Profile of acute coronary syndrome in young diabetics: a review

The clinical presentation and angiographic findings of coronary artery disease (CAD) varies from diabetic and non-diabetic patients and varies with the age of presentation. Coronary artery disease in patients below the age of 45 is a special subset. The objective of this study is to compare the clinical and angiographic profile in patients with the acute coronary syndrome (ACS) with diabetes mellitus (DM) and without DM below the age of 45 years. Clinical Presentation of coronary artery disease in young patients with various risk factors differs, which plays an important role in management strategies. This was conducted through internet search on PubMed and ProQuest database from 2000 to until 2019. Key words used for searching are acute coronary syndrome, young diabetics, and clinical, angiographic profile. An important exclusion criterion is studies which included type one diabetic patients. Totally 35 papers were reviewed. Pattern of involvement of coronary arteries as assessed by the coronary angiographic study is found to be different in younger CAD patients. Atypical clinical presentation and distinct angiographic finding are common in diabetics below the age of 45. In most of the studies single vessel disease (SVD) is the most common angiographic finding in young CAD and non-diabetics. While the diabetics showed the more diffuse pattern of double vessel disease (DVD).

Rate of hemoglobin decline: indication optimization of transcatheter angiographic embolization after PCNL

Background To evaluate the clinical characteristics and angiographic features of transcatheter angiographic embolization (TAE) in patients with active bleeding after percutaneous nephrolithotomy (PCNL).Methods Between October 2009 and April 2018, 45 patients who underwent TAE for hemorrhage control after PCNL were reviewed retrospectively. Patient clinical characteristics and angiographic features of TAE were analyzed.Results Of the 3148 patients, 45 (1.4%), including 35 men (77.78%) and 10 women (22.22%), were treated with TAE after PCNL. Ten patients (22.22%) had a history of kidney surgery. The interval from the bleeding episode to TAE was 3 days (range, 1–6 days). In addition, 27 (60.0%) and 18 patients (40.0%) experienced sudden onset of bleeding and delayed bleeding, respectively. Arterial laceration, arteriovenous fistula, and negative angiographic finding was found in 28 (62.2%), 7 (15.6%), and 10 patients (22.2%), respectively. Thirty-five patients (92.1%) achieved primary clinical success. The median corrected hemoglobin decrease from bleeding episode to TAE was 52 g/L (25.25, 71.00). The median corrected hemoglobin decrease rate from bleeding episode to TAE was 13.11 g/L d (5.60, 26.12). The hemoglobin decrease from bleeding episode to TAE was lesser in negative angiographic patients (28.50 (10.75,51.25) g/L VS 53.7 (35.0,73.13) g/L) than in positive angiographic patients (P<0.05).Conclusion TAE is a safe and effective treatment for patients with post-PCNL bleeding. TAE should be performed for post-PCNL bleeding in patients with hemoglobin decrease of >25 g/L or hemoglobin decrease rate of >5.5 g/L·d following conservative management.

Tortuosity of the Internal Carotid Artery and Its Clinical Significance in the Development of Aneurysms

Tortuosity of blood vessels is a common angiographic finding that may indicate systemic disease and can be correlated with vascular pathologies. In this work, we determined whether patients with and without internal carotid artery (ICA) aneurysm presented with differences in its tortuosity descriptors. We retrospectively analysed data of 298 patients hospitalized between January 2014 and June 2018. For each patient’s imaging data, we extracted a curve representing the ICA course and measured its Relative Length (RL), Sum of Angle Metrics (SOAM), Product of Angle Distance (PAD), Triangular Index (TI), and Inflection Count Metrics (ICM). We found that patients with an ICA aneurysm had significantly lower RL (0.46 ± 0.19 vs. 0.51 ± 0.17; p = 0.023) and significantly higher SOAM (0.39 ± 0.21 vs. 0.32 ± 0.21 p = 0.003), PAD (0.38 ± 0.19 vs. 0.32 ± 0.21; p = 0.011), TI (0.30 ± 0.11 vs. 0.27 ± 0.14; p = 0.034), and ICM (0.30 ± 0.16 vs. 0.22 ± 0.12; p < 0.001). We found that that patients who presented with a subarachnoid hemorrhage had significantly higher PAD (0.46 ± 0.22 vs. 0.35 ± 0.20; p = 0.024). In conclusion, higher tortuosity of ICA is associated with ICA aneurysm presence.
