    Abstract Hypertension remains the leading modifiable risk factor for cardiovascular disease worldwide. Over the past 30 years, the prevalence of hypertension has been increasing in East and Southeast Asia to a greater extent as compared with other Western countries. Asians with hypertension have unique characteristics. This can be attributed to increased impact of obesity on Asians with hypertension, excessive salt intake and increased salt sensitivity, loss of diurnal rhythm in blood pressure and primary aldosteronism. The impact of hypertension on cardiovascular (particularly strokes) and chronic kidney disease is greater in Asians. These unique characteristics underpinned by the diverse socioeconomic backgrounds pose its own challenges in the diagnosis and management of hypertension in Asia.

    Abstract Objective: We aimed to evaluate the applicability of the eligibility criteria of randomized controlled trials (RCTs) cited in guideline recommendations in a real-world cohort of patients receiving secondary prevention after acute myocardial infarction from the EPICOR registries.
    Methods: Recommendations provided by American and European guidelines for acute myocardial infarction were classified into general (applying to all patients) and specific (applying to patients with left ventricular dysfunction or heart failure). Randomized controlled trials cited in these recommendations were selected, and their entry criteria were applied to our international cohort of 18,117 patients.
    Results: There were 91.5% patients eligible for beta blockers (84.6% for general, and 5.9% for specific recommendations), 97.7% eligible for renin-angiotensin system inhibitor (angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers [ACEI/ARB]) recommendations (69.9% for general, 27.9% for specific) and 4.1% eligible for mineralocorticoid receptor antagonists (only specific recommendations). The percentages of patients with eligibility criteria who were discharged with a prescription of the recommended therapies were 80%-85% for beta blockers, 70%-75% for ACEI/ARB, and 29% for mineralocorticoid receptor antagonists. There were large regional variations in the percentage of eligible patients and in those receiving the medications (eg, 95% in Northern Europe and 57% in Southeast Asia for beta blockers).
    Conclusion: Most real-world acute myocardial infarction patients are eligible for secondary prevention therapy in both general and specific guideline recommendations, and the percentage of those on beta blockers and ACEI/ARB at hospital discharge is high. There are large regional variations in the proportion of patients receiving recommended therapies. Local targeted interventions are needed for quality improvement.

    Abstract Background: Controversial findings have been reported in the literature regarding the impact of the absence of standard modifiable cardiovascular risk factors (SMuRFs) on long-term mortality risk in patients with acute coronary syndrome (ACS). While the prognostic additive value of SMuRFs has been well described, the prognostic role of prior cardiovascular disease (CVD) by sex is less well-known in patients with and without SMuRFs.
    Methods: EPICOR and EPICOR Asia are prospective, observational registries conducted between 2010 and 2014, which enrolled ACS patients in 28 countries across Europe, Latin America, and Asia. Association between SMuRFs (diabetes, dyslipidaemia, hypertension, and smoking) and 2-year postdischarge mortality was evaluated using adjusted Cox models stratified by geographical region.
    Results: Among 23,489 patients, the mean age was 60.9 ± 11.9 years, 24.3% were women, 4,582 (20.1%) presented without SMuRFs, and 16,055 (69.5%) without prior CVD. Patients with SMuRFs had a higher crude 2-year postdischarge mortality (HR 1.86; 95% CI, 1.56-2.22; P < .001), compared to those without SMuRFs. After adjustment for potential confounding, the association between SMuRFs and 2-year mortality risk was substantially attenuated (HR 1.17, 95% CI 0.98-1.41; P = .087), regardless of the type of ACS. The risk conferred by prior CVD was added to the underlying risk of SMuRFs to provide risk-specific phenotypes (eg, women with SMuRFs and with prior CVD were at higher risk of dying than women without SMuRFs and without CVD; HR 1.67, 95% CI 1.34-2.06).
    Conclusions: In this large-scale international ACS cohort the absence of SMuRFs was not associated with a lower adjusted 2-year postdischarge mortality risk. Patients with both SMuRFs and prior CVD had a higher mortality irrespective of their sex.

    Abstract Takayasu arteritis is a chronic inflammatory large vessel vasculitis affecting the aorta and its main branches. It can present in various forms, and thereby may lead to a delay in diagnosis. We present a patient with Takayasu arteritis, diagnosed at our center when she presented with severe aortic regurgitation. We also review the current knowledge base with respect to Takayasu arteritis.

    Abstract Patients with chronic kidney disease (CKD) have traditionally been excluded from randomized trials. We aimed to compare percutaneous coronary intervention versus conservative management, and early intervention (EI; within 24 hours of admission) versus delayed intervention (DI; after 24 to 72 hours of admission) in patients with non-ST-segment elevation myocardial infarction (NSTEMI) and concomitant CKD. An electronic literature search was performed to search for studies comparing invasive management to conservative management or EI versus DI in patients with NSTEMI with CKD. The primary outcome was all-cause mortality; secondary outcomes were acute kidney injury (AKI) or dialysis, major bleeding, and recurrent MI. Hazard ratios (HRs) for the primary outcome and odds ratios for secondary outcomes were pooled in random-effects meta-analyses. Eleven studies (140,544 patients) were analyzed. Invasive management was associated with lower mortality than conservative management (HR 0.62, 95% confidence interval 0.57 to 0.67, p <0.001, I

    Abstract Background: Compared with patients with hypertension only, those with hypertension and diabetes (HTN/DM) have worse prognosis. We aimed to characterize morphological differences between hypertension and HTN/DM using cardiovascular magnetic resonance; and compare differentially expressed proteins associated with myocardial fibrosis using high throughput multiplex assays.
    Methods: Asymptomatic patients underwent cardiovascular magnetic resonance: 438 patients with hypertension (60±8 years; 59% males) and 167 age- and sex-matched patients with HTN/DM (60±10 years; 64% males). Replacement myocardial fibrosis was defined as nonischemic late gadolinium enhancement on cardiovascular magnetic resonance. Extracellular volume fraction was used as a marker of diffuse myocardial fibrosis. A total of 184 serum proteins (Olink Target Cardiovascular Disease II and III panels) were measured to identify unique signatures associated with myocardial fibrosis in all patients.
    Results: Despite similar left ventricular mass (
    Conclusions: Adverse cardiac remodeling was observed in patients with HTN/DM. The novel proteomic signatures and associated biological activities of increased immune and inflammatory response may partly explain these observations.

    Abstract Background: The prognostic significance of focal and diffuse myocardial fibrosis in patients with cardiovascular risk factors is unclear.
    Methods: REMODEL (Response of the Myocardium to Hypertrophic Conditions in the Adult Population) is an observational cohort of asymptomatic patients with essential hypertension. All participants underwent cardiovascular magnetic resonance to assess for myocardial fibrosis: nonischemic late gadolinium enhancement (LGE), native myocardial T1, postcontrast myocardial T1, extracellular volume fraction including/excluding LGE regions, interstitial volume (extracellular volume×myocardial volume), and interstitial/myocyte ratio. Primary outcome was a composite of first occurrence acute coronary syndrome, heart failure hospitalization, strokes, and cardiovascular mortality. Patients were recruited from February 2016 and followed until June 2021.
    Results: Of the 786 patients with hypertension (58±11 years; 39% women; systolic blood pressure, 130±14 mm Hg), 145 (18%) had nonischemic LGE. Patients with nonischemic LGE were more likely to be men, have diabetes, be current smokers, and have higher blood pressure (
    Conclusions: In patients with hypertension, myocardial fibrosis on cardiovascular magnetic resonance is associated with adverse cardiac remodeling and outcomes.

    Abstract Background and objectives: We compared real-world clinical outcomes of patients receiving intravascular lithotripsy (IVL) versus rotational atherectomy (RA) for heavily calcified coronary lesions.
    Methods: Fifty-three patients who received IVL from January 2017 to July 2020 were retrospectively compared to 271 patients who received RA from January 2017 to December 2018. Primary endpoints were in-hospital and 30-day major adverse cardiovascular events (MACE).
    Results: IVL patients had a higher prevalence of acute coronary syndrome (56.6% vs 24.4, p<0.001), multivessel disease (96.2% vs 73.3%, p<0.001) and emergency procedures (17.0% vs 2.2%, p<0.001) compared to RA. In-hospital MACE (11.3% vs 5.9%, p=0.152), MI (7.5% vs 3.3%, p=0.152), and mortality (5.7% vs 3.0%, p=0.319) were not statistically significant. 30-day MACE was higher in the IVL cohort vs RA (17.0% vs 7.4%, p=0.035). Propensity score adjusted regression using IVL was also performed on in-hospital MACE (odds ratio [OR], 1.677; 95% confidence interval [CI], 0.588-4.779) and 30-day MACE (OR, 1.910; 95% CI, 0.774-4.718).
    Conclusions: These findings represent our initial IVL experience in a high-risk, real-world cohort. Although the event rate in the IVL arm was numerically higher compared to RA, the small numbers and retrospective nature of this study preclude definitive conclusions. These clinical outcomes are likely to improve with greater experience and better case selection, allowing IVL to effectively treat complex calcified coronary lesions.
