Background: Contrast-induced nephropathy (CIN) is the third leading cause of hospital-acquired acute renal failure.Objective: The purpose of the present study was to compare the incidence and associated risk factors of contrast induced nephropathy in diabetes and non-diabetic patients.Methodology: This was cross-sectional study performed in the Department of Nephrology at National Institute of Kidney Diseases and Urology, Sher-E-Bangla Nagar, Dhaka and Department of Cardiology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from January 2016 to July 2016. Contrast induced nephropathy (CIN) is defined as increase in serum creatinine of ≥25% from baseline value and/ or an absolute increase of ≥0.5 mg/dl in serum creatinine from baseline. Patients were divided in to two groups Group A (Patients with Diabetes mellitus) and Group B (Patients without Diabetes mellitus). To identify independent characteristics associated with CIN, multivariable logistic regression analysis was used through SPSS version 23. Results of this model were presented as Odds Ratio (OR). P value was calculated to see the significance of various risk factors in diabetes and non-diabetes patients.Results: The difference in baseline creatinine serum creatinine was found statistically significant (P<0.001). In group A 57 patients (50.9%) had eGFR <60ml/min/1.73m2, 55 patients (49.1%) had eGFR ≥60ml/min. The difference in estimated GFR was found statistically significant (P<0.001). Left ventricular ejection fraction <40% was present in 6 (5.4%), 7 (5.1%) in group A and B respectively, ≥40% in 106 (94.6%), 131 (94.9%) in group A and B respectively. CIN developed in 21 (18.80%) patients in group A and 2 (1.4%) patients in group B (CIN was defined by increased in serum creatinine ≥25% of baseline or ≥44μmol/L). All belonged to group A, 16 (19%) of the diabetic patients out of 86 developed CIN. Diabetic patients who had eGFR <60ml/min (n=30), 13 (43.3%) developed CIN. Among all patients (n=250), 23 developed CIN. Overall incidence was 9.2%.Conclusion: CIN was significant developed in diabetes group than non diabetes. Left ventricular ejection fraction and total volume of contrast media used was significantly higher in diabetes group than non-diabetes group B patients.Journal of National Institute of Neurosciences Bangladesh, 2017;3(1): 29-36

This paper investigates the effect of rehabilitation training on the clinical outcome and prognosis of patients with acute myocardial infarction after coronary artery intervention. There was no significant difference in daily living ability score and left ventricular ejection fraction between group A before intervention (P>0.05). The score of daily living ability of group A was (76.58±3.27) significantly higher than that of group B after intervention (73.7). ±3.4) (P<0.05); left ventricular ejection fraction after intervention (55.75±4.4) was significantly higher than that of group B (52.41 ±4.19) (P<0.05); total satisfaction rate of patients in group A (93.02%) was significantly higher In group B (69.77%), the difference between the groups was statistically significant (P<0.05); the total incidence of adverse reactions and mortality in group A (11.63%, 2.33%) was significantly lower than that in group B (53.49%, 16.28%).), the difference was statistically significant (P < 0.05). In patients with acute myocardial infarction, after interventional coronary artery intervention, immediate intervention with rehabilitation training can improve left ventricular ejection fraction, improve daily living ability and nursing satisfaction, and reduce postoperative adverse reactions and death. Medical staff should be used reasonably in the clinic according to the actual situation of the patient.

Sudden strenuous exercise (SSE) has been shown to produce ischemic electrocardiographic (ECG) responses, abnormalities of myocardial blood flow, and decreases in left ventricular ejection fraction. Prior exercise taken as warm-up has been shown to ameliorate the ECG and myocardial blood flow abnormalities induced by SSE. The purpose of this study was to determine whether warm-up would normalize the responses of the left ventricular ejection fraction to SSE. Twenty healthy male volunteers performed SSE (400-W bicycle exercise) either with (group A, n = 10) or without (group B, n = 10) warm-up. Ejection fraction was measured using first-pass radionuclide angiography under control conditions and during SSE. During SSE ejection fraction decreased from control values in both group A (70.5 +/- 6.3 to 64.8 +/- 8.2%) and group B (70.3 +/- 10.1 to 57.7 +/- 7.7%), although ejection fraction was significantly higher during SSE in group A. The results are consistent with the hypothesis that the abnormal responses to SSE are attributable to subendocardial ischemia secondary to a delay in autoregulation of myocardial blood flow. However, the decrease in ejection fraction during SSE even following warm-up suggests that the mechanism for the abnormal response to SSE is more complicated than previously hypothesized.

Abstract Background The optimal choice of conduit and configuration for coronary artery bypass grafting (CABG) in diabetic patients remains somewhat controversial, even though arterial grafts have been proposed as superior. We attempted to clarify the role of complete arterial revascularization using the left internal thoracic artery (LITA) and the radial artery (RA) alone in “T-Graft” configuration on long-term outcome. Methods and Results From 1994 to 2001, 104 diabetic patients with triple vessel disease underwent CABG using LITA/RA “T-Grafts” (Group-A). Using propensity-score matching, 104 patients with comparable preoperative characteristics who underwent CABG using LITA and one sequential vein graft were identified (Group-V). Freedom from all causes of death, cardiac death, major adverse cardiac event (MACE), major adverse cardiac (and cerebral) event (MACCE), and repeat revascularization at 10 years of Group-A was 60 ± 5%, 67 ± 5%, 48 ± 5%, 37 ± 5%, and 81 ± 4%, respectively, compared with 58 ± 5%, 70 ± 5%, 49 ± 5%, 39 ± 5%, and 93 ± 3% in Group-V. There were no significant differences in these end points between groups regardless of insulin-dependency. Multivariable Cox proportional hazards model identified age, left ventricular ejection fraction, renal failure, and hyperlipidemia as independent predictors for all death, age and left ventricular ejection fraction for cardiac death, sinus rhythm for both MACE and MACCE, and prior percutaneous coronary intervention for re-revascularization. Conclusions In our experience, complete arterial revascularization using LITA/RA “T-Grafts” does not provide superior long-term clinical benefits for diabetic patients compared with a combination of LITA and sequential vein graft.

Background. Patients following major cardiac surgery are increasingly elderly and present many comorbidities. For these reasons their post-operative phase is often burdened by several complications requiring a long stay in Critical Care and prolonged mechanical ventilation. Most of these patients, when transferred to our Intensive Cardiac Rehabilitation Unit, still have a percutaneous tracheostomy due to respiratory mechanical dysfunction. The aim of our work is to present new rehabilitative care strategies in such compromised patients. Methods and materials. We studied 27 elderly critically ill tracheostomized patients who were split into 2 Groups (A = 11 and B = 16). The Groups were homogeneous for age and for left ventricular ejection fraction. Group A received a standard treatment including cautious mobilisation and respiratory unspecific physiotherapy. Group B received an earlier and more aggressive treatment with a specific respiratory physiotherapy including Positive Expiration Pressure (PEP) directly connected to the tracheostomy cannula. A protocol for tracheostomy decannulation by assessment of the Peak Expiratory Flow during cough (PCEF≥ 180 L/min.) has been defined in order to verify the patients ability to develop a mechanically effective cough to obtain weaning from tracheostomy. Besides, in the patients of Group B, we carried out a screening of the swallowing dysfunction. Results. Four patients of Group A deceased while in Group B there were no deaths. Furthermore patients of Group B showed a statistically significant improvement of mobility and respiratory indexes. In Group B only one patient was discharged with tracheostomy cannula in site because he did not reach standard criteria for decannulation and his PCEF value was not satisfactory. This patient underwent percutaneous gastrostomy. Conclusions. A precocious and intensive rehabilitation, based on specific respiratory physiotherapy, significantly improves mobility and respiratory indexes of patients with tracheostomy. The PCEF and the swallowing deficit evaluation allows an earlier tracheostomy decannulation with lower risk of complications.

Abstract Aims Complications of acute myocardial infarction (MI) can be life-threatening leading to sudden cardiac death. While guidelines recommend prompt revascularization and prolonged intensive care hospitalization, predictors of major adverse cardiovascular outcomes are yet poorly understood. The role of implantable cardioverter-defibrillators, even in cases of non-sustained arrhythmias is still debated. To date, it is unknown how to follow-up patients with mild cardiac dysfunction after MI. Implantable cardiac monitors (ICMs) can be helpful for stratifying patients in the early discharge period, and remote monitoring might speed up arrhythmia recognition and treatment. We investigated the role of remote monitoring of ICMs to detect arrhythmic events in post-MI patients without overt cardiac dysfunction. Methods and results We enrolled 13 patients (9 males; 69.8 years) after either ST-segment (N = 7) or non-ST-segment elevation (N = 6) MI with a left ventricular ejection fraction (LVEF) &gt;35%, admitted to our coronary care unit for urgent revascularization between September 2019 and September 2021. Twelve patients underwent percutaneous myocardial revascularization, whereas one was treated with medical therapy only. All patients received an ICM during hospitalization according to echo and EKG parameters. We considered LVEF ≤ 40% as sole risk factor or LVEF between 40% and 50% in addition to either PQ length prolongation, or QRS widening, or pathologic heart rate variability, or non-sustained ventricular tachycardia/paroxysmal advanced second degree atrioventricular block. Patients with multiple revascularization procedures and several hospital admissions were excluded. Implanted ICM were frequently monitored both remotely and in-office when required. During follow-up, brady- and tachy-arrhythmias were recorded in four patients (30.8%). The remote monitoring of the ICM documented new-onset atrial fibrillation, high-degree atrioventricular block, severe bradycardia, and sustained ventricular tachycardia. Three patients required hospitalization and upgrade of the implanted device with pacemakers and cardioverter/defibrillator. For arrhythmic risk stratification, patients were divided into two subgroups; group A included patients with LVEF 40% associated with heart rate &gt; 60 b.p.m., PQ length &gt;160 ms and QRS width &gt;86 ms (N = 4); group B included patients with EF 41%/50%, PQ length &lt;159 and QRS width &lt;85 ms (N = 10). First group experienced more advanced rhythm disorders than group B (P &lt; 0.05). Device implantation was significantly higher in group A (P &lt; 0.05%). Conclusions OFF-label implementation of ICMs coupled with remote device monitoring may be effective for early detection of serious adverse cardiac rhythm alterations in patients after MI and LVEF higher than 35%. Further monitoring is ongoing for assessing the occurrence of multiple arrhythmias or their increased occurrence.

Abstract Background Truncating variants in FLNC gene are associated with an overlapping phenotype of arrhythmogenic and dilated cardiomyopathy. There are reports of high arrhythmia propensity with sudden cardiac death (SCD) often being the first symptom of the disease. It has been suggested that the current European guidelines primary prevention (PP) recommendation about implantable cardioverter-defibrillator (ICD) implantation might not be applicable in these patients and that earlier intervention should be considered. Purpose We sought to investigate the arrhythmic burden in FLNC truncation carriers in our centre. Methods Adult FLNC truncation carriers diagnosed in our centre between the years 2018 and 2019 were included in the study. We retrospectively analysed clinical data, and ICD follow-up reports in the cohort. Patients implanted with an ICD were divided in 3 groups: group A (secondary prevention ICD implantation), group B (PP indication according to the current guidelines – left ventricular ejection fraction (LVEF) below 35%) and group C (early PP– FLNC truncation carrier, LVEF &lt; 50% and late gadolinium enhancement on cardiac magnetic resonance). We report the number of patients experiencing SCD and the number of appropriate and inappropriate ICD therapies per group. Results Twenty-four adult patients from 3 different families with three distinct FLNC truncating variants were identified. Ten (42%) were male; the average age was 45 ± 14 years. There were 3 (13%) SCDs in one family (2 male and one female, 29-42 years old) and two (8%) aborted SCDs in the remaining two families (one male and one female, 66 and 51 years old). Altogether eleven (46%) patients were implanted with an ICD. There were three patients in group A (2 aborted SCDs and 1 sustained ventricular tachycardia (VT)), two patients in group B and six patients in group C. Average ICD follow-up times were 42, 48 and 6 months for groups A, B and C, respectively. Eight appropriate ICD therapies occurred in 3 patients (27%). In group A, there were four sustained VT episodes successfully converted with an anti-tachycardia pacing (ATP) in two patients (67%); the average time to first therapy was 33 months. In group B, there was one appropriate shock for ventricular fibrillation (VF), and three sustained VT episodes in one patient (50%), time to first therapy was 60 months. After six months follow-up, there were no appropriate therapies registered in group C. Two patients (18%) experienced inappropriate shocks due to sinus tachycardia, one in group A and one in group C. Conclusion One-fifth of FLNC truncation carriers in our cohort experienced SCD. When patients received an ICD according to the current guidelines, majority experienced appropriate ICD therapy. Further clinical studies with longer follow-up will be needed to define appropriate risk stratification and optimal timing for prophylactic ICD intervention in these patients.

Objective Contrast-induced nephropathy (CIN) is a serious complication in patients with acute coronary syndrome (ACS) and percutaneous coronary intervention (PCI). This study aimed to analyze the potential risk factors for CIN in patients undergoing PCI. Methods Patients with ACS who underwent PCI treatment from January 2017 to January 2020 were selected. The patients’ characteristics and medical information were collected and compared. Results A total of 1331 patients undergoing PCI were included. The incidence of CIN was 15.33%. Logistic regression analyses showed that a left ventricular ejection fraction ≤45% (odds ratio [OR] 4.18, 95% confidence interval [CI] 1.10–7.36), serum creatinine levels ≤60 μmol/L (OR 3.03, 95% CI 1.21–5.57), age ≥65 years (OR 2.75, 95% CI 1.32–4.60), log N-terminal pro-B-type natriuretic peptide levels ≥2.5 pg/mL (OR 2.31, 95% CI 1.18–5.13), uric acid levels ≥350 μmol/L (OR 2.29, 95% CI 1.04–5.30), emergency percutaneous intervention (OR 1.35, 95% CI 0.34–3.12), and triglyceride levels ≤1.30 mmol/L (OR 1.10, 95% CI 0.01–2.27) were independent risk factors for CIN in patients who underwent PCI. Conclusions Early prevention is required to reduce the occurrence of CIN in patients who undergo PCI and have risk factors for CIN.

Insulin-induced hypoglycemia occurs commonly in intensively treated patients with type 1 diabetes, but the cardiovascular consequences of hypoglycemia in these patients are not known. We studied left ventricular systolic [left ventricular ejection fraction (LVEF)] and diastolic [peak filling rate (PFR)] function by equilibrium radionuclide angiography during insulin infusion (12 pmol · kg−1 · min−1) under either hypoglycemic (∼2.8 mmol/l) or euglycemic (∼5 mmol/l) conditions in intensively treated patients with type 1 diabetes and healthy nondiabetic subjects ( n = 9 for each). During hypoglycemic hyperinsulinemia, there were significant increases in LVEF (ΔLVEF = 11 ± 2%) and PFR [ΔPFR = 0.88 ± 0.18 end diastolic volume (EDV)/s] in diabetic subjects as well as in the nondiabetic group (ΔLVEF = 13 ± 2%; ΔPFR = 0.79 ± 0.17 EDV/s). The increases in LVEF and PFR were comparable overall but occurred earlier in the nondiabetic group. A blunted increase in plasma catecholamine, cortisol, and glucagon concentrations occurred in response to hypoglycemia in the diabetic subjects. During euglycemic hyperinsulinemia, LVEF also increased in both the diabetic (ΔLVEF = 7 ± 1%) and nondiabetic (ΔLVEF = 4 ± 2%) groups, but PFR increased only in the diabetic group. In the comparison of the responses to hypoglycemic and euglycemic hyperinsulinemia, only the nondiabetic group had greater augmentation of LVEF, PFR, and cardiac output in the hypoglycemic study ( P < 0.05 for each). Thus intensively treated type 1 diabetic patients demonstrate delayed augmentation of ventricular function during moderate insulin-induced hypoglycemia. Although diabetic subjects have a more pronounced cardiac response to hyperinsulinemia per se than nondiabetic subjects, their response to hypoglycemia is blunted.

Anthracycline-based regimens with or without anti-human epidermal growth factor receptor (HER) 2 agents such as trastuzumab are effective in breast cancer treatment. Nevertheless, heart failure (HF) has become a significant side effect of these regimens. This study aimed to investigate the incidence and factors associated with HF in breast cancer patients treated with anthracyclines with or without trastuzumab. A retrospective cohort study was performed in patients with breast cancer who were treated with anthracyclines with or without trastuzumab between 1 January 2014 and 31 December 2018. The primary outcome was the incidence of HF. The secondary outcome was the risk factors associated with HF by using the univariable and multivariable cox-proportional hazard model. A total of 475 breast cancer patients were enrolled with a median follow-up time of 2.88 years (interquartile range (IQR), 1.59–3.93). The incidence of HF was 3.2%, corresponding to an incidence rate of 11.1 per 1000 person-years. The increased risk of HF was seen in patients receiving a combination of anthracycline and trastuzumab therapy, patients treated with radiotherapy or palliative-intent chemotherapy, and baseline left ventricular ejection fraction <65%, respectively. There were no statistically significant differences in other risk factors for HF, such as age, cardiovascular comorbidities, and cumulative doxorubicin dose. In conclusion, the incidence of HF was consistently high in patients receiving combination anthracyclines trastuzumab regimens. A reduced baseline left ventricular ejection fraction, radiotherapy, and palliative-intent chemotherapy were associated with an increased risk of HF. Intensive cardiac monitoring in breast cancer patients with an increased risk of HF should be advised to prevent undesired cardiac outcomes.

ObjectivePatients with SLE have increased risk of myocardial infarction (MI). Few studies have investigated the characteristics of SLE-related MIs. We compared characteristics of and risk factors for MI between SLE patients with MI (MI-SLE), MI patients without SLE (MI-non-SLE) and SLE patients without MI (non-MI-SLE) to understand underlying mechanisms.MethodsWe identified patients with a first-time MI in the Karolinska SLE cohort. These patients were individually matched for age and gender with MI-non-SLE and non-MI-SLE controls in a ratio of 1:1:1. Retrospective medical file review was performed. Paired statistics were used as appropriate.ResultsThirty-four MI-SLE patients (88% females) with a median age of 61 years were included. These patients had increased number of coronary arteries involved (p=0.04), and ≥50% coronary atherosclerosis/occlusion was numerically more common compared with MI-non-SLE controls (88% vs 66%; p=0.07). The left anterior descending artery was most commonly involved (73% vs 59%; p=0.11) and decreased (<50%) left ventricular ejection fraction occurred with similar frequency in MI-SLE and MI-non-SLE patients (45% vs 36%; p=0.79). Cardiovascular disease (44%, 5.9%, 12%; p<0.001) and coronary artery disease (32%, 2.9%, 0%; p<0.001), excluding MI, preceded MI/inclusion more commonly in MI-SLE than in MI-non-SLE and non-MI-SLE patients, respectively. MI-SLE patients had lower plasma albumin levels than non-MI-SLE patients (35 (29–37) vs 40 (37–42) g/L; p=0.002).ConclusionIn the great majority of cases, MIs in SLE are associated with coronary atherosclerosis. Furthermore, MIs in SLE are commonly preceded by symptomatic vascular disease, calling for attentive surveillance of cardiovascular disease and its risk factors and early atheroprotective treatment.
