Contrast Induced Nephropathy: Efficacy of matched hydration and forced diuresis for prevention in patients with impaired renal function undergoing coronary procedures-CINEMA trial.

BACKGROUND: Matched hydration and forced diuresis (MHFD) using the RenalGuard device has been shown to reduce contrast induced nephropathy (CIN) following coronary interventions. AIM: To evaluate the potential benefits of a non-automated MHFD protocol compared to current hydration protocol in prevention of CIN in patients with CKD. METHODS: A total of 1,205 patients were randomized to either non-automated MHFD group (n = 799) or intravenous hydration control group (n = 406). The MHFD group received 250 ml IV normal saline over 30 min before the coronary procedure followed by 0.5 mg/kg IV furosemide. Hydration infusion rate was manually adjusted to replace the patient's urine output. When urine output rate reached > 300 ml/h, patients underwent coronary procedure. Matched fluid replacement was maintained during the procedure and for 4-hour post-treatment. CIN was defined conventionally as ≥ 25% or ≥ 0.5 mg/dl rise in serum creatinine over baseline. RESULTS: CIN occurred in 121 of 1,205 (10.0%) patients in our study. With respect to the primary outcome, 64 (8.01%) of the MHFD patients developed CIN compared with 57 (14.04%) of the control group (p < 0.001). CONCLUSIONS: A non-automated MHFD protocol is an effective and safe method for the prevention of CIN in patients with CKD.

Large vessel thrombosis in patient with COVID-19, a case series.

INTRODUCTION: Involvement of the large vessels is rarely reported and poorly understood in cases of Corona virus disease-19 (COVID-19). The aim of this study is to present a series of cases with large vessel thrombosis (LVT). METHODS: This is a multicenter prospective case series study. The participants were consecutive in order. All the patients were diagnosed as cases of COVID-19 with documented LVT were included in the study. Large vessels were defined as any vessel equal or larger than popliteal artery. The mean duration of follow up was 4 months. RESULTS: The study included 22 cases, 19 (86.4%) cases were male, 3 (13.6%) patients were females. The age ranged from 23 to 76 with a mean of 48.4 years. Four (18.2%) cases had pulmonary embolism confirmed by IV contrast enhanced chest CT scan. All of the cases showed pulmonary parenchymal ground glass opacities (GGO) and high D-Dimers (ranging from 1267 to 6038 ng/ml with a mean of 3601 ng/ml). CONCLUSION: COVID-19 is a hidden risk factor of LVT that may endanger the patient's life and lead to major amputation. Despite therapeutic anticoagulants still all COVID-19 patients are at risk for LVT, a high index of suspicion should be created and with minimal symptoms surgical consultation should be obtained.

Risk factors for acute coronary syndrome in patients below the age of 40 years.

BACKGROUND: Acute coronary syndrome (ACS) refers to a spectrum of symptoms compatible with acute myocardial ischemia. Plasma markers of inflammation have been recently identified as diagnostic aid and risk predictors. The present study, conducted in Slemani Cardiac Hospital (SCH), Sulaimaniyah, Iraq aimed to recognize some risk factors for ACS in Iraqi adults younger than 40. METHODOLOGY: This is a prospective case-control study of 100 patients with ACS vs. a control group of 100 healthy volunteers. The study began at 1st January 2014 and ended at 31st December 2016. All patients were subjected to full history taking, clinical examination including measurement of waist circumference and body mass index (BMI). Investigations included electrocardiography (ECG), echocardiography, full blood count, measurement of lipid profile and C-reactive protein (CRP). The patients were managed by percutaneous coronary intervention (PCI). RESULTS: The mean age of the patients was 36 years (range 28-40). Eighty-five% of patients were male. The mean BMI (29 kg/m2) and waist circumference (98 cm) of the patients were higher than the controls (24 kg/m2 and 72 cm respectively). The leukocytes, lymphocytes and neutrophil counts as well as CRP in both groups were within the normal range. The most prevalent risk factor was obesity (n = 86). Other risk factors were smoking (n = 62), hypertension (n = 26), diabetes mellitus (n = 22) and positive family history of ACS (n = 24). Most patients (n = 83) had multi-vessel coronary artery disease (2-3 vessels). CONCLUSION: ACS in young adults is an increasing health problem. Obesity was found to be the most prevalent risk factor.

Coronary artery perforation complicating percutaneous coronary intervention.

Background Coronary artery perforation is a rare but serious complication of percutaneous coronary interventions. We aimed to evaluate the management of coronary artery perforation in Sulaimaniyah, Iraq. Methods A retrospective review of our medical records from 2009 to 2016 identified 24 patients (15 males, 9 females) with coronary artery perforation. Mean age was 60 ± 9.2 years (range 40-74 years). Standard diagnostic angiography or percutaneous interventions were performed. Coronary artery perforation was diagnosed by worsening of symptoms, hypotension, or angiographic evidence of type I (extraluminal crater), II (myocardial or pericardial blushing), or III (contrast streaming or cavity spilling) perforation. Stenosis was graded as >85%, 60%-85%, or < 60%. Once coronary artery perforation was diagnosed, heparin was reversed, antiplatelets were stopped, and pericardial effusions were aspirated. Type II and III coronary artery perforations were sealed using covered stents or repeated brief balloon inflations. Results The most frequently injured artery was the left anterior descending ( n = 14, 58.3%). Type II and III coronary artery perforations constituted the majority ( n = 18, 75%). Thirteen (54.2%) patients had severe coronary stenosis. Perforations were caused by stents ( n = 10), angioplasty wires ( n = 8), and balloons ( n = 6). Fifteen perforations were sealed with covered stents, 2 by balloon inflations, and 7 resolved spontaneously. Pericardial effusion was drained in 13 (54.2%) patients. No patient required surgery, and none died. Conclusion The low rate and early management of coronary artery perforations, mainly by covered stents, were the hallmarks of this study.
