Heart failure (HF) is a major public health problem, with an increased readmission rate particularly in the first 30 days after HF admission. Reducing HF readmissions requires a multidisciplinary team, and home telemonitoring jointly with home nurse visits was shown to be beneficial. We performed a

OBJECTIVES:Takotsubo cardiomyopathy (TTC) is an acute cardiac syndrome simulating myocardial infarction that is characterized by transient wall motion abnormalities in the absence of coronary artery obstruction. Reverse TTC (rTTC) is a recently described variant of TTC. This review defines and compares both forms of TTC, stating their resemblances and differences.METHODS:We conducted a search of the MEDLINE database. Forty-one cases of rTTC met our eligibility criteria and were summarized in a synthesis of the demographic features, clinical characteristics, and laboratory studies.RESULTS:Of the 41 patients studied, 73% were women. Patients' ages ranged from 19 to 69 years and the mean age was 43. The predominant electrocardiogram finding was ST-segment depression, whereas ST-segment elevation was present in only 6 patients (14.5%). Troponin levels were raised in 92.6% of the patients, with a mean troponin I of 7.7 ng/mL. All of the patients had wall motion abnormalities on echocardiography and the mean ejection fraction was 29.3%. Of the 27 patients (66%) who had a documented angiography, 22 (81.5%) had normal coronaries and 5 (18.5%) had minor or mild obstructive coronary artery disease. Of the 41 patients, 9 (22%) died, and the mean recovery time of the ejection fraction in the survivors was 16 days.CONCLUSIONS:rTTC is a distinct presentation from the classic TTC. Remarkable differences exist between both forms in terms of mean age, sex, electrocardiogram presentation, troponin levels, and mortality.

In this paper, we prove an existence result for ℒ^∞ -solutions for a class of semilinear delay evolution inclusions with measures and subjected to nonlocal initial conditions of the form {[ du(t)= {Au(t)+f(t)}dt+dh(t), t∈ℝ_+,; f(t)∈ F(t,u_t), t∈ℝ_+,; u(t)=g(u)(t), t∈ [ -τ ,0 ]. ]. Here τ≥ 0 , X is a Banach space, A:D(A)⊆ X → X is the infinitesimal generator of a C_0 -semigroup, F:ℝ_+×ℛ([ -τ ,0 ];X)⇝ X is a u.s.c. multifunction with nonempty, convex and weakly compact values, h∈ BV_loc(ℝ_+;X) and the function g:ℛ_b(ℝ_+;X)→ℛ([ -τ ,0 ];X) is nonexpansive.

BACKGROUND:Acute coronary syndrome (ACS) during postpartum period is rare. In the current manuscript we present a case of a postpartum patient who developed ACS attributed to coronary vasospasm in the absence of vasocontrictive medication or smoking. This condition resolved with intracoronary injection of nitroglycerine and verapamil.CASE:A 26-year-old woman, postpartum day five, presented with a sudden onset of chest pain and an acute ST-segment elevation on ECG. Coronary artery catheterization showed multiple areas of spasm, which was relieved by intracoronary injection of nitroglycerine and verapamil. Post-catheterization hospital stay was uneventful and the patient was discharged in a stable condition.CONCLUSIONS:Early diagnosis and treatment of ACS in the peripartum period is crucial. Vasospastic coronary disease should be included in the differential diagnosis of peripartum chest pain. Nitrates are still considered the best treatment option with or without calcium channel blockers for both recurrence and prevention.

We consider a class of abstract evolution reaction-diffusion systems with delay and nonlocal initial data of the form $$ \begin{cases} \displaystyle u'(t)\in Au(t)+F(t,u_t,v_t)&\text{for } t\in \mathbb{R}_+,\\ v'(t)\in Bv(t)+G(t,u_t,v_t) & \text{for } t\in \mathbb{R}_+,\\ u(t)=p(u,v)(t)& \text{for } t\in [-\tau_1,0],\\ v(t)=q(u,v)(t)& \text{for } t\in [-\tau_2,0], \end{cases} $$ where $\tau_i\geq 0$, $i=1,2$, $A$ and $B$ are two $m$-dissipative operators acting in two Banach spaces, the perturbations $F$ and $G$ are continuous, while the history functions $p$ and $q$ are nonexpansive functions with affine growth. We prove an existence result of $C^0$-solutions for the above problem and we give an example to illustrate the effectiveness of our abstract theory.

Abstract We consider an abstract nonlinear multi-valued reaction-diffusion system with delay and, using some compactness arguments coupled with metric fixed point techniques, we prove some sufficient conditions for the existence of at least one C0-solution.

We establish a sufficient condition for the existence, uniqueness and global uniform asymptotic stability of a C-0-solution for the nonlinear delay differential evolution equation{ u'(t) is an element of Au(t) + f(t,ut), t is an element of R+, u(t) = g(u) (t), t is an element of [-tau, 0],where tau > 0, X is a real Banach space, A is the infinitesimal generator of a nonlinear semigroup of contractions, f : R+ x C([-tau,0]; <(D(A)))over bar> -> X is continous and g : C-b([-tau +infinity); <(D(A)))over bar> -> C([-tau,0]; <(D(A)))over bar> is nonexpansive.

We prove some sufficient conditions for the existence and global uniform asymptotic stability of C0-solutions for a class of nonlinear delay reaction–diffusion systems subjected to nonlocal initial conditions. Some applications to a specific reaction–diffusion system are included.

We prove the continuity of the $C^0$-solution with respect to the right-hand side and the initial nonlocal condition to the nonlinear delay differential evolution equation $$\left\{\begin{array}{ll} \displaystyle u'(t)\in Au(t)+f(t,u_t),&\quad t\in \mathbb{R}_+, \\[1mm ] u(t)=g(u)(t),&\quad t\in [\,-\tau,0\,], \end{array}\right.$$ where $\tau>0$, $X$ is a real Banach space, $A$ is an $m$-dissipative operator, $f:\mathbb{R}_+\times C([\,-\tau,0\,];\overline{D(A)})\to X$ is Lipschitz continuous with respect to its second argument and $g:C_b([\,-\tau,+\infty);\overline{D(A)})\to C([\,-\tau,0\,];\overline{D(A)})$, is nonexpansive.

The purpose of this paper is to prove some necessary and sufficient conditions in order that the graph K of the multi-function K : I -> <(D(A))over bar> x <(D(B))over bar> be C-0-viable with respect to the nonlinear system of the form{u'(t) is an element of Au(t) + F(t, u(t), v(t)), t >= tauv'(t) is an element of Bv(t) + G(t, u(t), v(t)), t >= tauu(tau) = xi, v(tau) = eta,where I subset of R is an open from the right interval, X and Y are real Bana.ch spaces, A : D (A) subset of X -> X and B : D(B) subset of Y -> Y are m-dissipative operators generating nonlinear semigroups of contractions, F : X -> X is a given function and G : K -> Y is a nonernpty valued multi-function. We provide a necessary and sufficient condition in order that the system has at least one C-0-solution (u, v) satisfying time-dependent constrains (u(t), v(t)) is an element of K(t) for each t. We include a comparison result referring to a nonlinear system with multi-valued perturbations of subdifferentials in a Hilbert space.

In this paper we consider a nonlinear evolution reaction–diffusion system governed by multi-valued perturbations of m -dissipative operators, generators of nonlinear semigroups of contractions. Let X and Y be real Banach spaces, 𝒦 be a nonempty and locally closed subset in ℝ× X× Y, A:D(A)⊆ X⇝ X, B:D(B)⊆ Y⇝ Y two m -dissipative operators, F:𝒦→ X a continuous function and G:𝒦⇝ Y a nonempty, convex and closed valued, strongly-weakly upper semi-continuous (u.s.c.) multi-function. We prove a necessary and a sufficient condition in order that for each (τ,ξ,η)∈𝒦 , the next system {[ u'(t)∈ Au(t)+F(t,u(t),v(t)) t≥τ; v'(t)∈ Bv(t)+G(t,u(t),v(t)) t≥τ; u(τ)=ξ, v(τ)=η, ]. has at least one C 0 -solution ( u , v ) : [ τ, T ] → X × Y with (t,u(t),v(t))∈𝒦 for each t∈ [ τ,T ].

We consider a reaction-diffusion system of the form{u'(t) = Au(t) + F(u(t), v(t)), t >= 0u'(t) = Bv(t) + G(u(t), v(t)), t >= 0u(0) = xi, v(0) = eta,where X and Y are real Banach spaces, K is a nonempty and locally closed subset in X x Y, A : D(A) subset of X -> X, B : D(B) subset of Y -> Y are the generators of two C-0-semigroups, {S-A(t) : X -> X; t >= 0} and {S-B(t) : Y -> Y; t >= 0} respectively, F : K -> X, G : K -> Y are continuous such that A + F and/or B + G are locally of beta-compact type. We prove some necessary and sufficient conditions in order that for each (xi, eta) is an element of K, problem above has at least one mild solution (u, v) : [0, T] -> K.
