Abstract
Background Diffuse long coronary lesions are difficult to treat percutaneously. The aim of the present study was to assess the procedural safety and long-term efficacy of the ultra-long (48-mm) drug-eluting stent Xience Xpedition. Methods This was an investigator-initiated, observational, all-comers study. A total of 92 patients with 93 lesions were enrolled in the study from October 2016 to October 2020. The primary outcome of the study was major adverse cardiac events (MACEs). Secondary outcomes were individual components of the primary outcome and procedural success. Results The mean (standard deviation (SD)) age of the participants was 58.8 (10.8) years. More than half of the patients had ST-segment elevation myocardial infarction (STEMI) at presentation (55.4%). Ten patients were in cardiogenic shock (CGS; 10.8%). Most of the lesions were located in the left anterior descending artery (48.3%). American College of Cardiology/American Heart Association (ACC/AHA) type C was the most common lesion type amongst the intervened vessels (46.74%), with a mean syntax score (SD) of 16.99 (8.89). The mean stent diameter used was 2.77 mm (0.25). MACE was observed in 7.6% of patients studied at a median follow-up of 24 months. MACE was significantly lower in the population without CGS, occurring in only 2.4% of the patients; a significant difference in MACE was observed in patients with and without CGS (P < 0.001). Procedural success was obtained in 89.2% of total population; however, 96.3% of patients without CGS had procedural success. Conclusions The deployment of the ultra-long 48-mm Xience Xpedition stent is feasible, safe, and effective; and it was associated with a good intermediate-term clinical outcome.

Abstract
Objectives:
Insulin resistance (IR), which plays a fundamental role in the pathogenesis of metabolic syndrome and type 2 diabetes mellitus, is associated with serum levels of inflammatory markers and abdominal obesity. Whether the association of inflammation with IR is independent of obesity remains unresolved; moreover, whether this association varies with gender and urban living is not known. We therefore conducted a cross-sectional study to investigate the gender specific association between IR and high sensitive C-reactive protein (HsCRP), independent of abdominal obesity, in urban and rural communities in a South Asian population.
Methods:
We conducted a population-based cross-sectional survey in 8,080 South Indians above the age of 20 years in both urban and rural environments. The study assessed of waist circumference (WC), blood pressure (BP), socioeconomic status, family history, anxiety and stress levels, and fasting blood for plasma glucose, insulin, total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), low density lipoprotein (LDL) and HsCRP. IR was calculated using the homeostasis model assessment (HOMA-IR). After the exclusion of individuals with diabetics, 6,309 subjects (mean age 42 years; 58% women) were eligible and constituted the study sample.
Results:
The HOMA-IR level (mean ± SD) was higher in women (1.98 ± 1.62), when compared to men (1.71 ± 1.38), and HsCRP levels were 4.00 ± 5.14 and 3.42 ± 7.22 mg/dl in women and men, respectively. There was stronger correlation of HsCRP with HOMA-IR in women (r= 0.371) when compared to men (r= 0.203). In a multiple regression analysis, after adjusting for WC and other co-variants such as, BP, TC, LDL, TG, socioeconomic status, physical activity and family history of diabetes, HsCRP continued to be a significant predictor only in women (p<0.001). In women with elevated HsCRP levels (≥ 3 mg/dl), after multivariate adjustments, the odds ratio of elevated HOMA-IR (≥ 2.86) was 2.13 [CI: 1.66, 2.74; p <0.001] in urban women, when compared to odds ratio of 1.41 [CI: 1.02, 1.96; p=0.037] in rural women.
Conclusion:
HsCRP is associated with IR independent of abdominal obesity in non-diabetic South Asian women, and at elevated HsCRP levels the association is stronger in urban women.

Tetralogy of Fallot in adults--107 cases. THE JOURNAL OF THE ASSOCIATION OF PHYSICIANS OF INDIA 1995; 43:25-7. [PMID: 9282634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 02/05/2023]
Abstract
Clinical and haemodynamic profile of 107 adult patients above the age of 15 years with TOF was analysed. Cardiac catherization and selective cine-angiography were performed in all cases. Infundibular pulmonary stenosis, mal-alignment type of ventricular septal defect, mitral-aortic fibrous continuity and equal systolic pressures in both the ventricles and aorta were considered mandatory for the diagnosis of Tetralogy of Fallot. Aortic regurgitation was seen in 26 cases (24%), tricuspid regurgitation in 22 cases (21%), absent pulmonary valve in 3 cases (3%), branch pulmonary artery stenosis in 9 case (8.4%), major aortopulmonary collaterals in 15 cases (14%), right atrial pressure was more than 10 mmHg in 10 cases (11%) and right ventricular end diastolic pressure more than 9 mmHg in 73 cases (68%). The left ventricular end diastolic pressure was above 13 mmHg in 58 cases (54%).

Abstract
The records of 362 patients of Ventricular Septal Defect (VSD) were analysed to find out the incidence of aortic regurgitation (AR) and their hemodynamic and angiographic features. Thirty-seven patients (10.2%) were found to have AR, whose mean age was 13.4 years (range: 2-45) and male to female ratio was 5:1. Of the 37 cases 31 (84%) had infracristal and 6 (16%) had supracristal VSD. In 31 patients with infracristal VSD the prolapsing cusp was Right Coronary Cusp (RCC) in 14 (48%), Noncoronary Cusp (NCC) in 12 (41%) and both RCC and NCC in 3 (11%). Of the 6 patients with supracristal VSD the prolapsing cusp was RCC in 5 (83%) and NCC in 1 (17%). In two patients the AR was due to bicuspid aortic valve. The pulmonary artery pressure was normal in 26 of 37 (70.2%) patients and the left to right shunt was 1.5:1 or less in 23 of 37 (62%) patients. Nineteen of the 37 patients (51.3%) had grade I or II AR and the remaining 18 (48.7%) had grade III or IV AR. There was no relationship between the severity of AR and the location of the VSD. In conclusion, in this series, the incidence of VSD+AR is relatively higher and that of supracristal VSD is lower. In majority of patients the left to right shunt is small and pulmonary artery pressure within normal limits. The prolapse of RCC is more common in supracristal VSD and there is no relation between the severity of AR and the location of the VSD.

Abstract
The hemodynamic data and electrocardiograms of thirty-three patients of moderate to severe aortic stenosis were analysed retrospectively to find out if there was any correlation between 12 lead ECG-QRS score and left ventricular peak systolic pressure (LVPSP) and/or peak systolic gradient (PSG) across the aortic valve. The mean age of the study population was 33.33 (+/- 15.02SD) years, with the male to female ratio being 9:2. The mean 12 lead ECG-QRS score in these 33 patients was 281 mm (+/- 46.02SD), the mean LVPSP 203.52 mmHg (+/- 46.62SD) and the mean PSG across the aortic valve was 81.0 mmHg (+/- 41.62SD). There was good correlation of 12 lead ECG-QRS score with LVPSP (r = 0.47, P less than 0.001) and with PSG across the aortic valve (r = 0.58, P less than 0.001), latter being more significant. The best correlation was however found between 12 lead ECG-QRS score and PSG across the aortic valve in patients over 35 years of age (r = 0.88). In conclusion there is a direct relationship between 12 lead ECG-QRS score and peak systolic gradient across the aortic valve and the latter can be approximately calculated non-invasively with the help of regression equation- Peak systolic gradient (in mmHg) = 12 lead ECG-QRS score/3 - 10.6

Myocardial bridge (MB): an angiographic curiosity? Indian Heart J 1989; 41:296-300. [PMID: 2599538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/01/2023] Open
Abstract
The coronary angiograms of 1,500 cases performed between 1981 and 1989 were analysed to find out the incidence of Myocardial Bridge (MB) and its significance as regards myocardial ischemia. Sixteen of these (1.06%) were found to have MB. Their ages ranged from 27-70 years (m = 49.2) and male:female ratio was 13:3. Out of 16 patients, 7 (group A) had associated coronary artery disease (CAD) (7 of 1421; 0.49%) and remaining 9 (group B) had no associated CAD (9 of 79; 11.39%). All the MB were found on left anterior descending artery (LAD) (3 on proximal LAD and 13 on mid LAD). No MB was found on right coronary artery (RCA) or circumflex arteries. The location of the MB did not affect the pattern of CAD. Chronic stable angina was the commonest presenting symptom in group A patients (5 out of 7) and atypical angina in group B patients (5 out of 9). Majority of group B patients had either normal or nonspecific ST-T changes in ECG (7 out of 9). However, the presence of previous myocardial infarction or ECG evidence of 'Q' wave infarction (2 out of 2) was always associated with significant CAD. Similarly, regional wall motion abnormalities on echocardiogram were always found in patients with significant CAD and old myocardial infarction. All 9 patients with MB and normal coronary arteries were managed conservatively with good relief of symptoms, whereas other seven patients were managed on the merits of the underlying CAD. In conclusion, the MB is a normal variant found incidentally on coronary angiography, and does not have any definite clinical correlations or pathological significance.

Abstract
The relationship between the mean frontal QRS axis calculated from the scalar 12 lead ECG, and the pulmonary artery (PA) pressures obtained by cardiac catheterisation in 64 cases of isolated rheumatic mitral stenosis (MS), was analysed. An overall trend of rightward axis shift with increasing PA pressures was observed; the best correlation was seen with systolic PA pressures (r = 0.51). It was possible to recognise 3 categories of patients: (1) With an axis of 70 degrees and below, systolic PA pressures were below 70 mm Hg in 82.4% of cases and below 80 mm Hg in 94% of cases; diastolic pressures were below 40 mm Hg in 88.2%; mean PA pressures were below 50 mm Hg in 88.2% cases. (2) With an axis of 71 degrees to 100 degrees, systolic PA pressures ranged from 30 to 120 mm Hg, diastolic PA pressures from 12 to 60 mm Hg and mean PA pressures from 19 to 80 mm Hg. (3) With an axis of above 100 degrees, systolic PA pressures were over 70 mm Hg in 95.5% of cases, diastolic PA pressures more than 30 mm Hg in 90.9%, and mean PA pressures more than 45 mm Hg in 90.9% cases. It was therefore possible to predict, with reasonable accuracy, the range of PA pressures in patients with isolated MS, except in those cases with an axis between 71 and 100 degrees.

Abstract
Thirty-five patients of chronic stable angina, unstable angina and post MI angina, who were on medical treatment, underwent 24 hours Holter monitoring and coronary angiography to find out the incidence of Silent Myocardial Ischemia (SMI) and its relation to anatomic severity of coronary artery disease. Total duration of Holter monitoring was 835.32 hours (average 23.40 hours per patient) with 48 ischemic episodes out of which 16 were painful and 32 painless. Total duration of painful episodes was 189 minutes and that of painless episodes was 428 minutes (70% was constituted by SMI). Out of 35 patients, 6 (17.14%) had SMI; 2 of 17 (11.7%) of chronic stable angina, 2 of 8 (25%) of unstable angina, and 2 of 10 (20%) of post-infarction angina patients. On analysis of coronary angiogram, all 6 (100%) patients with SMI, and only 22 out of 29 (76%) without SMI, had severe multiple coronary artery disease. Thus, although the overall incidence of SMI in this series is low, its presence invariably indicates a severe degree of coronary artery disease.

Abstract
Over the last 1-year period, we performed 130 consecutive percutaneous transluminal coronary angioplasty (PTCA) procedures in 108 patients, 103 of them were males and 5 females. Their mean age was 50.9 +/- 6.83 years (range 33-70). All of them were symptomatic, manifested by acute infarction in 18 (17%), chronic stable angina in 30 (28%), unstable angina in 5 (5%) and post-myocardial infarction angina in 55 (51%) cases. Among these patients, single-vessel CAD was present in 42 (39%), double-vessel in 37 (34%) and triple-vessel CAD in 11 (10%) patients. Nine patients (8.3%) had total occlusion, and 18 (16.6%) had tandem or bifurcation lesions of target artery. Of the 112 PTCA procedures (excluding those in acute infarction), 53 (47%) were performed on LAD, 29 (26%) on RCA, and 30 (27%) on circumflex artery, with success rates of 86.7%, 83.3% and 82.7% respectively. The overall success rate was 85% (95 of 112). The PTCA was successful in 36 of 42 (85.7%), 32 of 37 (86.5%) and 9 on 11 (82%) patients with single, double and triple-vessel CAD respectively. The mean diameter stenosis reduced from 67.1 +/- 16.54% to 19.9% +/- 10.9%. PTCA was unsuccessful in 17 (15%) due to failure to cross the lesion in 11 (9.7%), failure to dilate in 1 (0.9%) and abrupt reclosure of dilated segment in 5 (4.4%). Four (3.5%) patients underwent CABG. Two patients had redo PTCA owing to restenosis at about 6 months of first PTCA.(ABSTRACT TRUNCATED AT 250 WORDS)
