressive form of peripheral artery disease (PAD). Patients with CLI have poor long-term prognosis. The aim of this study was to investigate the value of sarcopenia in terms of 1-year mortality in patients with below-the-knee lesions who underwent endovascular treatment for CLI. METHODS: A total of 190 patients with critical limb ischemia who underwent endovascular treatment (EVT) for below-the-knee (BTK) lesions were enrolled in this study. Sarcopenia was defined using the psoas muscle index (PMI). PMI was obtained by calculating the average psoas muscle area (APMA) of the left and right psoas muscles at the third lumbar vertebra level and dividing by the square of the height (cm2/m2). The primary endpoint of the study was 1-year mortality and the secondary endpoint was 1-year amputation. Patients were divided into 2 groups according to presence of sarcopenia. RESULTS: We detected sarcopenia in 64 patients. The mean age, height, and EF were higher in sarcopenia group. The psoas muscle area, weight, psoas muscle index, body-mass index, albumin level, and GFR were lower in sarcopenia group. The incidence of amputation (11.9% vs 29.7%, p = 0.003) and mortality (15.1% vs 35.9%, p = 0.001) were higher in patients with sarcopenia. Univariate and multivariate logistic regression analyses were used to determine the independent predictors of amputation and mortality. The survival curve for 1-year using the sarcopenia was analyzed using the Kaplan-Meier method, and statistical analysis was performed with the log-rank test. The presence of sarcopenia, glomerular filtration rate level, and low ejection fraction were found to be independent predictors of mortality. CONCLUSIONS: Sarcopenia was associated with 1-year mortality in patients with CLI undergoing EVT for BTK lesions. Also, patients with sacropenia had higher 1-year amputation rates. Sarcopenia may be a simple method to help patient selection, assessment, and intervention strategy for EVT and may improve patient outcomes.

BACKGROUND: Red cell distribution width (RDW) and the systemic immune-inflammation index (SII) have been extensively studied as predictors of morbidity and mortality in several cardiovascular diseases. This prospective study aimed to investigate the relationship between long term major adverse cardiac events (MACEs) and simple hematological parameters in hypertensive patients. METHODS: The study included a total of 1202 patients with newly diagnosed HT. Of the patients, 662 (55.1%) were female and 540 (44.9%) were male, with a mean age of 53.0 ± 11.4 years. The primary endpoint of the study was long term MACE, including cardiac death, stroke, and myocardial infarction. This is the first study focusing on the association of SII with major adverse cardiovascular outcomes in patients with HT. RESULTS: Eighty-nine patients (8.7%) developed at least one MACE during a mean follow-up period of 82.2 ± 1.3 months. RDW (13.0 ± 0.9 vs. 13.5 ± 1.2%, p < .001) and SII [465.0 (353.4-609.4) vs. 584.4 (468.9-794.0) x103/µL, p < .001] were significantly higher in patients with MACEs. The prevalence of MACEs was significantly higher in patients with RDW>13.1% (10.4 vs. 5%; p < .001) and in patients with SII>465 x103/µL (11.8 vs. 3.1%; p < .001). The multivariate logistic regression analysis showed SII and RDW were independent predictors of MACEs. CONCLUSION: The results of the study demonstrated that the RDW and SII were independent predictors of long-term cardiovascular events in hypertensive patients. These simple hematological parameters may be used as prognosticators of MACE in patients with newly diagnosed HT.

OBJECTIVES: Thrombotic process is triggered in the course of Coronavirus disease-2019 (COVID-19), which is a global pandemic, and both arterial and venous systems are affected. ST-elevation myocardial infarction (STEMI) that may develop in these patients may cause more complicated results with the effect of thrombosis burden. Our aim in this study is to determine the frequency of no-reflow phenomenon in COVID-19 patients with STEMI and to determine the factors that predict this complication. METHODS: In this study, which is a single-centre, retrospective and observational, a total of 126 patients who underwent primary percutaneous coronary intervention (pPCI) in our centre due to STEMI between 11 March 2020 and 10 January 2021 were evaluated. Patients were divided into two groups according to the presence of COVID-19 infection. RESULTS: While 62 patients were in the COVID-19 (+) group, 64 patients were evaluated in the COVID-19 (-) group. When the two groups are compared, C-reactive protein, D-dimer, ferritin and neutrophil-lymphocyte ratio (NLR) were significantly higher, and the lymphocyte count was significantly lower in the COVID-19 (+) group. No-reflow was numerically higher in patients with COVID-19. In multivariable analysis, D-dimer and NLR were found to be independent predictors of no-reflow phenomenon in COVID-19 patients. CONCLUSIONS: Although the no-reflow phenomenon was numerically higher in COVID-19 patients who underwent pPCI due to STEMI compared to the non-COVID group, no statistical difference was found in our study. However, NLR and D-dimer have been identified as independent predictors of no-reflow development risk in COVID-19 patients.

BACKGROUND: Chronic limb-threatening ischemia (CLTI), which presents with ischemic rest pain, ulceration, or gangrene, is a complex form of peripheral artery disease that can cause mortality and amputation. C-reactive protein (CRP), an inflammatory marker, indicates vascular inflammation resulting from the cytokine-dependent inflammatory process in the arterial wall, and arterial atherosclerosis resulting from the inflammation. Lower albumin levels are also associated with peripheral artery disease. We investigated the association between CRP/Albumin ratio (CAR) and long-term mortality in patients with CLTI. METHODS: A total of 172 patients who underwent endovascular treatment (EVT) for below the knee (BTK) lesions were enrolled in this study. Patients with acute infection requiring antibiotic therapy, chronic inflammatory disease, end-stage liver disease, malignancy were excluded from the study. Besides, patients with pre-follow-up intervention to the same vascular bed were also excluded from the study. The primary endpoint of the study was all-cause mortality. Patients were divided into 2 groups according to mortality. RESULTS: A total of 70 patients (40.6%) died during 32 ± 21 months of follow-up in the present study. The major amputation rate was 21.5%. The mortality (+) group was older and had higher rates of congestive heart failure, chronic kidney disease, history of stroke, and CRP levels. Moreover, statin and ACE inhibitor/angiotensin receptor blocker (ACE/ARB) use, GFR, and albumin levels were lower in the mortality (+) group. CAR was significantly higher in the mortality (+) group when comparing both groups (3.25 [1.46 - 7.86] vs. 9.75 [4.5 - 17.71], P < 0.001). CAR, congestive heart failure, chronic kidney disease, history of stroke, ACE/ARB, or statin use were independent predictors of all-cause mortality in multivariable Cox regression analysis. CONCLUSIONS: CAR was associated with mortality in CLTI patients undergoing EVT for BTK lesions. CAR may be a simple method to help patient selection, assessment, and intervention strategy for EVT and may improve patient outcomes.

BACKGROUND: Pulmonary arterial hypertension (PAH) is a severe, life-threatening disorder despite the availability of specific drug therapy. A lack of endogenous prostacyclin secondary to downregulation of prostacyclin synthase in PAH may contribute to vascular pathologies. Therefore, prostacyclin and its analogs including inhaled iloprost may decrease pulmonary arterial pressure and ventricular pressure. METHODS: Here, we studied that acute effects of iloprost used in pulmonary vasoreactivity testing on the intracardiac conduction system in patients with PAH. A total of 35 (15 idiopathic PAH, 20 congenital heart disease) patients with PAH were included in this prospective study. Patients were divided into two groups: 22 patients with negative pulmonary vasoreactivity in group 1 and 13 with positive pulmonary vasoreactivity in group 2. Electrophysiological parameters including basic cycle length, atrium-His (AH) interval, His-ventricle (HV) interval, PR interval, QT interval, QRS duration, Wenckebach period, and sinus node recovery time (SNRT) were evaluated before and after pulmonary vasoreactivity testing in both groups. RESULTS: The AH interval (81 [74-93]; 80 [65.5-88], pâ¯= 0.019) and SNRT (907.7⯱ 263.4; 854.0⯱ 288.04, pâ¯= 0.027) was significantly decreased after pulmonary vasoreactivity testing. Mean right atrium pressure was found to be correlated with baseline AH (râ¯= 0.371, pâ¯= 0.031) and SNRT (râ¯= 0.353, pâ¯= 0.037). CONCLUSION: Inhaled iloprost can improve cardiovascular performance in the presence of PAH, primarily through a reduction in right ventricular afterload and interventricular pressure. Decreased pressure on the interventricular septum and ventricles leads to conduction system normalization including of the AH interval and SNRT due to resolution of inflammation and edema.

BACKGROUND: P-wave duration and P-wave dispersion (PWD) give information about inhomogeneous and discontinuous atrial conduction, which are believed to be the leading electrophysiological causes of atrial fibrillation. The aim of this study was to investigate the effect of percutaneous chronic total occlusion (CTO) revascularization on P-wave duration and PWD in electrocardiography (ECG). MATERIALS AND METHODS: We enrolled 98 consecutive patients with sinus rhythm who underwent percutaneous coronary interventions (PCIs) for CTO. The maximum (Pmax) and minimum P-wave duration and PWD were measured before CTO interventions and at the first and sixth months after the procedure. RESULTS: There was no significant differences between the successful and failed CTO PCI groups in pre-procedural demographic, clinical, laboratory, angiographic data, and ECG parameters. Pmax values and PWD at 1 month and 6 months after successful CTO PCI were statistically lower than those at baseline (p < 0.001), while there was no significant change in the failed CTO PCI group. PWD values were significantly lower at 6 months of follow-up, regardless of the target vessel (p = 0.010, p < 0.001, p < 0.001; for left anterior descending, circumflex and right coronary artery, respectively). Compared to pre-CTO values in all Rentrop classes, PWD values were significantly lower at the sixth month. CONCLUSIONS: This study demonstrated that Pmax and PWD, which are risk factors for atrial arrhythmias, significantly reduced within 1 and 6 months after successful CTO PCI irrespective of the target vessel.
ABSTRACT
BACKGROUND: To test the hypothesis that making a diagnosis of left ventricular noncompaction (LVNC) on cardiac magnetic resonance imaging (CMRI) using a noncompacted-to-compacted (NC/C) myocardium ratio > 2.3 would yield significant errors, and also to test a diagnostic flowchart in patients who undergo CMRI and have clinical and echocardiographic findings suggesting LVNC could improve the diagnosis of LVNC. METHODS: A total of 84 patients with LVNC and 162 controls consisting of patients with other diseases and healthy participants who had CMRI and echocardiograms were selected. The diagnostic flowchart of the study involved the use of CMRI with all available sequences for patients with a high pre-test probability of LVNC. Two blinded independent cardiologists evaluated echocardiograms, and patients with suggestive echocardiographic and clinical findings for LVNC were enrolled in the high pre-test probability of LVNC group. Two independent blinded radiologists established the diagnosis of LVNC based on NC/C ratio > 2.3 on CMRI, and they were allowed to re-assess the patients following the diagnostic flowchart. RESULTS: An NC/C ratio > 2.3 identified 83 of 84 LVNC patients, yet incorrectly classified 48 of the 162 controls as having LVNC. Radiologists changed their decision in 23 of 48 patients with incorrect diagnoses, resulted in improved specificity (70.4% to 84.6%). The use of the CMRI diagnostic flowchart in the high pre-test probability group yielded a high specificity (97.2%) and accuracy (95.9%). CONCLUSIONS: LVNC diagnosed by CMRI based on the NC/C criterion can lead to overdiagnosis, whereas only using CMRI in patients with a high pre-test probability of LVNC with all available sequences may improve the diagnostic performance.
ABSTRACT
AIM: Several scoring systems, such as controlling nutritional status (CONUT) score, geriatric nutritional risk index (GNRI), and prognostic nutritional index (PNI), have been previously described to show nutritional status. In the present study, we aimed to investigate the value of these scoring systems in predicting in-hospital and long-term mortality in patients undergoing surgical aortic valve replacement (SAVR). METHODS: PNI, GNRI, and CONUT were determined using the receiver operator characteristics curve analysis in 150 consecutive elderly patients (age: 70 (66-74) years, male: 78) who underwent SAVR due to degenerative severe aortic stenosis (AS). Patients were divided into two groups according to cutoff values from these indexes. RESULTS: During the 50 ± 31 months follow-up period, a total of 36 (24%) patients died. 30-day mortality, 1-year mortality, and total mortality were significantly higher in lower PNI, lower GNRI, and higher CONUT groups. PNI cutoff value was 49.2, GNRI cutoff value was 102.5, and CONUT cutoff value was 1.5. PNI ≤ 49.2, GNRI ≤ 102.5, and CONUT > 1.5 values were found to be independent predictors of total mortality even after risk adjustment. In addition, in the mortality group, PNI (53.7 ± 5.9 vs. 47.4 ± 6.3; p < .001) and GNRI (108 ± 10 vs. 99 ± 6.3); p < .001) were significantly lower, while CONUT score (1 [0-2] vs. 2 [0.2-3]; p < .001) was significantly higher. CONCLUSION: Objective nutritional indexes including CONUT score, PNI, and GNRI are important prognostic factors and those indexes should be part of frailty assessment in patients with severe AS.

Saphenous vein graft (SVG) percutaneous coronary interventions (PCIs) are procedures with potential complications such as distal embolization, slow or no-reflow phenomenon. Platelets are the main factors in development of thrombus and no-reflow phenomenon. There have been multiple studies that identified the association between plateletcrit (PCT) and cardiovascular outcomes. The aim of the study was to investigate whether PCT can predict the development of no-reflow in patients with non-ST elevation myocardial infarction (NSTEMI) undergoing PCI for SVG disease. A total of 181 patients who underwent PCI for SVG disease with NSTEMI were included retrospectively. Platelet indices on admission were recorded. Patients were divided into two groups according to the development of no-reflow during the procedure: no-reflow (nâ=â32; 18%) and normal reflow (nâ=â149; 82%). PCT and platelet count were higher in the no-reflow group (0.254 vs. 0.224, Pâ=â0.020; 265.4 vs. 233, Pâ=â0.011, respectively). The PCT cut-off value for predicting no-reflow was calculated as 0.230 by ROC curve analysis with 68.8% sensitivity and 51.0% specificity. Multivariate logistic regression analysis showed that PCT was an independent predictor of no-reflow (odds ratio: 5.091, confidence interval: 1.356-19.116, Pâ=â0.016). PCT may be useful in identifying patients at risk for developing no-reflow in patient with NSTEMI undergoing SVG PCI.

OBJECTIVE: This prospective study aimed to investigate the myocardial energy metabolism in severe mitral regurgitation (MR) and explore its effect on postoperative differentiation of ejection fraction (EF). METHODS: A total of 85 patients with severe MR were prospectively enrolled from October 2018 to June 2019. During the study period, a total of 50 patients underwent mitral valve surgery and 49 patients were finally enrolled due to 1 missing data. Left ventricular function, circumferential end-systolic stress (cESS), and myocardial energy expenditure (MEE) were measured by transthoracic echocardiography preoperatively and 3 months after surgery. Patients were divided into 2 groups according to absolute difference of postoperative differentiation of EF. RESULTS: Nine patients underwent mitral valve repair and 40 underwent prosthetic valve replacement. Patients with reduced EF had higher MEE demonstrated with cESS and MEE. Negative correlation between preoperative EF and N-terminal pro-brain natriuretic peptide (NT-proBNP), cESS, MEEs, and MEEm and positive correlation between preoperative EF and effective regurgitant orifice area were found. Complications occurred in 12 patients during hospitalization. Basal NT-proBNP, left atrium (LA), and cESS were significantly higher in postoperatively decreased EF group. Taking into consideration the covariates of multiple logistic regression analysis, LA and cESS were found to be independent predictors of EF reduction postoperatively. CONCLUSION: Higher LA and cESS are independent predictors of postoperative EF reduction. Preoperative high end-systolic stress could predict postoperative EF reduction and hence could be helpful for determining the timing of mitral valve surgery. Although MEE was higher in postoperatively decreased EF group, it did not reach statistical significance.

OBJECTIVE: Transcatheter aortic valve implantation (TAVI) is a good alternative to surgical aortic valve replacement (SAVR) in severe aortic stenosis patients who are at intermediate or high risk, or other cases that are considered unsuitable for SAVR. TAVI is most often performed on elderly patients, and although conventional risk scores include a number of comorbidities, they do not take into account functional decline specific to elderly patients. The prognostic nutritional index (PNI), which is a simple and effective parameter for both nutritional and inflammatory status, reflects functional decline in the elderly. The aim of this study was to determine the effect of the PNI on short-term survival after TAVI. METHODS: The PNI values of 302 patients who underwent TAVI were analyzed. The study population was divided into 2 groups according to a PNI cut-off value: PNI >43.37 (n=213; 70%) and PNI <43.37 (n=89; 30%). RESULTS: Patients with a lower PNI score had a significantly higher mortality rate in the initial 30-day period following the procedure than patients with a higher PNI score (3.3% vs. 31.5%; p<0.001). Major vascular complications and cardiac tamponade were significantly more frequent in the lower PNI group. The cut-off value of the PNI for 30-day survival was 43.37, with 94.3% specificity and 73.4% sensitivity and the negative predictive value of the PNI was 96.7%. The PNI score was found to be an independent risk factor for 30-day mortality after TAVI. CONCLUSION: A higher PNI score was associated with short-term survival and fewer post-TAVI complications.

BACKGROUND: Percutaneous coronary intervention (PCI) of saphenous vein grafts (SVGs) is associated with an increased risk of complications, particularly noreflow phenomenon and distal embolization due to low patency rates. The CHA2DS2VASc score is a clinical risk stratification tool used to predict thromboembolism events especially in patients with nonvalvular atrial fibrillation. AIM: The aim of this study was to investigate the relationship between the CHA2DS2VASc score and noreflow phenomenon after SVG PCI in patients with non-STsegment elevation acute coronary syndromes (NSTEACS). METHODS: In this study, we included 268 patients diagnosed with NSTEACS who underwent PCI for SVG disease in our tertiary cardiovascular center. Patients were divided into 2 groups: group 1 without noreflow phenomenon (n = 190) and group 2 with noreflow phenomenon (n = 78) following the intervention, and then compared based on CHA2DS2VASc scores. RESULTS: The CHA2DS2VASc score (P <0.001) was significantly higher in group 2, even though no significant difference regarding atrial fibrillation was observed between the study groups. The CHA2DS2VASc score (P <0.001), degenerated saphenous vein graft (P = 0.006), and intraluminal thrombus (P <0.001) were found to be independent predictors of noreflow phenomenon. Receiver operating characteristics analysis showed that a CHA2DS2VASc score of 4 predicted noreflow phenomenon with 67.9% sensitivity and 69.3% specificity. CONCLUSIONS: Our findings suggest that the CHA2DS2VASc score can be an independent predictor of noreflow phenomenon in patients undergoing SVG interventions. As a simple and easytocalculate score, it might be a useful assessment tool to predict noreflow phenomenon before SVG interventions in patients with NSTEACS.

BACKGROUND: Post-operative changes in electrocardiography (ECG) after lung surgery have been investigated in prior researches. We have limited data about benign physiologic changes in ECG after lung surgery, specifically after lung resection. The aim of our study was to investigate relationship in between lung resection with minimally invasive robotic or video-assisted thoracoscopic surgery (VATS) and its effect on ECG after lung resection. METHODS: After exclusion criteria had been applied, a total of 133 patients were enrolled in the present study. Operational information such as amount of resected segment and side of resection was recorded. Lung resections were divided into two groups. One group included surgeries with lung resections <3 segments and other group included surgeries with segmentectomy ≥3 segments. Pre-operative and postoperative (in between 2nd and 3rd months) ECG data of the patients were compared. The location of resected segments as left-sided and right-sided resections were noted to compare the ECG changes for sub-analysis. RESULTS: Among 133 patients, 101 patients were male (75.9%). There was no significant difference between parameters including ventricular rate, P wave, QRS wave and T wave axis in degrees, PR, QRS, QT and QTc durations, Tpe interval, ratio of Tpe interval to QT and QTc interval and fQRSTa. There was significant difference between before and after resection in terms of degree of QRS axis (before resection =37.3 ± 52.7 vs. after resection = 26.2 ± 55.7, P = .026). Sub-analysis regarding to amount of resected segments, there was no significant difference identified in terms of QRS axis in degrees between before and after resection for patients who underwent lung resection <3 segments (p = .885). However, there was significant difference in QRS axis in degrees for patients who underwent lung resection ≥3 segments (before resection = 47.3 ± 57.5 vs. after resection = 23.7 ± 66.2, P = .010). There was significant rightward axial change after left-sided lung resections (before resection =32.0 ± 52.4 vs. after resection = 49.4 ± 47.1, P = .005) and leftward axial change after right-sided lung resection (before resection = 41.7 ± 53.0 vs. after resection = 7.1 ± 55.2, P < .001). CONCLUSION: Understanding and recognition of possible ECG changes are crucial during post-operative follow-up of the patients who underwent lung resection. These changes might be benign changes, which are related to anatomical and geometrical changes within thoracic cavity.

OBJECTIVE: The influence of the Ramadan fasting on blood pressure (BP) in patients taking diuretics therapy has not been addressed specifically yet. The aim of this study was to examine the effect of long Ramadan fasting on BP with ambulatory BP monitoring in hypertensive patients using diuretics. METHODS: This prospective, observational study was done on 129 hypertensive patients and was carried out in two groups: 73 treated hypertensive patients were assigned to the diuretic group and 56 treated hypertensive patients were allocated to the non-diuretic group. Twenty-four-hour ambulatory BP monitoring was performed during and after Ramadan. Mean overall, daytime and nighttime BP were measured and compared in both groups. The differences in mean SBP and DBP were recorded between the two monitoring periods. RESULTS: In diuretic group, 24-h SBP decreased from 128.2 ± 17.9 to 119.3 ± 9.5 mmHg during Ramadan (8.9 units; P < 0.001). DBP decreased from 79.4 ± 10.9 to 75.3 ± 7.6 mmHg (4.1 units; P < 0.001). On the other hand, SBP and DBP were lower insignificantly in the non-diuretic group. The reduction in SBP was significantly higher in the diuretic group (overall: P = 0.005, daytime: P = 0.011, nighttime: P = 0.022). Thiazide-like diuretics lowered BP more than thiazide-type diuretic despite an insignificant difference. CONCLUSION: This study suggested that Ramadan fasting might cause significant reductions in mean SBP and DBP measurements in patients using diuretics. Despite decreasing in BP, diuretics generally well tolerated and can be safe in well-controlled hypertensive patients during Ramadan fasting.

OBJECTIVES: Type A aortic dissection (TAD), which consists of an intimal tear in the aorta, necessitates emergency surgery. Various risk factors related to aortic dissection have been defined in the literature. According to our hypothesis, a narrower angle of ascending aortic curvature (AAAC) may be an additional risk factor in relation to aortic dissection due to the increased force applied to the aortic wall. METHODS: Patients undergoing ascending aortic surgery due to an ascending aortic aneurysm (AsAA) (n = 105) and patients undergoing such surgery because of the occurrence of TAD (n = 101) were enrolled in this study. The AAAC was measured using Cobb's method; the measurements were made on all patients by just 1 cardiovascular radiologist using 3-dimensional computerized tomographic imaging. This measurement was made indirectly by using the aortic valve and brachiocephalic artery to avoid obtaining misleading data as a result of distortions due to dissection. A statistical comparison was also performed relating the traditional risk factors for TAD to other clinical and echocardiographic parameters: the diameter of the ascending aorta and the AAAC. RESULTS: The AAAC was found to be narrower statistically in the TAD group (α = 76.2° ± 17.5°) than it was in the AsAA group (α = 92.9° ± 13°) (P < 0.001). Furthermore, mean ascending aortic diameter (P = 0.019), the presence of a bicuspid aorta (P = 0.007) and aortic valve stenosis (P = 0.005) were higher in the AsAA group. According to multivariable analyses, a narrower AAAC is a significant predictor for the development of TAD (odds ratio 0.93, 95% confidence interval 0.91-0.95; P < 0.001). Overall hospital mortality from various causes including stroke, myocardial infarction, bleeding or renal failure was 13% in the TAD group and 7% in the AsAA group. CONCLUSIONS: According to this study, the AAAC was significantly smaller in aortic dissection patients than in aortic aneurysm patients. This may be related to higher shear stress and elevated pressure on the ascending aorta in patients with a narrower AAAC. Thus, a narrower AAAC may be an additional risk factor in the development of TAD. Therefore, we may need to be more careful in terms of looking for the development of aortic dissection in patients with narrower AAAC.
