RESUMO
BACKGROUND: The method of hemostasis for the distal radial approach has not been standardized, although this approach has become increasingly popular due to its advantages. In this study, we investigated the feasibility of manual compression hemostasis using a calcium alginate pad after coronary angiography via the distal radial approach. METHODS: We retrospectively collected 150 consecutive patients (mean age, 74.9 ± 8.0 years; male, 75 %) who underwent coronary angiography via the distal radial artery with a predominantly 4 Fr sheath from April 2021 to December 2022 and were hemostatic according to the following methods. After sheath removal, hemostasis was achieved by manual compression for 10 min using a hemostatic pad containing calcium alginate. When hemostasis was confirmed, a small log-shaped gauze was placed over the pad and fixed using a self-adhesive elastic bandage for 2 h. All procedures were performed by four fellows just beginning the distal radial approach. RESULTS: The mean compression time was 12.4 ± 4.8 min, and hemostasis was successfully achieved in all patients, allowing the release of the elastic bandage after 2 h, with only one patient oozing the next morning. There were no major complications, while one patient had a >10 cm hematoma. Compared to that of the first 15 patients, for each fellow, the compression time of the subsequent patients was significantly shorter (14.5 ± 6.7 vs 11.1 ± 2.1 min, p < 0.01). CONCLUSIONS: Manual compression hemostasis using calcium alginate pads for the distal radial artery approach appears feasible with a simple learning.
RESUMO
BACKGROUND: The Morning Hypertension and Angiotensin Receptor Blocker/Hydrochlorothiazide Combination Therapy (MAPPY) study has shown that losartan/hydrochlorothiazide (HCTZ) combination is superior to high-dose losartan in not only reducing morning systolic blood pressure (SBP) but also ameliorating urinary albumin excretion (UAE) after 3-month treatment. The purpose of the present study was to investigate factors associated with UAE reduction in on-treatment patients with morning hypertension. METHODS AND RESULTS: A total of 95 patients registered in the MAPPY study were analyzed. Patients were treated with either a losartan/HCTZ combination regimen (n=47) or a high-dose losartan regimen (n=48). Three-month treatment significantly reduced morning SBP, evening SBP, and clinic SBP (P<0.001, P<0.05, and P<0.01, respectively). UAE and serum uric acid were significantly decreased (P<0.01 for both) without the change in estimated glomerular filtration rate. Multiple linear regression analysis indicated that %morning SBP reduction and baseline UAE were independent determinants of the UAE reduction (P=0.001 for both). After adjustments for the reduction in morning-evening SBP difference, baseline UAE, and %uric acid reduction, estimated %UAE reduction level was positively correlated with the tertiles of the increasing %morning SBP reduction level (P=0.031 for trend). Moreover, subgroup analysis showed that morning SBP reduction was an independent determinant of UAE reduction in both treatment regimens. CONCLUSIONS: Reduction in morning SBP was a key factor in UAE reduction in patients with morning hypertension, irrespective of treatment regimen.

Previous studies have identified risk factors for short- and long-term outcomes for patients undergoing percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). However, it remains unknown whether they can be generalized to current PCI practice for a broader cohort of patients. We analyzed the follow-up information (mortality and revascularization procedures) obtained from a nationwide Japanese registry during 1997 of a total of 2,211 patients with AMI who underwent PCI at 143 facilities. Demographic, clinical, angiographic, and procedural variables were submitted to statistical analysis to detect the risk factors of adverse outcomes. In-hospital and 1-year mortality rates were 7.1% and 10.9%, respectively. The most important risk factor for in-hospital death was attempted PCI of the left main (LM) coronary artery. Further independent risk factors for death were left ventricular (LV) dysfunction (ejection fraction =40%), LM disease, older age, multivessel disease, cerebrovascular disease, and diabetes. The receiver-operating characteristics curve for the predicted probability of death was 0.88, indicating a good ability to discriminate high-risk patients. Independent risk factors for 1-year postdischarge mortality were LV dysfunction, older age, renal failure, multivessel disease, and diabetes. The incidence of the need for repeat PCI or bypass surgery was significantly higher in patients with multivessel and LM disease. PCI is a valuable treatment strategy for a broad spectrum of patients with AMI. However, the mortality for patients with LM disease and poor LV function is still high even using current practice standards.

BACKGROUND: The purpose of this study was to use a contemporary database to examine the relationship between annual hospital volume and the outcomes of percutaneous coronary interventions (PCIs) for acute myocardial infarction (AMI), given the wide spread use of coronary stents. An inverse relation exists between the number of PCIs and short-term outcome, but PCI practice has been changing with the availability of new devices such as stents. METHODS AND RESULTS: Data from the 1997 Japanese nationwide registry were analyzed to determine the relation between the annual hospital volume of PCI procedures for patients with AMI and in-hospital mortality, as well as the need for coronary artery bypass graft (CABG) surgery. A total of 129 hospitals (2,491 patients) were divided into terciles according to the annual volume. Of the procedures, 39% involved coronary stents. Median annual PCI volumes varied across terciles from low =10, middle =33, and high =89. After adjusting for patient characteristics, there was no significant relationship between volume and in-hospital mortality (trend P=0.66) and CABG (trend P=0.35). Among patients who received stents (n=958), there was no significant association between volume and either mortality or CABG. CONCLUSIONS: Using the contemporary database, there was no significant relationship between hospital volume and in-hospital outcome among AMI patients undergoing PCIs.

Randomized clinical trials have demonstrated that coronary stenting is more successful than balloon angioplasty in improving short- and long-term outcomes. However, it remains unknown whether those results can be generalized to broad-based practice. This study aimed to determine whether the outcome for patients with acute myocardial infarction (AMI) undergoing coronary stent placement would be better than those undergoing balloon angioplasty. The risk-adjusted mortality and subsequent revascularization rates were compared for 2185 patients from a nationwide Japanese registry during 1997. A total of 1349 patients were treated with balloon angioplasty alone and 836 had stent placement. There were no statistically significant differences in the prevalence of demographic, clinical, and angiographic variables, except that the angioplasty group had a greater proportion of female patients and those with a left circumflex lesion. Unadjusted in-hospital mortality was comparable (7.6 vs 6.3%; p=0.28), despite higher angiographic success rate for the stent group (89.7 vs 97.7%; p<0.01). Adjusted odds ratio for in-hospital mortality was 0.75 (p=0.19). The same-admission bypass surgery rate was also similar. The 1.9-year post-discharge mortality rate was similar. The need for subsequent revascularization procedures was also similar, but restenosis was significantly lower in the stent group (34 vs 45%; p<0.01). The superiority of clinical outcome for stenting rather than balloon angioplasty could not be demonstrated in broad-based registry patients, despite technically successful results.

A survey by the Japanese Coronary Intervention Study (JCIS) group revealed that 109,788 percutaneous coronary intervention (PCI) procedures were performed at 1,023 laboratories during 1997. The present study aimed to describe the demographic and clinical characteristics, treatment strategies, in-hospital outcomes, and long-term outcomes of these patients. A total of 10,642 PCIs performed in 8,814 patients, which corresponded to approximately 10% of the overall PCIs, were selected at random. The mean patient age was 65 years, and 75% were males. The patients often had extensive coronary risk factors. The most prevalent clinical diagnosis was stable angina (36%), followed by myocardial infarction (MI) excluding acute myocardial infarction (AMI; 28%) and AMI (25%). Plain old balloon angioplasty was used as the sole procedure in 58% of lesions for which an attempt to heal was made, and coronary stent placement in 38%. Angiographic success was achieved in 92% of attempted lesions. Mortality, MI and emergency coronary artery bypass grafting (CABG) rates during the hospitalization were 2.6%, 2.0% and 0.7%, respectively. In-hospital mortality rate for AMI was 7.6%, whereas that for elective PCI in cases without AMI was 0.6%. The overall mortality for 1.8 years was 8%. Repeat PCI was performed for 35% and CABG for 6% during the follow-up period. In Japan, PCI was performed in patients with coronary artery disease and extensive risk factors, but a high rate of angiographic success was achieved. The rates of in-hospital mortality and emergency CABG were low in non-AMI patients, but the 1-year rate of repeat PCI was as high as 32%.

The Japanese Coronary Intervention Study (JCIS) has revealed that 17,667 coronary artery bypass grafting (CABG) procedures were performed at 477 facilities during 1997, and this report describes the demographic and clinical characteristics, treatment strategies, and the in-hospital and the long-term outcomes in patients treated with CABG in Japan. A total of 1,862 CABG cases, which corresponded to approximately 10% of the overall CABGs, were selected at random. The mean age was 65 years, and 76% of cases were males. The most prevalent clinical diagnosis was stable angina (54%), followed by myocardial infarction (MI) excluding acute myocardial infarction (AMI) (48%), unstable angina (25%), and AMI (5%). A large proportion of cases had multivessel coronary artery disease: 3-vessel disease (56%) and left main trunk disease (29%). The CABG procedures were emergency in 16%, and 93% of anastomotic sites were patent. In-hospital mortality and MI occurred in 5.1% and 3.5% of cases, respectively. The in-hospital mortality rate for emergency CABG was 12.0%, whereas that for elective CABG was 3.8%. The overall mortality rate during the follow-up period of 2.3 years was 10%. During the follow-up period, MI and angina occurred in 2% and 8% of cases, respectively. Percutaneous coronary intervention (PCI) was performed for 8%, and repeat CABG for 0.8%. In Japan, CABG was performed in patients with multivessel coronary artery disease with extensive risk factors. Angiographically determined success was achieved in 93% and the need for subsequent revascularization was relatively low.
